"Power to the people" is a cultural expression and political slogan that has been used in a wide variety of contexts.
A popular variation of the slogan is "Power to the Poor People!" Amongst others, the South African social movement the Western Cape Anti-Eviction Campaign uses the slogan to express the need for poor people to control their own movements rather than have wealthy donors or NGOs control or speak for them. The divide between South Africa's independent social movements and many leftist and vanguard organizations in South Africa has become a point of contention.
The South African slogan "Amandla Ngawethu" or "Amandla Awethu" is also a popular variation of the Power to the People. It literally means "The power is ours" but is used in a similar way as "Power to the People". It is often used in a call and response format, with the speaker shouting "Amandla" and the crowd replying "Awethu".
