Senzeni Na?

“Senzeni Na?” (also spelled Senzenina, English: What Have We Done?) is a South African anti‐apartheid folk song. The Xhosa/Zulu language song is commonly sung at funerals, demonstrations and in churches. Activist Duma Ndlovu compared the influence of “Senzeni Na?” to that of the American protest song, “We Shall Overcome.”

The song has been around at least since the 1950s, and it reached the height of its popularity during the 1980s. The origins of the song are unclear. Zimbabwean poet Albert Nyathi claims to have written “Senzeni Na?” on the day that activist Chris Hani died.

The song was among several songs of a more mournful nature that became popular among anti-apartheid activists in the 1960s. The song repeats the line "What have we done" a number of times, which musician Sibongile Khumalo has described as giving the listener a sense of desolation.

While best known in South Africa, “Senzeni Na?” has gained some popularity overseas. The song was featured in the anti‐apartheid film The Power of One and a recording of the song as sung at the funeral of Steve Biko can be heard at the end of the album version of “Biko” by Peter Gabriel. The music was used for an adaptation of the hymn “When I Survey the Wondrous Cross” by Isaac Watts in the Mennonite Hymnal: A Worship Book.

In Kim Stanley Robinson's Mars Trilogy there is a city called Senzeni Na (founded by the Japanese). Part 7 of the book is also titled "Senzeni Na."
