Overview

Barack Obama, the 44th president of the United States, held office during a transformative period in American history. His presidency marked significant shifts in healthcare policy, foreign relations, and domestic social progress.

As the first African American to occupy the White House, Obama's election was a historic milestone. His administration faced major challenges, including the aftermath of the 2008 financial crisis and ongoing military engagements abroad.

• January 20, 2009: Obama was inaugurated as president following his victory over Senator John McCain in the 2008 election.
• 2010 Affordable Care Act: Also known as Obamacare, this landmark legislation expanded health insurance access to millions of Americans.
• 2011 Osama bin Laden raid: U.S. Navy SEALs killed the al-Qaeda leader during Obama’s first term, marking a pivotal counterterrorism success.
• Re-election in 2012: Obama defeated Republican nominee Mitt Romney with 332 electoral votes to 206.
• January 20, 2017: Obama left office after completing two full terms, succeeded by Donald Trump.

How It Works

The U.S. presidential term structure defines how long a president serves and under what conditions they may continue in office.

• Term: A presidential term lasts exactly four years, beginning and ending on January 20 following the election. Obama served two such terms from 2009 to 2017.
• 22nd Amendment: Limits presidents to two elected terms, which prevented Obama from running again in 2016 despite high approval ratings.
• Election cycle: Presidential elections occur every four years in November, with the winner taking office the following January.
• Transition period: After Election Day, there is a 72-day transition period before the new president is sworn in on Inauguration Day.
• Succession: After Obama’s term ended, Donald Trump was inaugurated as the 45th president on January 20, 2017.
• Post-presidency: Former presidents receive lifetime Secret Service protection and often engage in public advocacy or writing.
