The most important geopolitical event of 2014 was the acceptance of Crimea into the Russian Federation.
As a result of an Ukraine-wide political crisis and of months-long anti-presidential and anti-government events, an uprising took place in Ukraine. The very first actions of the opposition that came to power in Kiev brought out the protests of the local mostly Russian-speaking population.
Due to the conflict, deep-set antagonism towards the new government had emerged, which led to the acceptance on March 11, 2014, of the Declaration of Independence of the Autonomous
Republic of Crimea and the city of Sevastopol, which proclaimed the temporary status of the Republic of Crimea as an independent state with a republican form of government.
On March 16, 2014, an All-Crimea referendum took place, during which the majority of Crimeans cast their votes for their republic leaving Ukraine and for joining of Crimea and Russia.
On March 18 in Kremlin the Interstate Agreement of the joining of Crimea to Russia with the formation of two new constituent entities of the Federation – the Republic of Crimea and the federal city of Sevastopol – was signed.
