History
Americans watched political upheaval abroad and sharp conflict at home throughout 2011. Protests across North Africa and the Middle East removed longtime rulers in Tunisia, Egypt and Libya, while US forces joined a NATO operation over Libya. On May 2 in Pakistan, Navy SEALs killed al-Qaeda leader Osama bin Laden, nearly a decade after the September 11 attacks. Washington spent the summer arguing over the federal debt ceiling, reaching an agreement only days before the Treasury's projected deadline.
Natural and technological disasters arrived in quick succession. A March earthquake and tsunami in Japan caused the Fukushima nuclear accident and disrupted global supply chains. In the United States, a massive tornado destroyed much of Joplin, Missouri, on May 22 and killed 161 people, making it the country's deadliest single tornado since modern records began. Floods, drought and a record number of costly weather disasters made the year's extreme conditions difficult to treat as isolated episodes.
The year also closed chapters in technology and exploration. Space shuttle Atlantis landed on July 21 after the program's 135th mission, ending three decades of shuttle flights. Apple co-founder Steve Jobs died in October after years of illness, one day after the company introduced the iPhone 4S. Occupy Wall Street established a protest camp in September and spread a language of “the 99 percent,” while the last US troops left Iraq in December, formally ending the military mission begun in 2003.
A gunman opened fire at Representative Gabrielle Giffords's constituent meeting outside a Tucson supermarket. Six people were killed and thirteen injured, including Giffords, who survived a gunshot wound to the head and began a long rehabilitation.

Hosni Mubarak resigned after nearly 30 years in power following eighteen days of mass demonstrations centered on Cairo's Tahrir Square. Egypt's military assumed authority as the Arab Spring's most closely watched uprising entered an uncertain transition.
A magnitude 9.0 earthquake off Japan generated a tsunami that destroyed coastal communities and triggered meltdowns at the Fukushima Daiichi nuclear plant. Nearly 20,000 people died or remained missing, and the disaster displaced large populations.
Navy SEALs raided a compound in Abbottabad, Pakistan, and killed al-Qaeda leader Osama bin Laden. President Obama announced the operation late on May 1 in Washington; the raid occurred after midnight on May 2 local time.
Read the full storyA powerful tornado cut across Joplin, killing 161 people and destroying thousands of buildings, including St. John's Regional Medical Center. The storm became the deadliest single US tornado since official records began in 1950.
Read the full storySpace shuttle Atlantis lifted off on STS-135 with four astronauts and supplies for the International Space Station. It landed July 21, ending NASA's 30-year shuttle program after 135 missions and leaving US crews dependent on Russian Soyuz spacecraft.
Read the full storyPresident Obama signed legislation raising the federal debt limit and setting caps on discretionary spending. The prolonged fight unsettled financial markets, and Standard & Poor's lowered the United States' long-term credit rating three days later.
Protesters gathered in lower Manhattan and established a camp in Zuccotti Park, criticizing economic inequality and concentrated financial power. The phrase “We are the 99 percent” spread as related demonstrations formed in cities across the country.
Steve Jobs died after years of illness, one day after Apple introduced the iPhone 4S. The co-founder had returned to Apple in 1997 and overseen products including the iMac, iPod, iPhone and iPad.

The final US military convoy crossed from Iraq into Kuwait, ending the American military mission nearly nine years after the 2003 invasion. A diplomatic and training presence remained, and US forces returned in 2014 to fight the Islamic State group.
