At the Second Meeting of American Organisations and Movements in Tihuanacu, Bolivia, in 1983, September 5 was officially designated International Indigenous Women’s Day.
Since then, September 5 has been growing in recognition as a major event in Latin America's progressive calendar.
The date was chosen in honour of Bartolina Sisa, an Aymara resistance leader who was brutally executed by royalist forces in La Paz, now the capital of Bolivia, on September 5, 1782.
