Overview
The Tacna Province was a territorial division of Chile that existed between 1884 and 1929. It was ceded by the Treaty of Ancón in 1883 and placed under military administration, and then created on the 31st of October 1884, incorporating the former Peruvian provinces of Tacna and Arica of the also former Tacna Department, as well as a contested claim over Tarata, and was returned to Peru at midnight on the 28th of August 1929, under the terms agreed upon in the Treaty of Lima of the same year.
History
The province was first established on October 31, 1883, by a law promulgated by President Domingo Santa María which defined its limits as the Sama River to the north, the Quebrada de Camarones to the south, the Andes mountain range to the east, and the Pacific Ocean to the west. This was under the conditions of Treaty of Ancón, by means of which Chile achieved dominion over the Tarapacá Department, and possession of the provinces of Tacna and Arica for a decade, after which a plebiscite was to be held in 1894 to determine the region's sovereignty, however, it was never carried out. The provisional legal organization would end up working for 50 years, until 1929. During its early years, resistance was at its peak, with some Peruvian military personnel organizing guerrillas, such as Gregorio Albarracín's, of about a hundred men, which were defeated in battle in 1882, with Albarracín and his son being killed in action.
On December 26, 1908, half of Arica, then in the Province of Tacna, was destroyed by an earthquake. The city, as well as the region, were similarly affected by the much stronger earthquake in Valparaíso that happened just a couple of months prior, as well as its aftershocks.
