Today marks the 21st anniversary of the first democratic election in South Africa in which black people were allowed to vote. It is now a national holiday called “Freedom Day.”

Here are some things you might not have known about that election.

First: It was the end of the four-year process that ended Apartheid, which included the release of Nelson Mandela from prison in 1990.

Second: The African National Congress won a landslide victory, taking 62 percent of the vote, and winning majorities in seven of nine provinces.

Third: The first act of the National assembly was to select Mandela as president, South Africa’s first black head of state. He served in that capacity until 1999.

Our question: What was the name of the prison in which Nelson Mandela was held between 1964 and 1982?
