When Nelson Mandela received the Nobel Peace Prize, he gave a speech in which he noted the contributions of Martin Luther King Jr. Here are some words of his speech:

"...It will not be presumptuous of us if we also add, among our predecessors, the name of another outstanding Nobel Peace Prize winner, the late African-American statesman and internationalist, the Rev Martin Luther King Jr. He, too, grappled with and died in the effort to make a contribution to the just solution of the same great issues of the day which we had to face as South Africans. We speak here of the challenge of the dichotomies of war and peace, violence and non-violence, racism and human dignity, oppression and repression and liberty and human rights, poverty and freedom from want."

Nelson MAndela seems to have changed his viewpoint the way to achieve change. He went from someone who supported violence to achieve change to someone that, like Martin Luther King Jr, believe in Non violence

1.What is the closest reason of why Nelson Mandela changed his way of thinking?
Because he was in jail for 27 years so he had time to think about what's wrong and what's right. He thought of Martin Luther King Jr did and that he did what's right

I agree.

The closest reason for why Nelson Mandela changed his way of thinking is because he was imprisoned for 27 years, which gave him ample time to reflect on what is right and wrong. During this time, he studied the philosophy and actions of Martin Luther King Jr. and came to believe in the power of non-violence as a means to achieve change. Mandela saw the efforts and sacrifices made by King in the struggle for civil rights in the United States, which inspired him to adopt a similar approach in the fight against apartheid in South Africa.

While Nelson Mandela's 27 years in prison did provide him with ample time for reflection, there were several other factors that contributed to his change in thinking and approach towards achieving change. One significant factor was his exposure to African-American Civil Rights leaders and activists during his time in prison. Mandela engaged in intellectual and political discussions with fellow prisoners, including those who were influenced by the nonviolent philosophy of Martin Luther King Jr.

Another reason for Mandela's change in viewpoint was the realization that violent resistance had limited success in South Africa. The African National Congress (ANC), which Mandela was a part of, initially advocated for armed resistance against the apartheid regime. However, the government's repression and the lack of substantial progress made Mandela recognize the need for alternative strategies.

Additionally, Mandela's personal growth and transformation can also be attributed to his commitment to reconciliation and the pursuit of a peaceful future for South Africa. After his release from prison, Mandela sought to bridge the divide between different racial and ethnic groups and build a democratic and inclusive society.

Overall, Mandela's change in thinking can be attributed to a combination of personal reflection, exposure to different ideas and philosophies, and the practical realization that nonviolent resistance and reconciliation offered a more effective path towards achieving lasting change in South Africa.
