History

The area is inhabited by Ticuna Indians. The Magüta Museum in the town is devoted to their culture and language. In 1988 the town was the scene of the murder of 14 Ticunas in a dispute between them and logging interests.^[3]

The town was named after the Brazilian revolutionary Benjamin Constant (1836–1891).
