Barack Obama, First US Black President

America's first black president, Barack Obama, was elected last Tuesday night in a historic triumph that overcame racial barriers as old as America itself.

The son of a black father from Kenya and a white mother from Kansas, the Democratic senator from Illinois sealed his victory by defeating Republican Sen. John McCain in a string of wins in hard-fought battleground states — Ohio, Florida, Virginia and Iowa.

A huge crowd in Grant Park in Chicago erupted in jubilation at the news of Obama's victory. Some wept.

McCain called his former rival to concede defeat — and the end of his own 10-year quest for the White House. "The American people have spoken, and spoken clearly," McCain told disappointed supporters in Arizona.

Obama and his running mate, Sen. Joseph Biden of Delaware, will take their oaths of office as the 44th president of the United States and vice president on Jan. 20, 2009.
