"Chiquitos" is the colonial name for what is now essentially five of the six provinces that make up the Chiquitania, a region in Bolivia's Santa Cruz department. "Chiquitos" refers to a region, not a tribe. One of the many tribes inhabiting Chiquitos were the Chiquitano.
The name Chiquitos means "little ones" in Spanish. It was chosen by the Spanish conquistadores, when they found the small doors of the Indian huts in the region. Around 20 ethnic groups live in the Chiquitania.
A notable feature are the 18th century Jesuit reductions and Franciscan settlements scattered throughout the region. Six churches still remain in the zone and were selected in 1990 as UNESCO World Heritage Sites under the name Jesuit Missions of the Chiquitos.
