50th Anniversary Rally in
Kalnai Park, Vilnius, Lithuania, 1989. in his cabinet soon after his election as the Chairman of the Supreme Council of Lithuania – Reconstituent Seimas in 1990 Landsbergis entered politics, in 1988, as one of the founders of
Sąjūdis, the Lithuanian pro-independence political movement. In the
1989 elections to the Congress of People's Deputies of the Soviet Union, Landsbergis was elected as one of the People's Deputies from Lithuanian SSR. After Sąjūdis' victory in the
1990 elections, he became the Chairman of the
Supreme Council of Lithuania. On 11 March 1990, he headed the Parliamentary session during which the restoration of Lithuanian independence from the Soviet Union
was declared. Lithuania became the first
Soviet Republic to do so. According to the
Temporary Primary Law (
de facto temporary Constitution, until the permanent Constitution comes to power) of Lithuania, Landsbergis was both: the highest officer of State and the
Speaker of the Parliament. He held this post from March 1990 until the
next elections in November 1992. The Soviet Union attempted to stifle this activity by economic blockade in 1990, but it failed, and other Soviet Republics soon followed suit and declared their independence from Moscow as well. He was also extremely dubious of the view that
Mikhail Gorbachev was trying to liberalize the Soviet Union and that Lithuania should not prevent him from doing so. Landsbergis also played a crucial role during the
confrontation between the Lithuanian independence movement and Soviet armed forces in January 1991. Iceland was the first state that officially recognized the restoration of Lithuanian independence; Landsbergis was somewhat critical of certain Western powers (such as the United States and United Kingdom) for not showing enough support in Lithuania's bid to restore its independence after more than 40 years of
Soviet occupation, although he did accept the recommendation from his government that the newly independent Lithuania immediately seek to establish full diplomatic relations with the UK and US. In 1993, Landsbergis led much of Sąjūdis into a new political party, the
Homeland Union (
Tėvynės Sąjunga). It gained a landslide victory in the
1996 parliamentary elections. Landsbergis served as Speaker of the
Seimas from 1996 until 2000. He ran, although unsuccessfully, for president in 1997 (coming up third after receiving 15.9% of the votes). During the runoff, he supported
Valdas Adamkus, who had finished second in the first round. Adamkus eventually became president. In 2004, Landsbergis was elected by Lithuanian voters to the
European Parliament in Brussels (the total number of MEPs from Lithuania in Brussels was 13), and has been returned at every election until 2014. In 2005, Landsbergis became an international patron of the newly formed
Henry Jackson Society. Since 2015, Landsbergis, together with Roswitha Fessler-Ketteler, MEP
Heidi Hautala, Aleksi Malmberg, and
Frank Schwalba-Hoth, is a member of the advisory board of the Caucasian Chamber Orchestra association and its German "Förderverein". ==Attempt to ban Communist and Nazi insignia==
