"Senzeni Na?" (also spelled Senzenina, English: What Have We Done?) is a South African anti‐apartheid folk song. It is a Xhosa struggle song, and 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 wrote a song by the same title, "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.
