The Argentine Constitution of 1949 was approved during Juan Domingo Perón's government. This was a major revision of the Constitution of Argentina. Its goal was to modernize and adapt the text to the twentieth century's concepts of democracy, with a bill of social rights, including better working conditions for the working class, right to education, etc. It also allowed for the indefinite reelection of the president.
It was suppressed by Pedro Eugenio Aramburu's coup d'état which led to the so-called Revolución Libertadora.
