Question: the Klaipėda Revolt of the Directorate of the Klaipėda Region took place at the north of which river?
Context: The Directorate of the Klaipėda Region (German: "Landesdirektorium" ; Lithuanian: "Klaipėdos krašto direktorija" ) was the main governing institution (executive branch) in the Klaipėda Region (Memel Territory) from February 1920 to March 1939.  It was established by local German political parties to govern the region between the signing of the Treaty of Versailles and establishment of French provision administration.  Instead of replacing it, the French legitimized the Directorate.  It mainly represented German interests and supported the idea of leaving the region as a free city, similar to the Free City of Danzig.  Dismayed Lithuanian government and Prussian Lithuanian activists, who campaigned for incorporation into Lithuania, organized the Klaipėda Revolt in January 1923.  The revolt was staged as a popular uprising against the unbearable oppression by the German Directorate.  The revolt was successful and the region was incorporated into Lithuania as an autonomous region, governed by the Klaipėda Convention of May 1924. 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.  During the staged Klaipėda Revolt of 1923, he headed the pro-Lithuanian government of the region.  For his anti-German activities, he was persecuted by the Nazis during World War II.  He survived the Mauthausen-Gusen and Dachau concentration camps.  After the war he remained in Germany and rejoined various Lithuanian organizations.  He was awarded the Order of Vytautas the Great and Order of the Lithuanian Grand Duke Gediminas. Bullfighting was banned in the Spanish autonomous community of Catalonia by a vote of the Catalan Parliament in July 2010.  The ban came into effect on 1 January 2012.  The last bullfight in the region took place in Barcelona in September 2011. The Klaipėda Revolt took place in January 1923 in the Klaipėda Region (Memel Territory, Memelland).  The region, located north of the Neman River, was detached from East Prussia, Germany by the Treaty of Versailles and became a mandate of the League of Nations.  It was placed under provisional French administration until a more permanent solution could be worked out.  Lithuania wanted to unite with the region (part of Lithuania Minor) due to its large Lithuanian-speaking minority of Prussian Lithuanians and major port of Klaipėda (Memel) – the only viable access to the Baltic Sea for Lithuania.  As the Conference of Ambassadors favored leaving the region as a free city, similar to the Free City of Danzig, the Lithuanians organized and staged a revolt. Prussia (Old Prussian: "Prūsa", German: "Preußen" , Lithuanian: "Prūsija" , Polish: "Prusy" ) is a historical region stretching from Gdańsk Bay to the end of Curonian Spit on the southeastern coast of the Baltic Sea, and extending inland as far as Masuria.  The territory and inhabitants were described by Tacitus in Germania in AD 98, where Suebi, Goths and other Germanic people lived on both sides of the Vistula River, adjacent to Aesti (further east).  About 800–900 years later the Aesti were named Old Prussians, who since AD 997 repeatedly successfully defended against take-over attempt by the newly created Duchy of the Polans.  The territory of the Old Prussians and neighboring Couronians and Livonians was unified politically in the 1230s as the Teutonic Order State.  Prussia was politically divided in the period 1466-1772, with western Prussia under protection of the crown of Poland-Lithuania and eastern Prussia a Polish fief until 1660.  The unity of both parts of Prussia remained preserved by retaining its borders, citizenship and authonomy until western and eastern Prussia were also politically re-united under the Kingdom of Prussia.  It is famous for many lakes, as well as forests and hills.  Since the military conquest by the Soviet Army in 1945 and the expulsion of the inhabitants it divided between northern Poland (most of the Warmian-Masurian Voivodeship), Russia's Kaliningrad exclave, and southwestern Lithuania (Klaipėda Region).  The former German state of Prussia (1701–1947) derived its name from the region. 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.  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. Group D of the EuroBasket 2011 took place between August 31 and September 5, 2011.
