Upu, also called Apu-(and Ubi or Upi by some authors), was the region surrounding
Damascusof the 1350 BC Amarna letters. Damascus was named "Dimašqu"/"Dimasqu"/-etc-(for example, "Dimaški"-(see: Niya (kingdom)), in the letter correspondence.
The region is only referenced in three letters, EA 53, 189, and 197 (EA is for 'el
Amarna'). Etakkamaof "Qidšu"-( Kadesh) in the Beqaa-(named the " Amqu") is in partial control, between allegiance to Pharaoh, and conjoining forces with the king of Hatti.
An example of the intrigue is from the last third of EA 53, (entitled: "Of the villain Aitukama"):
:"....:"My lord, if he-(i.e. pharaoh) makes this land a matter of concern to my lord, then may my lord send archers that they may come here. (Only) messengers of my lord have arrived here.:My lord, if
Arsawuyaof Ruhizziand Teuwattiof Lapana remain in "Upu", and Tašša-(Tahash) remains in the [Amqu|Am [q] , my lord should also know about them that "Upu" will not belong to my lord. Daily they write to Aitukama-( Etakkama) and say as follows: "Come, tak [e] "Upu" in its entirety.":My lord, just as Dimaški-(Damascus) in "Upu" (falls) at your feet, so "may" Qatna(fall) at your feet. My lord, one asks for life before my messenger. I do not fear [at al] l in the presence of the archers of my lord, "since" the archers belong to my lord. If he sends (them) to me, they will en [ter] Qatna." -EA 53, ("only" lines 52-70(End)).
The intrigue of the three Amarna letters appears to involve areas to the north and northwest of Damascus, into Lebanon and the Beqaa-(named
And, for example
Tašša, appears to be "Tahash"-Tahaš, named after the biblical 'Tahash' personage; see: Patriarchs (Bible).
