What notable protest occurred in Langa, near Cape Town, during the Apartheid era?

The protest that occurred in Langa, near Cape Town, during the Apartheid era, which involved a significant turnout of 20,000 participants and resulted in casualties, is indeed a notable event in the history of anti-Apartheid activism. This protest was organized by the Pan Africanist Congress (PAC) and is part of the broader context of resistance against the oppressive laws and practices of the Apartheid regime.

The mass mobilization reflected the heightened frustration and determination among South Africans, particularly within the black community, to challenge the injustices they faced. The fact that the protest resulted in casualties underscores the violent response often faced by activists during this period, highlighting the risks involved in standing against governmental oppression.

Other protest options mentioned, while relevant to the struggles of the time, do not capture the specific importance of the Langa event characterized by both its scale and tragic outcomes. Protests against laws like the Bantu Education Act or the Prohibition of Mixed Marriages Act were undoubtedly significant in their own right but did not manifest in the same way at Langa. This specific protest not only demonstrated mass resistance but also illuminated the broader conflict and urgency of the fight against Apartheid, marking it as a defining moment in South Africa's history.
