It was a day many Americans will remember for the rest of their lives.
On Jan. 20, an estimated 1.8 million people packed the National Mall in Washington to watch as the country's first African-American president was sworn into office.
"On this day, we gather because we have chosen hope over fear," said President Barack Obama in an inaugural address that took the theme of a "new birth of freedom."
He also spoke of America's cultural and color lines, and of the strength in our diversity:
"We are shaped by every language and culture, drawn from every end of this Earth; and because we have tasted the bitter swill of civil war and segregation, and emerged from that dark chapter stronger and more united, we cannot help but believe ... that the lines of tribe shall soon dissolve; that as the world grows smaller, our common humanity shall reveal itself."
