Barack Hussein Obama II (ⁱ/bəˈrɑːk huːˈseɪn oʊˈbɑːmə/; born August 4, 1961) is the 44th and current President of the United States. He is the first African American to hold the office. In January 2005, Obama was sworn in as a U.S. Senator in the state of Illinois. He would hold this office until November 2008, when he resigned following his victory in the 2008 presidential election.

Born in Honolulu, Hawaii, Obama is a graduate of Columbia University and Harvard Law School, where he was the president of the Harvard Law Review. He was a community organizer in Chicago before earning his law degree. He worked as a civil rights attorney in Chicago and taught constitutional law at the University of Chicago Law School from 1992 to 2004. He served three terms representing the 13th District in the Illinois Senate from 1997 to 2004.

Following an unsuccessful bid against the Democratic incumbent for a seat in the United States House of Representatives in 2000, Obama ran for the United States Senate in 2004. Several events brought him to national attention during the campaign, including his victory in the March 2004 Illinois Democratic primary for the Senate election and his keynote address at the Democratic National Convention in July 2004. He won election to the U.S. Senate in Illinois in November 2004. His presidential campaign began in February 2007, and after a close campaign in the 2008 Democratic Party presidential primaries against Hillary Rodham Clinton, he won his party's nomination. In the 2008 presidential election, he defeated Republican nominee John McCain, and was inaugurated as president on January 20, 2009. Nine months later, Obama was named the 2009 Nobel Peace Prize laureate. In April 2011, he announced that he would be running for re-election in 2012.

Robert Gabriel Mugabe (Shona pronunciation: [muɡaɓe],^{[needs tone]}English: /muːˈɡɑːbiː/ moo-GAH-bee; born 21 February 1924) is the President of Zimbabwe. As one of the leaders of the liberation movement against white-minority rule, he was elected into power in 1980. He served as Prime Minister from 1980 to 1987, and as the first executive head of state since 1987.

Mugabe rose to prominence in the 1960s as the Secretary General of the Zimbabwe African National Union (ZANU) during the conflict against the white-minority rule government of Ian Smith. Mugabe was a political prisoner in Rhodesia for more than 10 years between 1964 and 1974. Upon release with Edgar Tekere, Mugabe left Rhodesia in 1975 to re-join the Zimbabwe Liberation Struggle (Rhodesian Bush War) from bases in Mozambique.

At the end of the war in 1979, Mugabe emerged as a hero in the minds of many Africans. He won the general elections of 1980, the second in which the majority of black Africans participated in large numbers (though the electoral system in Rhodesia had allowed black participation based on qualified franchise). Mugabe then became the first Prime Minister after calling for reconciliation between formerly warring parties, including white Rhodesians and rival political groups.

Meles Zenawi Asres (Ge'ez: መለስ ዜናዊ አስረስ Mäläs Zenawi Äsräs; born 8 May 1955) has been the Prime Minister of Ethiopia since 1995. He was President of Ethiopia from 1991 to 1995. Since 1985, he has been chairman of the Tigrayan Peoples' Liberation Front (TPLF), and he is head of the ruling Ethiopian People's Revolutionary Democratic Front (EPRDF).

Meles was born in Adwa, Tigray in Northern Ethiopia, to an Ethiopian father from Adwa, Ethiopia, and a mother from Adi Quala, Eritrea. He graduated from the General Wingate high school in Addis Ababa, then studied medicine at Addis Ababa University (at the time known as Haile Selassie University) for two years before interrupting his studies in 1975 to join the TPLF. While a member of the TPLF, he founded the Marxist-Leninist League of Tigray. His first name at birth was "Legesse" (thus Legesse Zenawi, Ge'ez: ለገሰ ዜናዊ legesse zēnāwī) but he is better known by his nom de guerre Meles. He later changed his first name to "Meles" in honor of a University student and a revolutionary radical who was executed by the previous government in 1975.
