The Parliament of the Klaipėda Region (Chamber of Representatives of the Memel Territory, Lithuanian: Seimelis, German: Landtag) was the parliament of the Klaipėda Region (Memel Territory), an autonomous region of Lithuania. The parliament was established by the Klaipėda Convention of 1924 and the first elections took place in October 1925. In all elections pro-German parties received more than 80% of the vote. The major parties included the Memel Agricultural Party (Memelländische Landwirtschaftspartei or MLP), Memel People's Party (Memelländische Volkspartei or MVP), and Social Democratic Party of the Memel Territory (Sozialdemokratische Partei des Memelgebietes or SPM). The pro-German parliament often clashed with the pro-Lithuanian Klaipėda Directorate (executive branch of local government) and the first three parliaments were dismissed before the end of their full three-year term. The parliament was disbanded after the ultimatum of March 1939 and subsequent Nazi German takeover of the region.
According to the Treaty of Versailles of 1919, the Klaipėda Region (Memel Territory) was detached from East Prussia, German Empire, and placed under temporary administration of the League of Nations. After the Klaipėda Revolt in January 1923, the region was transferred to Lithuania on condition that it would abide by the Klaipėda Convention, signed in May 1924 and fully effective in August 1925. The Convention included the Statute of the Klaipėda Region, which described region's legislative, judicial, administrative, and financial autonomy. The Convention also established the framework of the autonomous institutions – the local parliament and the Klaipėda Directorate (executive branch). The parliament was to be democratically elected for three-year terms by the local inhabitants in the proportion of one representative per 5,000 residents. The parliament confirmed and dismissed the Directorate, appointed by the Governor. The Directorate and the Lithuanian-appointed Governor could dismiss the parliament; in such a case, the new elections had to be called within six weeks. The Governor could veto laws passed by the parliament, but only if they violated the Convention, Constitution of Lithuania, or other international agreements. Of the 165 laws passed between 1925 and 1938, 62 were vetoed. The parliament was in charge of region's education, religious affairs, public health and welfare, local infrastructure, civil, criminal, and economic legislature, finances, court organization, etc.
