Following the break-up of the Austro-Hungarian Empire in 1918, Moravia became part of Czechoslovakia. As one of the five lands of Czechoslovakia, it had restricted autonomy. In 1928 Moravia ceased to exist as a territorial unity and was merged with Czech Silesia into the Moravian-Silesian Land (yet with the natural dominance of Moravia). By the Munich Agreement (1938), the southwestern and northern peripheries of Moravia, which had a German-speaking majority, were annexed by Nazi Germany, and during the German occupation of Czechoslovakia (1939–1945), the remnant of Moravia was an administrative unit within the Protectorate of Bohemia and Moravia. During the WW II Moravia lost 46,306 Jews according to religion.
