The Arica Department 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, as one of the three departments of the Tacna Province, 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.
