Guarantee human rights and liberties

Nelson Mandela worked to end the policies of apartheid in South Africa, which maintained a system of white dominance over blacks in that country.  Mandela eventually became the first black president of South Africa, inaugurated in 1994.  He was awarded the Nobel Peace Prize in 1993.

Aung San Suu Kyi was awarded the Nobel Peace Prize in 1991 for her efforts to bring democracy to Burma, which changed its name to the Union of Myanmar in 1989.  She worked in opposition to the military regime that had controlled the country since 1962.  In 1990, Aung San Suu Kyi's National League for Democracy party won the elections, but the military regime placed she remained under house arrest by the military government from 1989 to 2010.  She has been in the position of First State Counsellor of Myanmar (essentially, prime minister) since 2016.   Aung San Suu Kyi's commitment to human rights and civil liberties has been questioned in recent years because of her lack of intervention in the severe (potentially genocidal) persecution of the Rohingya minority that has been occurring in Myanmar.
