Crimea votes in a controversial referendum to secede from Ukraine to join Russia.

Crimea is a peninsula in Eastern Europe, on the northern coast of the Black Sea, almost entirely surrounded by the Black Sea and the smaller Sea of Azov. The Isthmus of Perekop connects the peninsula to Kherson Oblast in mainland Ukraine. To the east, the Crimean Bridge, constructed in 2018, spans the Strait of Kerch, linking the peninsula with Krasnodar Krai in Russia. The Arabat Spit, located to the northeast, is a narrow strip of land that separates the Syvash lagoons from the Sea of Azov. Across the Black Sea to the west lies Romania and to the south is Turkey. The population is 2.4 million, and the largest city is Sevastopol. The region, internationally recognized as part of Ukraine, has been under Russian occupation since 2014.

The Crimean status referendum of 2014 was a disputed referendum on March 16, 2014, concerning the status of Crimea that was conducted in the Autonomous Republic of Crimea and the city of Sevastopol after Russian forces seized control of Crimea.
