What freedom was taken away from Nelson Mandela?

Nelson Mandela was deprived of his freedom when he was imprisoned for 27 years due to his anti-apartheid activism in South Africa. Convicted of sabotage and conspiracy to overthrow the government, he was held in harsh conditions that severely restricted his movement and communication. This imprisonment symbolized the broader oppression faced by Black South Africans under apartheid, as Mandela became a global figure representing the struggle for freedom and equality. His eventual release in 1990 marked a significant turning point in South Africa's fight against apartheid.
