Ukrainian Soviet Socialist Republic
Eventually, after the creation of the Communist Party (Bolshevik) of Ukraine in Moscow, a third Ukrainian Soviet government was formed on 21 December 1919 that initiated new hostilities against Ukrainian nationalists as they lost their military support from the defeated Central Powers. Eventually, the Red Army ended up controlling much of the Ukrainian territory after the Polish-Soviet Peace of Riga. On 30 December 1922, along with the Russian, Byelorussian, and Transcaucasian republics, the Ukrainian SSR was one of the founding members of the Union of Soviet Socialist Republics (USSR).
Ukraine
Following its independence, Ukraine declared itself a neutral state; it formed a limited military partnership with Russia and other CIS countries while also establishing a partnership with NATO in 1994. In 2013, after the government of President Viktor Yanukovych had decided to suspend the Ukraine-European Union Association Agreement and seek closer economic ties with Russia, a several-months-long wave of demonstrations and protests known as the Euromaidan began, which later escalated into the 2014 Ukrainian revolution that led to the overthrow of Yanukovych and the establishment of a new government. These events formed the background for the annexation of Crimea by Russia in March 2014, and the War in Donbass in April 2014. On 1 January 2016, Ukraine applied the economic component of the Deep and Comprehensive Free Trade Area with the European Union.
