Barack Hussein Obama II (pronounced /b?'r??k hu?'se?n o?'b??m?/; born
August 4, 1961) is the 44th and current President of the United States and the
first African American to hold the office. Obama was the junior United States
Senator from Illinois from January 2005 until November 2008, when he resigned
following his election to the presidency.
Obama is a graduate of Columbia
University and Harvard Law School, where he was the first African American
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 also taught constitutional law at the University of Chicago Law School from
1992 to 2004.
Obama served three terms in the Illinois Senate from 1997
to 2004. Following an unsuccessful bid for a seat in the U.S. House of
Representatives in 2000, Obama ran for United States Senate in 2004. His victory
from a crowded field in the March 2004 Democratic primary raised his visibility,
and his prime-time televised keynote address at the Democratic National
Convention in July 2004 made him a rising star nationally in the Democratic
Party. He was elected to the U.S. Senate in November 2004 by the largest margin
in Illinois history.
He began his run for the presidency in February
2007. After a close campaign in the 2008 Democratic Party presidential primaries
against Hillary Rodham Clinton, he won his party's nomination, becoming the
first major party African American candidate for president. In the 2008 general
election, he defeated Republican candidate John McCain and was inaugurated as
president on January 20, 2009.
