Putumayo genocide
Putumayo genocide is the name for a number of systematic enslavements and killings, done by the Peruvian Amazon Company. These events happened between  1879 and 1912. In the late 19th century, rubber was discovered in the Amazon Basin. The Peruvian Amazon Comany was responsible for harvesting the rubber. When they did,  they forced people to work like slaves. Estimates are, that they killed between 40.000 and 250.000 indigenous people. Most of it happened in the area between Río Putumayo and Japurá River, between 1879 and 1912. Today, the area is on the border between Colombia and Peru.
