ANC Youth League president Julius Malema is one of Africa's 10 most powerful young men, according to a list compiled by business magazine Forbes.
"The ANCYL wields enormous power in South African politics, and played a pivotal role in the election of incumbent president, Jacob Zuma, during the 2009 presidential elections," according to the magazine's website.
"Malema, its leader, remains one of the country's most divisive and polarising figures, frequently stirring controversy for his inflammatory rhetoric and racial slurs."
Three other South African men made the top 10 list -- billionaire Mark Shuttleworth, advocate Euvin Naidoo and Chief Executive, Corporate and Investment Banking at the Standard Bank Group David Munro.
Shuttleworth founded Ubuntu, a computer operating system distributed as free open source software. He also set up the Shuttleworth Foundation, a trust that funds individuals actively engaged in social change projects.
Naidoo is president of the SA Chamber of Commerce in America and "one of the most renowned advocates for western investments in Africa", according to Forbes.
Munro, 38, was selected by the World Economic Forum as the 2009 Young Global Leader.
Democratic Republic of Congo president Joseph Kabila and Madagascar president Andry Rajoelina are also on the list.
Five South African women made the magazine's "20 Youngest Power Women in Africa" list -- former Mvelaphanda Group CEO Yolanda Cuba, media mogul Khanyi Ndhlomo, Shanduka Group CEO Phuti Malabie, entrepreneur Lisa Kropman and Ernst & Young senior partner Jonitha Gugu Msibi.
The Mvelaphanda Group is a conglomerate listed on the Johannesburg Stock Exchange.
"In 2008, the Wall Street Journal named Phuti as one of 50 women in the world to watch," Forbes said.
Shanduka is listed as one of South Africa's largest African, black-owned and managed investment holding companies.
Kropman is the founder of Business Place, a group of business centres that support black entrepreneurs in Southern Africa.
Forbes said Msibi served as a public sector and government leader in Africa.
"She is a key adviser to several government leaders in Africa, and was named a Young Global Leader by the World Economic Forum in 2011."
