And how many years was it Ukrainian?
Crimea was :
Tatar for 500 years from 1239 to 1783
Tsardom of Russia for 134 years from 1783 to 1917
NOTE that the USSR explicitly said that it was NOT a successor state to the Tsardom of Russia. Hence it was a completely separate entity.
The Russian federation said that it was/is a successor state to the USSR, so it is NOT a successor state to the Tsardom of Russia.
A separate SSR for 33 years from 1922 to 1945
Ukrainian for 60 years from 1954 to 2014
Russian Federation for 10 years
Hence it has been Ukrainian for the second longest after it has been Tatar Khanate.
the least amount of time it has been Russian
