Because of Gamarra's non-intervention policy in Bolivia, Blanco Soto and Loayza Pacheco revolted on September 1828, with the latter declaring the independence of the La Paz Department under the name of the Republic of Alto Perú.[1] Despite this limited control, it claimed the entirety of the Bolivian state. This forced the convening of a new assembly that met in the department of Chuquisaca in the Convention of December 1828, composed for the most part of supporters of Gamarra, who appointed Blanco president and the now general Loayza vice president on 26 December.[2]
