1938 Polish ultimatum to Lithuania

The 1938 Polish ultimatum to Lithuania was an ultimatum delivered to Lithuania by Poland on March 17, 1938. Five days earlier, Poland's southern borders were threatened by the annexation of Austria by Nazi Germany, therefore Poland decided it was imperative to deliver an ultimatum to Lithuania. As tensions in Europe intensified, Poland perceived the need to secure its northern borders. The Lithuanian government had steadfastly refused to have any diplomatic relations with Poland after 1920, protesting the annexation by Poland of the Vilnius Region.lt icon cite book | last=Skirius | first=Juozas | title=Gimtoji istorija.

The establishment of diplomatic relations would mean a "de facto" renunciation of Lithuanian claims to the region containing its historic capital, Vilnius (known in Polish as Wilno). Lithuania, preferring peace to war, accepted the ultimatum on March 19. Although diplomatic relations were established as a result of the ultimatum, Lithuania did not agree to recognize the loss of Vilnius "de jure". Poland made a similar move against the Czech government on September 30, 1938, when it took advantage of the Sudeten Crisis to demand a portion of Zaolzie. On both occasions, Poland used the international crises to address long-standing border disputes and to counter Germany's foreign policy iniatives.

Vilnius dispute

Lithuania severed its diplomatic ties with Poland after General Lucjan Żeligowski staged a mutiny in October 1920 by order of Józef Piłsudski.cite web| url=http://encarta.msn.com/sidebar_461500494/1938_lithuania.html |title=1938: Lithuania |publisher=MSN Encarta |work=Collier's Year Book |accessdate=2008-03-14] He invaded Lithuanian-held territory, captured the disputed city of Vilnius (known to Poles as Wilno), and established the short-lived Republic of Central Lithuania.

The League attempted to mediate the dispute and Paul Hymans presented concrete proposals to form a federation. However, both sides were unwilling to make compromises and negotiations collapsed in January 1922.

The result was a state of "no war, no peace" as Lithuania avoided recognizing any Polish claims to the city and the region, as well as refusing to undertake any actions that would recognize Poland's control of Vilnius even "de facto". Lithuania broke off all diplomatic relations with Poland and continuously emphasized that Vilnius remained its permanent capital (Kaunas was designated as the temporary capital). Poland refused to formally recognize the existence of any dispute regarding the region, since that would have lent legitimacy to the Lithuanian claims.

[cite journal | journal=New York Times |first=Emil |last=Lengyel |date=1939-03-20 |title=Poland and Lithuania in a Long Feud |pages=63] The conflict over Vilnius remained the most important foreign policy issue in Lithuania, but it became increasingly marginalized in the international arena. There were unsuccessful informal attempts to normalize the situation, most notably by the Lithuanian Prime Minister Augustinas Voldemaras between 1927 and 1928 and by Foreign Minister Stasys Lozoraitis between 1934 and 1936, who asked Smetona to re-establish the diplomatic relations with Poland. Both sides engaged in emotional and nationalistic rhetoric.cite book | last=Eidintas | first=Alfonsas | coauthors=Vytautas Žalys, Alfred Erich Senn | editor=Ed.

Rationale

On March 11, [Sometimes the day is incorrectly cited as March 7] a day before Austria was annexed into Greater Germany following the Anschluss, Justas Lukoševičius, a Lithuanian border patrol, shot Stanisław Serafin, a Polish soldier, on the demarcation line in the village of Trasninkai near Merkinė. The exact circumstances are not clear as the obscure event was variously portrayed as a Lithuanian provocation, a Polish provocation, or as an unfortunate accident.cite journal| title= The Polish–Lithuanian Crisis of 1938: Events Surrounding the Ultimatum |url=http://www.lituanus.org/1984_2/84_2_03.htm | first=Robert |last=Vitas |journal=Lituanus |volume=20 |issue=2 |date=Summer 1984 |id=ISSN 0024-5089 |accessdate=2008-03-02] During the 1920s and 1930s, similar incidents had occurred: between 1927 and 1937 seven Lithuanian border guards were killed during the course of 78 events.cite book | last=Eidintas | first=Alfonsas | coauthors=Vytautas Žalys, Alfred Erich Senn | editor=Ed. Edvardas Tuskenis | title=Lithuania in European Politics: The Years of the First Republic, 1918–1940 | edition=Paperback | year=1999 | month=September | publisher=St. Martin's Press | location=New York | isbn=0-312-22458-3 | pages=154–158] Usually, such incidents were handled at the local level in an attempt to forestall escalation. On this occasion, however, Polish radio and newspapers picked up the story and fanned anti-Lithuanian sentiment. Protests were held in Warsaw, Vilnius, and four other cities where the crowds shouted for military action against Lithuania. There is evidence that the Camp of National Unity was involved in organizing the protests.

On March 13, the Polish government issued a threatening statement accusing Lithuania of provocation. On the following day, the Senate of the Republic of Poland called for the establishment of diplomatic relations and for the Lithuanian renunciation of claims to Vilnius. Upon receiving news that Poland was considering extreme measures, President Antanas Smetona was verging towards agreeing to discuss diplomatic relations, but changed his mind at almost the last minute. On the night of March 14, the Lithuanians, acting through France's envoy to Warsaw, proposed a commission to investigate the shooting incident and to agree on measures to avoid such incidents in the future. This was a partial measure that clearly did not satisfy Poland, which responded by refusing, in the first paragraph of the ultimatum delivered three days later, to establish such a commission. At the same time Lithuanian diplomats approached foreign powers in a bid for international support.

Initial version

The first version of the ultimatum, as drafted by Edward Rydz-Śmigły, Prime Minister Felicjan Sławoj Składkowski, and Jan Szembek, contained six demands: [cite journal |journal=New York Times | title=Poland Sends An Ultimatum |first=Jerzy |last=Shapiro |date=1938-03-18 |pages=1]
# Establish normal diplomatic and consular relations with Poland
# Allow normal railway and road traffic and direct telephone and telegraph lines across the demarcation line
# Amend the Lithuanian constitution to acknowledge that Vilnius was no longer the capital of Lithuania
# Conclude the convention protecting the rights of the Polish minority in Lithuania in full
# Conclude a trade and tariff agreement
# Fully investigate the incident in Trasnykai

The Polish Foreign Minister Józef Beck, who had just returned from a trip to Sorrento, called for a government meeting on the night of March 16. During the meeting he argued that the ultimatum needed to contain only one demand: the establishment of diplomatic relations. In his view, such an ultimatum would not have violated any genuine Lithuanian interests and would offer much-improved prospects for peaceful resolution of the conflict and a speedy relief of tension. It was in accordance with Beck's vision for Eastern Europe, which was based on a Warsaw-dominated Polish–Baltic–Scandinavian bloc free of Soviet or German influence, [cite journal |journal=New York Times |title=Lithuania Surrenders | date=1938-03-21 |pages=14] a modified version of Józef Piłsudski's Międzymorze, which required the normalization of relations with Lithuania. The removal of the other demands also reflected political pressure on Poland from Russia, France, and England to prevent the conflict from escalating into warfare.cite journal| journal=New York Times | first=Clarence K. |last=Streit |title=Pressure on Poles Weakens Demands |date=1939-03-19 |pages=1]

The Polish government agreed to Beck's proposal, and the ultimatum was toned down. However, at the same time Beck ordered military preparations. Poland assembled four divisions along the demarcation line; about 50,000 Polish troops were present, and just over 20,000 Lithuanian troops.cite journal| title=Baltic Peace |journal=Time |url= http://www.time.com/time/magazine/article/0,9171,759356,00.html | date=1938-03-28 |accessdate=2008-03-14] The Polish troops were reinforced by armored vehicles, by two air force regiments, consisting of about one hundred aircraft, and by the Polish fleet in the waters of the Baltic Sea along the Lithuanian shore.

The ultimatum

The final text of the ultimatum, completed by Józef Beck and delivered through a Polish envoy in Tallinn to Bronius Dailidė, the Lithuanian ambassador in Estonia, was as follows:cite journal| title= Documents: The Polish Ultimatum to Lithuania – The Despatch of Lithuanian Minister J. Baltrušaitis in Moscow |url=http://www.lituanus.org/1985/85_4_02.htm | first=Robert |last=Vitas |journal=Lituanus |volume=31 |issue=4 |date=Winter 1985 |id=ISSN 0024-5089 |accessdate=2008-03-02]

:"1. The proposition of the Lithuanian Government of March 14 cannot be accepted for it does not give sufficient guarantees concerning the security of the frontier in view of the negative results of all Polish–Lithuanian negotiations made up to the present time".

:2. "For this reason the Polish Government declares that it considers as the only solution corresponding to the gravity of the situation the immediate establishment of normal diplomatic relations without any previous condition. This is the only way to regulate the neighborly questions for a Government animated by good faith to avoid events dangerous to peace."

:3. "The Polish Government allows the Lithuanian Government 48 hours from the moment the note is presented for the acceptance of this proposition in making it known that diplomatic representations at Kaunas and Warsaw will be accredited not later than March 31 of this year. Until that date all discussions of a technical or other character between the Polish and Lithuanian Governments shall be continued by the envoys extraordinary and ministers plenipotentiary at Tallinn.:The exchange of notes attached concerning the establishment of diplomatic relations shall take place, before the expiration of the period of 48 hours mentioned, at Tallinn between the Polish and Lithuanian Ministers at Tallinn."

:4. "The proposition above mentioned will not be the subject of discussion with regard to its content or form — it is an unchangeable proposition.The failure to respond or the presentation of any supplements or reservations shall be considered by the Polish Government as a refusal. In the event of a negative reply the Polish Government will guarantee the just interest of the state by its proper means."

The ultimatum contained an attachment: a draft of what would be deemed an acceptable response to the ultimatum. The proposed response stated only that Lithuania agreed to establish regular diplomatic relations, send a legation to Warsaw, and guarantee normal conditions of operation for a Polish legation in Kaunas.

International reaction

After the Soviet–Lithuanian Peace Treaty was ratified in 1920, the Russian SFSR recognized Lithuanian claims to the Vilnius Region and continued to support them. [cite book | last=Eidintas | first=Alfonsas | coauthors=Vytautas Žalys, Alfred Erich Senn | editor=Ed. Edvardas Tuskenis | title=Lithuania in European Politics: The Years of the First Republic, 1918–1940 | edition=Paperback | year=1999 | month=September | publisher=St. Martin's Press | location=New York | isbn=0-312-22458-3 | pages=109] In its responses to the 1938 ultimatum, the Soviet Union expressed concerns over Lithuania's independence and threatened to abrogate the Soviet-Polish Non-Aggression Pact of 1932. It made it clear, though, that it did not wish to be drawn into an armed conflict. This stance has been attributed to the growth of a threat from Japan; armed assistance to Lithuania would have required the Red Army to invade either Poland or Latvia and could have resulted in a war on two fronts. The Soviets urged France, a major ally of Poland at the time, to de-escalate the conflict and encourage a more moderate version of the ultimatum. France and England, preoccupied with the Anschluss, pressured Lithuania to normalize the relationship with Poland as soon as possible. They feared that the ultimatum had been approved by Nazi Germany. [cite journal| journal=New York Times |date=1938-03-16 |first=Clarence K. |last=Streit |title=Reich-Polish Deal Feared in Geneva |pages=11 ]

Germany, led by Adolf Hitler, now turned its attention to the Klaipėda Region, then held by Lithuania. In April 1938, Hitler stated that control of the Port of Klaipėda and its surrounding area was Germany's second-most important issue, following the status of the Sudeten area. [cite book | title=The Baltic and the Outbreak of the Second World War | first=John |last= Hiden | coauthors=Thomas Lane |page=53 |publisher=Cambridge University Press | year=1992| url= http://books.google.com/books?id=HzrpExvg2XgC&pg=PA53&sig=9o26IN7vq_kkMRx1-WzndpL29lg#PPA53,M1 | isbn= 0-521-53120-9 ] In the event of armed hostilites between Poland and Lithuania, German troops were to defend and occupy the Klaipėda region and significant portions of western Lithuania. The Polish ambassador to Nazi Germany, Józef Lipski, was informed of these plans. The Poles agreed to cooperate with German troops and to respect German interests in Klaipėda if such an armed conflict were to arise.cite book | first=Vilnis |last=Sipols |title=Diplomatic Battles Before World War II |url=http://leninist.biz/en/1982/DBBW313/3.1.4-Polish.Ultimatum.to.Lithuania |chapter=Polish Ultimatum to Lithuania |location=Moscow |publisher=Progress Publishers |year=1982 ] However, in Hitler's assessment, an immediate bid for Klaipėda was impolitic; he wished to maintain the "status quo" until more time had passed after the Anschluss. The German suggestion was that Lithuania concede to the Polish demands.

Lithuania, Latvia, and Estonia, the three Baltic states, had formed the Baltic Entente in 1934. Its principal purposes were coordination of joint foreign policy and mutual international diplomatic support; it was not a military alliance. [cite book |first=Anatol |last=Lieven |title=The Baltic Revolution: Estonia, Latvia, Lithuania and the Path to Independence |publisher=Yale University Press |year=1994 |pages=77 | isbn=0-300-06078-5 | url=http://books.google.com/books?id=iz3NACNOpCAC&pg=PA77&sig=5t095lNcZKErHaky6yWtjzPwhH4] In Latvian and Estonian opinion, the Polish–Lithuanian dispute over Vilnius was outside the scope of the Entente, but they wished for a resolution, considering the conflict detrimental to the stability of the region. Latvia attempted to persuade Estonia to exert mutual pressure on Lithuania for a speedy acceptance of the ultimatum. This reaction from an ally was unexpected.

Acceptance

President Smetona held a government meeting late on the night of March 18 to decide whether or not to accept the ultimatum. Lithuania clearly lacked international support and the demand was rather tame. A refusal would have cast Lithuania in an unfavorable light as an unreasonable disputant that had irrationally rejected peaceful diplomatic relations for eighteen years. [cite journal| journal=New York Times |title=Paris urging Kaunas to Yield to Warsaw |date=1939-03-19 |pages=2] Lithuanian diplomats were divided on the issue, while popular opinion was strongly against accepting the ultimatum.

"Mourning of Vilnius Day" (October 9, when Żeligowski invaded Lithuania and captured Vilnius), had become an annual event, and the largest social organization in interwar Lithuania was the League for the Liberation of Vilnius (Vilniaus vadavimo sąjunga, or VVS), with some 25,000 members. Passionate feelings about Vilnius were expressed in a popular slogan "Mes be Vilniaus nenurimsim" (we will not rest without Vilnius), [cite book |first=Alfred Erich |last=Senn |title= Lithuania 1940: Revolution from Above | pages=52 | publisher= Rodopi | year=2007 | url= http://books.google.com/books?id=prqkNTCqa9cC&pg=PA52&sig=H9QfXGaJpeUjBn-_5vFg8aNiRQo |isbn= 9-042-02225-6] part of a poem by Petras Vaičiūnas.

President Smetona received memoranda from nine nationalistic organizations urging the government to reject the ultimatum. However, a decisive comment was made by General Stasys Raštikis, the commander of the Lithuanian army: He testified that a military victory over Poland was impossible and argued for a peaceful resolution. The government's decision was confirmed by the Fourth Seimas with minimal discussion. On March 19 Dailidė relayed acceptance of the ultimatum to the Poles, who gave a 12-hour extension to decide on the ultimatum as a show of good faith.

Aftermath

The ultimatum contributed to the general atmosphere of tension and fear in Europe. It relieved some of the pressure on Germany that had arisen in the aftermath of the Anschluss and tested Russia's willingness to defend its interests in Eastern Europe.cite journal |journal=New York Times |title= Nazis are Pleased with Polish "Peace" |date=1939-03-20 |pages=34] Fears were expressed, both in Lithuania and abroad, that the establishment of diplomatic relations was not the only goal of Warsaw and that more far-reaching ultimata might follow. [cite journal |journal=New York Times |date=1939-03-20 |first=Clarence K. |last=Streit |title=Geneva's Anxiety on Poles Persists |pages=34] Speculations arose that Poland might seek to resurrect the Polish–Lithuanian Commonwealth, using Germany's annexation of Austria as a precedent. Poland announced that it planned to create a neutral bloc comprising Poland, Lithuania, Latvia, Estonia, and Romania to counter both fascism and communism. It stated that it had no wish to incorporate Lithuanian territories and maintained that the bloc would be formed on the basis of bilateral non-aggression and economic treaties. [cite journal|journal=New York Times |title=Envoy Says Poland Plans Neutral Bloc |date=1939-03-22 |pages=1, 12] According to the "New York Times", the impact of the ultimatum was felt on Wall Street; on March 17 the foreign currency and bond markets sagged, in some cases reaching the lowest points seen in several years. [cite journal | journal=New York Times |date=1939-03-18 |title=Wall St. Reflects Turmoil in Europe |pages=4] These markets recovered on March 19 after the ultimatum was accepted. [cite journal| journal=New York Times | title=Bond Prices Rise on a Broad Front |date=1939-03-20 |pages=52]

The acceptance triggered a government crisis in Lithuania: on March 24 Prime Minister Juozas Tūbelis, who held uncompromising positions over Vilnius and at the time of the ultimatum was undergoing medical treatment in Switzerland, stepped down.lt icon cite book |title=Lietuvos istorija 11–12 klasėms | first=Rūstis |last=Kamuntavičius |coauthors=Vaida Kamuntavičienė, Remigijus Civinskas, Kastytis Antanaitis |year=2001 |publisher=Vaga |location=Vilnius |isbn=5-415-01502-7 |pages=302–303] His successor, Vladas Mironas, who was in favor of normalizing relations with Poland, assembled a new cabinet of ministers. Despite increasing pressure to form a broader coalition, the new cabinet was composed solely of members of the Lithuanian Nationalists Union. The unconditional acceptance hurt Lithuanian pride and damaged the reputation of the party. The suppressed opposition used this damage as an opportunity to renew its activities and formed a group called "Ašis" (Axis). In Poland the acceptance was greeted with enthusiasm, described as a "great bloodless victory",cite journal |journal=New York Times |first=Jerzy |last=Shapiro |title=Warsaw, Pleased with Results, Now Would Form a Baltic Entente |date=1939-03-20 |pages= 1, 33] and celebrated by a military march in Vilnius. [cite journal |journal=New York Times |first=Jerzy |last=Shapiro |title=Poland Calls Back Army on Frontier; Talks Will Begin |date=1939-03-21 |pages=1, 4]

A few days after the ultimatum, both Lithuania and Poland named their ambassadors. Kazys Škirpa was sent to Warsaw, and Franciszek Charwat was sent to Kaunas before March 31, the deadline indicated in the ultimatum. [cite journal |journal=New York Times |date=1939-04-01 |title=Poland Welcomes Envoy |pages=11] Negotiations over practical matters began on March 25 in Augustów, and by June three agreements covering rail transit, mail service, and river navigation had been concluded. The railroad, torn apart for several kilometers at the border, was repaired. A customs post was established in Vievis, and consulates were opened in Klaipėda and Vilnius. Lithuania closed the League for the Liberation of Vilnius and the Vilnius Foundation; the latter organization had given financial support to Lithuanian activities in the Vilnius Region. [cite book | last=Eidintas | first=Alfonsas | coauthors=Vytautas Žalys, Alfred Erich Senn | editor=Ed. Edvardas Tuskenis | title=Lithuania in European Politics: The Years of the First Republic, 1918-1940 | edition=Paperback | year=1999 | month=September | publisher=St. Martin's Press | location=New York | isbn=0-312-22458-3 | pages=178] Nevertheless, Lithuania continued to claim Vilnius as its "de jure" capital. In May 1938 a new constitution was adopted, which echoed the previous constitution's statement that Vilnius was the permanent capital of Lithuania and that Kaunas was merely a temporary capital. Poland continued to suppress Lithuanian organizations in Vilnius.

A thaw in Polish–Lithuanian relations began in spring 1939. After the German–Czech and German–Lithuanian crises, Poland made more active efforts to ensure Lithuania's assistance, or at least neutrality, in the event of a war with Nazi Germany. Lithuanian General Stasys Raštikis and Polish Foreign Minister Józef Beck made high-profile visits to each other's countries. Poland improved the conditions of Lithuanians in the Vilnius Region. However, Lithuania did not believe that Poland and its western allies were strong enough to resist Germany and Russia. When Germany invaded Poland in September 1939, Lithuania maintained a policy of strict neutrality, refusing repeated German offers for a joint attack on Poland to capture Vilnius. [cite book | last=Eidintas | first=Alfonsas | coauthors=Vytautas Žalys, Alfred Erich Senn | editor=Ed.

Neither country was aware at the time of the secret protocols of the Molotov-Ribbentrop Pact, signed in August 1939, in which Germany and Russia agreed to divide the region into their spheres of influence.
