Before the arrival of the
Spanish, Monsefú would have been part of the chieftainship of Cinto, with the name of Chuspo, whose main center have been located in the vicinity of San Bartolo hill. The town was founded by the Spanish under the name "San Pedro de Monsefú". In 1578, heavy rains and floods blighted the crops and in 1612, the area was ravaged by a disease. The population was reduced by the disease and survivors after a few years were located in what is now Monsefú. In the early 1880s, the
Chilean Army, under the command of
Patricio Lynch,
occupied the area and its surroundings during the
War of the Pacific, where infrastructure was built by the Chilean authorities for both the locals and the troops' use, with the latter residing in a
barracks. After the war, the town was elevated to city level on October 26, 1888 at the request of deputy Manuel María Izaga, under the presidency of
Andrés Avelino Cáceres. ==Government==
