In November 2013, a wave of large-scale protests (known as Euromaidan) erupted in response to President Yanukovych's refusal to sign a political association and free trade agreement with the European Union (EU) at a meeting of the Eastern Partnership in Vilnius in Lithuania. These protests continued for months. In February 2014, clashes between the protestors and the Berkut (special riot police) became violent, and resulted in the deaths of nearly 130 people, including 18 police officers. On February 21, an agreement between President Yanukovych and the leaders of the parliamentary opposition was signed that called for early elections and the formation of an interim unity government. The following day, Yanukovych fled from the capital ahead of an impeachment vote. The protesters proceeded to take control of the capital buildings. On the same day, the parliament declared that Yanukovych was relieved of duty in a 328-to-0 vote (out of the Rada’s 450 members).
Yanukovych said that this vote was illegal and possibly coerced, and asked the Russian Federation for assistance. Russia considered the overthrow of Yanukovych to be an illegal coup, and did not recognize the interim government. Widespread protests, both in favor of and against the revolution, occurred in the eastern and southern regions of Ukraine, where Yanukovych previously received strong support in the 2010 presidential election. These protests escalated, resulting in a Russian military intervention and the establishment of the self-proclaimed proto-states Donetsk and Luhansk.
The interim government, led by Arseniy Yatsenyuk, proceeded to sign the EU association agreement. Petro Poroshenko became the president of Ukraine after a landslide victory in the 2014 presidential elections. The new government restored the 2004 amendments to the Ukrainian constitution that were controversially repealed as unconstitutional in 2010 and initiated a large-scale purge of civil servants who were associated with the overthrown regime.
So, again, Putin is to be accepted as the sole arbiter of the internal affairs of Ukraine. Indeed, Ukraine must be seen as a part of Russia, and only Russia. Disagreement with these propositions is to be met with brute force as a matter of "self-defense."
