On May 25, 1809, a revolution in Chuquisaca deposed the governor and president of the Royal Audiencia of Charcas, Ramón García de León y Pizarro, and accused him of supporting a Portuguese protectorate under the authority of Charlotte Joaquina. Military command fell to Colonel Juan Antonio Alvarez de Arenales who, due to uncertainty as to who should be in charge of the civilian affairs, also exercised some civil powers. On July 16, in the city of La Paz, a second revolutionary movement led by Colonel Pedro Domingo Murillo forced the governor to resign and replaced him with a Junta, the "Junta Tuitiva de los Derechos del Pueblo" ("Junta, keeper of the rights of the people"), headed by Murillo.
