Nelson Mandela faced numerous struggles during his imprisonment, including long isolation from loved ones, harsh living conditions, and psychological pressure. He was often subjected to forced labor and was denied basic rights and privileges. Despite these challenges, Mandela remained committed to his anti-apartheid ideals, using his time to grow politically and intellectually. He also experienced the challenge of maintaining unity among fellow prisoners and the broader African National Congress. Ultimately, his resilience and focus on reconciliation would later play a crucial role in dismantling apartheid.
