Government of Juan Manuel de Rosas

Juan Manuel de Rosas was a powerful Argentine politician who governed Buenos Aires province from 1835 to 1852, becoming a symbol of the Federalist movement. His rule is characterized by authoritarianism, where he maintained control through a strong state and a para-military police force. Rosas promoted rural interests and used violence and censorship against opponents, creating a polarized society. He espoused the idea of federalism but often acted to centralize power. His government ended in 1852 after military defeat, leading to the establishment of a more unified Argentine nation under a federal constitution.
