 National minorities were recognized by the 1923 Constitution of Romania and supported by laws; they were represented in Parliament and several of them created political parties, although a unique standing of minorities with autonomy on a wide basis, provided for at the assembly of Transylvanian Romanians on 1 December 1918, was not fulfilled.Two periods can be identified in Romania between the two World Wars.From 1918 to 1938, Romania was a monarchy whose liberal Constitution was seldom respected in practice, but one facing the rise of the nationalist, anti-semitic parties, particularly Iron Guard, which won about 15% of the votes in the general elections of 1937.
