The Russo-Ukrainian War is an ongoing international conflict between Russia, alongside Russian-backed separatists, and Ukraine, which began in February 2014. Following Ukraine's Revolution of Dignity, Russia annexed Crimea from Ukraine and supported pro-Russian separatists fighting the Ukrainian military in the Donbas war. The first eight years of conflict also included naval incidents, cyberwarfare, and heightened political tensions. In February 2022, Russia launched a full-scale invasion of Ukraine.
In early 2014, the Euromaidan protests led to the Revolution of Dignity and the ousting of Ukraine's pro-Russian president Viktor Yanukovych. Shortly after, pro-Russian unrest erupted in eastern and southern Ukraine. Simultaneously, unmarked Russian troops moved into Ukraine's Crimea and took over government buildings, strategic sites and infrastructure. Russia soon annexed Crimea after a highly-disputed referendum. In April 2014, armed pro-Russian separatists seized government buildings in Ukraine's eastern Donbas region and proclaimed the Donetsk People's Republic (DPR) and Luhansk People's Republic (LPR) as independent states, starting the Donbas war. The separatists received considerable but covert support from Russia, and Ukrainian attempts to fully retake separatist-held areas failed. Although Russia denied involvement, Russian troops took part in the fighting. In February 2015, Russia and Ukraine signed the Minsk II agreements to end the conflict, but the agreements were never fully implemented in the years that followed. The Donbas war settled into a violent but static conflict between Ukraine and Russian proxies, with many brief ceasefires but no lasting peace and few changes in territorial control.
Beginning in 2021, Russia built up a large military presence near its border with Ukraine, including within neighbouring Belarus. Russian officials repeatedly denied plans to attack Ukraine. Russian president Vladimir Putin criticized the enlargement of NATO and demanded that Ukraine be barred from ever joining the military alliance.

Luhansk (luːˈhænsk, -ˈhɑːn-; Луганськ, lʊˈɦɑnjsjk), also known as Lugansk (-ˈɡæn-, -ˈɡɑːn-; Луганск, lʊˈɡansk), is a city in the Donbas region, eastern Ukraine. As of 2022, the population was estimated to be making Luhansk the 12th-largest city in Ukraine. Luhansk served as the administrative center of Luhansk Oblast, before pro-Russian separatists seized control of the city in 2014 and made it the capital of the self-proclaimed Luhansk People's Republic.
The Orange Revolution (Помаранчева революція) was a series of protests and political events that took place in Ukraine from late November 2004 to January 2005, in the immediate aftermath of the run-off vote of the 2004 Ukrainian presidential election, which was claimed to be marred by massive corruption, voter intimidation and electoral fraud. Kyiv, the Ukrainian capital, was the focal point of the movement's campaign of civil resistance, with thousands of protesters demonstrating daily.
Russian oligarchs (oligarkhi) are business oligarchs of the former Soviet republics who rapidly accumulated wealth in the 1990s via the Russian privatisation that followed the dissolution of the Soviet Union. The failing Soviet state left the ownership of state assets contested, which allowed for informal deals with former USSR officials (mostly in Russia and Ukraine) as a means to acquire state property. The Russian oligarchs emerged as business entrepreneurs under Mikhail Gorbachev (General Secretary 1985–1991) during his period of market liberalization.
