List of constitutions by age

The world's oldest countries based on a continuous form of government, i.e. a national "constitution".

A country is defined by its government, not its borders.

The term "oldest countries" is sometimes used to refer to countries with the oldest "populations", which is unrelated - see Demography.

Years given are when each country's current constitution took effect, unless otherwise noted.

Other constitutions

#Finland, 1906
#Monaco, 1911
#Mexico, 1917
#United Kingdom, 1927, no constitution [The United Kingdom has no codified constitution, but instead relies on traditional customs and separate pieces of constitutional law. The "Act of Union 1800" was enacted in 1801 and created the "United Kingdom of Great Britain and Ireland". However, the "Royal and Parliamentary Titles Act 1927" was a major governmental change that created the current official country name, "United Kingdom of Great Britain and Northern Ireland", after the emergence of the "Irish Free State" (Ireland). Other significant governmental revisions include the "Balfour Declaration of 1926", and the "Statute of Westminster 1931".]
