Antanas Merkys, Lithuanian lawyer and politician, 14th Prime Minister of Lithuania (born 1888)

Antanas Merkys was the last Prime Minister of independent Lithuania, serving from November 1939 to June 1940. When the Soviet Union presented an ultimatum to Lithuania demanding that it accept a Soviet garrison, President Antanas Smetona fled the country leaving Merkys as acting president. Merkys ostensibly cooperated with the Soviets, and illegally took over the presidency in his own right. After three days, Merkys handed power to Justas Paleckis, who formed the People's Government of Lithuania. When Merkys attempted to flee the country, he was captured and deported to the interior of Russia, where he died in 1955.

The prime minister of Lithuania is the head of government of Lithuania. The prime minister is appointed by the president with the assent of the Lithuanian parliament, the Seimas. The modern office of prime minister was established in 1990, when Lithuania declared its independence, although the official title was "Chairperson of the Council of Ministers" until 25 November 1992.
