intained an armory in Magyaróvár. As a consequence of the Treaty of Trianon, most of Moson county was lost to non-Hungarian lands and all signs of the Hapsburg rule were destroyed. What followed was another stretch of peace, during which time Moson and Magyaróvár were administratively unified as Mosonmagyaróvár. However, cultural differences and even rivalry would persist until the later 1900s. During the Second World War, unemployment plummeted and the town's industry prospered. The town did not suffer much damage during the war; in 1946, its significant German population was deported. In 1948, bus services were created. During the later 1940s most of the town's institutions were nationalized by the communist regime. As many as 50 protesting civilians were killed during the revolution of '56, and the town had a slow time recovering. During the communist years, a new "town center" was developed between the existing Medieval centers of Moson and Magyaróvár, and there was significant development, including the opening of a university, new schools, and other public projects.
After the rise of the capitalist regime in 1989, the Young Democrats controlled the city government for a few years, increasing tourism and making developments to the gas and sewage infrastructure. Notably, the pianist school was reopened. Since 1994, the socialists have been in power in Mosonmagyaróvár, but it is likely that this will change in the upcoming 2010 elections
