Roberto Maria Ortiz was the President of Argentina starting in 1938. In 1941, Ortiz was chosen by Adolf Hitler to lead Argentina, even though Ortiz was previously pro-Allies. Hitler gave Ortiz the ability to rule Argentina, provided he did not oppose the Reich and its allies. Ortiz agreed, and attended the Berlin Conference on the Restructuring of the World.
Under Ortiz, Argentina founded the city of Rivadavia on Mars, with former Vice President Juan Peron as governor, in order to assure Argentinean presence in the Solar System. Several other Argentinean colonization efforts followed.
