Africa is celebrating Nelson Mandela's 100th birthday

Former president Barack Obama addresses inequality and other issues at the 2018 Nelson Mandela Annual Lecture in his first major speech since leaving office

"Look around. Strongman politics are ascendant suddenly, whereby elections and some pretense of democracy are maintained but those in power seek to undermine every institution or norm that gives democracy meaning", Obama said Tuesday during a speech in South Africa honoring Nelson Mandela.

Mandela spent 27 years behind bars to fight against White Supremacy in South Africa.

Although Wakoli may not be a household name, Obama distinguished her to be "among the 200 people from the African continent who are striving to make changes in their communities and reflecting Mandela's values and are poised to lead the way". What's wrong with us?' I mean, we're violent.

Nelson Mandela's profound impact on the people and country of South Africa will never be forgotten, and his influence as South African President between 1994 and 1999 and a revolutionary anti-apartheid figure will always be prevalent in South African and world history. They highlighted various aspects of Nelson Mandela's life and struggle.

Newly released U.S. intelligence documents showed that the Federal Bureau of Investigation continued to investigate South Africa's anti-apartheid icon Nelson Mandela as a potential "communist menace" even after his release from prison in 1990, a Washington-based group which sued to obtain the papers said.

"I really appreciate it that Obama spoke out against Trump", 25-year-old management consultant Karabo Tima told AFP after attending the speech.

But Obama also made remarks that can only be seen as a condemnation of intolerant leftists who shut down speakers on college campuses because they find their views offensive.

With a thinly veiled reference to his successor Donald Trump, Obama opened by remarking on the "strange and uncertain times we are in...and they are very odd". After Obama became president he sent a copy of the photo to Mandela, who kept it in his office.

A memorial stone at Westminster Abbey has been dedicated to Nelson Mandela.

Obama is delivering a speech to mark the 100th anniversary of Mandela's birth. I believe in a vision shared by Gandhi and King and Abraham Lincoln.

Mr Obama met young leaders from around Africa to mark the anniversary, a day after he delivered a speech in Johannesburg about Mr Mandela's legacy of tolerance and criticised U.S. president Donald Trump and his policies without mentioning him by name. South African President Cyril Ramaphosa and Mandela's widow Graca Machel joined him for the annual Nelson Mandela Lecture. The year commemorating Mandela's birth will finish with a concert in Johannesburg in December starring Beyonce, Jay-Z, Ed Sheeran, Pharrell Williams and Cassper Nyovest.
