In the 1920s and 1930s, Vienna also became a bastion of socialism and was nicknamed “Red Vienna.” At the time, the city was ruled by the Socialist Party of Austria, which implemented a 65.000-unit municipal housing program, as well as a program to establish urban green spaces and introduced education reform. At the time, the Werkbund housing development was established, where workers did not have to nestle in cloisters without windows or running water.
