Occupation of the Ruhr
On 9 January 1923, three years after the Versailles Treaty had become effective, Lithuania occupied the territory during the Klaipėda Revolt, mainly by militia that had entered the region from Lithuania. France at the same time had started the [[Occupation of the Ruhr]] in Germany, and the French administration in Memel did not take any significant counteractive measures against the rebels. On 19 January, the territory was annexed by Lithuania, and the "fait accompli" was eventually confirmed by the Council of Ambassadors in 1924.
