Edited sentence: After the Communist Party seized power in Czechoslovakia in February 1948, the city became part of the Eastern Bloc, and hundreds of citizens were expelled during the communist repression of the 1950s, with the aim to replace "reactionary" people with the proletarian class.In 1938 the Nazi leader Adolf Hitler annexed neighbouring Austria in the Anschluss; as part of this Germany annexed the still-independent Petržalka and Devín boroughs on ethnic grounds.This policy was championed by the pro-Nazi wing of the Slovak People's Party, was approved by most of the population, and was not in itself unusual for the city, as Bratislava Jews had been victims of riots and pogroms in 1882, 1848 and earlier.Under the democracy and relative ethnic tolerance of the First Czechoslovak Republic the number of declared Slovaks doubled and Czech population increased, while German and especially Hungarian population fell considerably in the city, but the rise of fascist ideas in the late 1930s increased ethnic tensions
