Teachers' League of South Africa

The group, while originally focused on issues surrounding education, became increasingly political in the mid-1940s and started to agitate against apartheid.

TLSA was started in Cape Town in June of 1913 as a group for coloured teachers.

[1][2] One of the founding members was Harold Cressy and the African Political Organization (APO) laid the foundations that allowed TLSA to grow.

[7] In 1934, TLSA changed its constitution so that membership was no longer limited to coloured teachers.

[7][10] As TLSA became more radical, some moderates left in 1944 to form the Teachers' Educational and Professional Association (TEPA).
