Question: The Parliament of the Klaipėda Region was disbanded after an ultimated was issued just five days after what?

<P0-S0> 1939 German ultimatum to Lithuania was an oral ultimatum presented to Juozas Urbšys, Foreign Minister of Lithuania, by Joachim von Ribbentrop, Foreign Minister of Nazi Germany, on 20 March 1939. <P0-S1>  The Germans demanded that Lithuania give up the Klaipėda Region (also known as the Memel Territory), which had been detached from Germany after World War I, or the Wehrmacht would invade Lithuania. <P0-S2>  After years of rising tension between Lithuania and Germany, increasing pro-Nazi propaganda in the region, and continued German expansion, the demand was expected. <P0-S3>  The ultimatum was issued just five days after the Nazi occupation of Czechoslovakia. <P0-S4>  The four signatories of the 1924 Klaipėda Convention, which had guaranteed the protection of the "status quo" in the region, did not offer any material assistance. <P0-S5>  The United Kingdom and France followed a policy of appeasement, while Italy and Japan openly supported Germany. <P0-S6>  Lithuania was forced to accept the ultimatum on 22 March. <P0-S7>  For Germany it was the last territorial acquisition before World War II; for Lithuania it was a major downturn in economy and morale; for Europe it was further escalation in pre-war tensions. <SEP> <P1-S0> The Parliament of the Klaipėda Region ("Chamber of Representatives of the Memel Territory", Lithuanian: "Seimelis" ) was the parliament of the Klaipėda Region (Memel Territory), an autonomous region of Lithuania. <P1-S1>  The parliament was established by the Klaipėda Convention of 1924 and the first elections took place in October 1925. <P1-S2>  In all elections pro-German parties received more than 80% of the vote. <P1-S3>  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). <P1-S4>  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. <P1-S5>  The parliament was disbanded after the ultimatum of March 1939 and subsequent Nazi German takeover of the region. <SEP> <P2-S0> Heinrich Buttkereit (1884–1947) was an ethnic German politician in Lithuania. <P2-S1>  Buttkereit was born on April 23, 1884 in Ruß. <P2-S2>  He was a farmer from Ruß. <P2-S3>  In the 1932 election to the parliament of the Klaipėda Region, he stood as candidate number 26 on the list of the Memel Agricultural Party. <P2-S4>  He was not elected in 1932, but on September 13, 1934 he filled one of seats in the assembly that had been left vacant. <P2-S5>  He remained a member of the regional parliament until the 1935 elections. <SEP> <P3-S0> Erdmonas Simonaitis (October 30, 1888 in Juschka-Spötzen (Spiečiai), Province of East Prussia – February 24, 1969 in Weinheim, West Germany) was a Prussian Lithuanian activist particularly active in the Klaipėda Region (Memel Territory) and advocating its union with Lithuania. <P3-S1>  During the staged Klaipėda Revolt of 1923, he headed the pro-Lithuanian government of the region. <P3-S2>  For his anti-German activities, he was persecuted by the Nazis during World War II. <P3-S3>  He survived the Mauthausen-Gusen and Dachau concentration camps. <P3-S4>  After the war he remained in Germany and rejoined various Lithuanian organizations. <P3-S5>  He was awarded the Order of Vytautas the Great and Order of the Lithuanian Grand Duke Gediminas.
