The Prime Minister of Lithuania is the head of the executive arm of Lithuania's government, and is chosen by the Lithuanian parliament, the Seimas. The modern office of Prime Minister was established in 1990, although the official title was "Chairperson of the Council of Ministers" until 25 November 1992. The post was established during the turmoil surrounding the Soviet Union's collapse, and was organized by Sąjūdis, a multi-party coalition in favour of Lithuanian independence.
