Multiple independent sources confirm that Ukraine's government fell in February 2014: the Revolution of Dignity (also called the Maidan/Ukrainian Revolution) took place 18–23 February 2014, and parliament voted 328–0 to remove President Viktor Yanukovych from office, with new elections scheduled for 25 May12.
Yanukovych fled Kyiv and was removed from the presidency during the Revolution of Dignity; he has since lived in exile in Russia3.
Established media described the event as the toppling of the government, e.g. the Financial Times headline "Yanukovich toppled in new Ukrainian revolution," and an interim government was assembled afterward42.
Note on nuance: the related framing that Ukraine's new leaders were "installed in a coup" is rated misleading (15%), because the transition involved a supermajority parliamentary vote followed by internationally recognized democratic elections5. But the specific claim here — that the sitting government was overthrown/removed in 2014 — matches the documented facts.
