South Africa's negotiated transition (1990-1994)
After 27 years in prison, Nelson Mandela was released in February 1990 as part of negotiations to end apartheid. The government freed political prisoners as goodwill gestures while talks over a democratic constitution proceeded.
Negotiations nearly collapsed several times over violence and prisoner disputes.
South Africa held its first multiracial elections in April 1994, with Mandela winning the presidency.
Political prisoner releases served as confidence-building measures in a negotiated transition, the same role they play in Venezuela's US-brokered process.
