CE 466.
On July 21, 1946, anti-government crowds took control of the Plaza Murillo, the site of the Palace of Government, laying siege to it. From within the Palace, Villarroel announced his resignation, but the enraged crowds of teachers, students, and marketplace women seized arms from the arsenal and broke in, after an hour of fighting, assassinating him and various of his aides.
The opposition regained control of the government, keeping it until the Bolivian National Revolution, in 1952.
