Barack Obama, born August 4, 1961 in Honolulu, Hawaii, is a Leo who served as the 44th president of the United States from 2009 to 2017. He made history as the first African American president, winning the 2009 Nobel Peace Prize during his first term. Before his presidency, Obama represented Illinois in the U.S. Senate from 2005 to 2008 and worked as a civil rights attorney and constitutional law professor at the University of Chicago.

Obama was born to an 18-year-old American mother from Kansas and a 27-year-old Kenyan father who met in a Russian language class at the University of Hawaii. He graduated from Columbia University in 1983 with a degree in political science, then worked as a community organizer in Chicago before enrolling at Harvard Law School in 1988, where he became the first black president of the Harvard Law Review. From 1997 to 2004, Obama served in the Illinois State Senate representing the 13th district, teaching constitutional law at the University of Chicago Law School throughout that period.

Obama married Michelle Obama in 1992, and together they have two daughters, Malia and Sasha. His parents divorced in 1964 when he was three, and his father returned to Kenya, where he died in a car accident in 1982. Obama's mother remarried an Indonesian student, and the family moved to Jakarta in 1967, where Obama lived until age ten before returning to Honolulu to live with his maternal grandparents. After leaving office in 2017, Obama continued to reside in Washington, D.C., remaining politically active and publishing three bestselling books including his 2020 memoir A Promised Land.
