In the late 19th century, the Içá was navigated by the French explorer
Jules Crevaux
Jules Crevaux (1847–1882) was a French doctor, soldier, and explorer. He is known for his multiple explorations into the interior of French Guiana and the Amazon.

These abuses were first publicized in 1909 within the British press by the American engineer Walter Hardenburg, who had been briefly imprisoned by Arana's private police force in 1907 while visiting the region; Hardenburg later published his book ''The Putumayo: The Devil's Paradise'' in 1913.
