coup against Achá, leading to Frías' exilement to Europe. In 1870, Frías returned to Bolivia, hoping to establish himself in La Paz and withdraw to private life. However, on November 24, a revolution against Melgarejo was ignited. Frías' home was surrounded by his neighbors, calling him to assume the Prefecture of La Paz.
