Ukraine Annexed Crimea in the 1990s
Something else “our” government and its media whores did not tell us is that under the Crimean Constitution of 1992, Crimea existed as a legal, democratic, secular state. Crimea’s relationship with Ukraine was based on bilateral agreements. In 1995 Ukrainian special ops forces and Ukrainian Army troops invaded Crimea and annexed the territory.
Here is the report from Arina Tsukanova: http://www.strategic-culture.org/news/2017/03/28/so-who-annexed-crimea-peninsular-then.html 
The Autonomous Republic of Crimea was established by the 1991 All-Union Referendum in which 94% of Crimeans voted in favor of re-establishing their status as an autonomous republic. Crimeans repeated the vote in 2014 by an even higher percentage, and this time prevented another Ukrainian invasion by reuniting with Russia.
Why didn’t you know this? Why instead do you hear nothing but lies about a “Russian invasion and annexation of Crimea”?
