International Labour Organization

The International Labour Organization adopted the Indigenous and Tribal People’s Convention (ILO Convention No. 169) in 1989, which has been ratified by 20 countries. Convention No. 169 was developed to protect self-identified indigenous people and attempts to address all key aspects of indigenous peoples’ rights. This is a guide to provide governments, indigenous and tribal peoples, and organizations with a tool for implementing indigenous peoples’ rights.
