Have you read any history?"
300 years before 1956 - in 1656 -- Crimea was part of the Tatar khanate, in fact it was part of the Tatar Khanate until 1783 so your "300 years" statement is flatly WRONG
It was Tatar ruled from the 13th century until 1783 - nearly 500 years which trumps the 170 years of rule from the Kremlin
And then you get the situation after the Tsar lost
It was part of the Ukrainian state from May to June 1918 and was an independent SSR from May 1921 to 30 June 1945. The autonomous republic without its titled nationality was downgraded to an oblast (province) within the Russian SFSR on 30 June 1945
So Crimea was "Russian" only from 1783 to 1918, then from 1945 to 1954 = 144 years
The longest lived population in that area are the Crimean Tatars
And how many years was it Ukrainian?
Sorry cronos, the Crimea was an integral part of Russia from 1783 to 2014, a total of 231 years total. It is nonsensical to argue about the internal political division of territories within the Soviet Union because the Soviet Union was Russia. Furthermore it is part of an ongoing Civil War that is only 10 years old.
You comment like a back-alley attorney.
You’re wrong about the tatars, the greeks were there many centuries longer
