Hailing America's "limitless" possibilities now that "a decade of war is ending," President Barack Obama addressed the nation after being publicly sworn in to his second term as president.
Chief Justice John Roberts administered the oath of office in front of a sea of onlookers on the Inaugural Platform and across the National Mall.
Shortly before Obama was sworn in, Supreme Court Justice Sonia Sotomayor administered the oath of office for Vice President Joe Biden.
Echoing the themes of Martin Luther King Day, which the Inauguration coincided with, Obama compelled his fellow Americans to strive for equality and happiness for all citizens in his inaugural address.
"Our journey is not complete until our wives, our mothers and daughters can earn a living equal to their efforts...our journey is not complete until our gay brothers and sisters are treated like anyone else under the law.
"Our journey is not complete until all our children...know that they are cared for and cherished and always safe from harm.
"That is our generation's task, to make...these values, of life and liberty and the pursuit of happiness real for everyone."
Obama spoke of rising above the fierce partisanship that had raged in Congress and the nation as a whole under his first term.
"We cannot mistake absolutism for principle, or substitute spectacle for politics, or treat name-calling as reasoned debate...the oath I have sworn before you today...was an oath to God and country, not party or faction."
Monday was the second time in two days for the president and vice president to take the oath of office; both were officially sworn in Sunday in private ceremonies. For the seventh time in history, January 20, the Constitutionally-mandated date for the president to be sworn in, fell on a Sunday, necessitating a second, public swearing in on Monday in front of the Capitol.
For Obama, who infamously said the oath of office twice in 2009 after Roberts made a verbal flub while administering it, Monday marks his fourth time total to take the oath. This matches the record set by Franklin Roosevelt, though Roosevelt only said it once per inauguration.
Though the crowd stretched across the National Mall appeared endless, it was actually a far cry from the 1.8 million who attended Obama's first swearing in. Political analysts say the drop-off is to be expected, both because a second term is generally not as exciting to the public, and more notably, 2009 was a historical moment with Obama becoming the first minority president.
The crowd, however, was bigger than anticipated.
