What are the Provinces of Argentina?

Argentina is a federal republic of 23 provinces and the Autonomous City of Buenos Aires. Each province has its own constitution, governor and legislature.

• Many provinces are older than Argentina itself.
• After the May Revolution of 1810, the former colonial jurisdictions acted as independent provinces.
• They united as a federation under the 1853 constitution.
• The Chaco and Patagonia were run as national territories until most became provinces in the 1950s.
• The last, Tierra del Fuego, became a province in 1990.
