Both dominated the front pages of every newspaper in the country for a good part of the early '70s. American troops left Vietnam in 1973, but the last Americans there were airlifted off the roof of the American Embassy in April 1975 as Saigon fell to the North Vietnamese. The Watergate scandal ended with the resignation of President Richard M. Nixon in August 1974, leaving the nation stunned and cynical about government. But popular music played on everyone's radio, and the young felt liberated from social conventions of previous decades as the youth rebellion of the late 1960s bore fruit. The decade closed with 52 American hostages being held for 444 days in Iran, starting on Nov. 4, 1979, only to be released as Ronald Reagan was inaugurated as president on Jan. 20, 1981. 1:36 Watch Now: A Brief History of the 1970s 1970 Aswan Dam in Egypt.

On May 4, 1970, students at Kent State University in Ohio staged protests that included setting fire to the ROTC building. The Ohio National Guard was called in, and the guardsmen fired on the student protesters, killing four and injuring nine. In sad news for many, The Beatles announced they were breaking up. As a sign of things to come, computer floppy disks made their first appearance. The Aswan High Dam on the Nile, under construction throughout the 1960s, opened in Egypt. 1971 Keystone/Getty Images In 1971, a relatively quiet year, London Bridge was brought to the U.S. and reassembled in Lake Havasu City, Arizona, and VCRs, those magical electronic devices that allowed you to watch movies at home anytime you like or record TV shows, were introduced. 1972 Corbis via Getty Images/Getty Images In 1972, major news was made at the Olympic Games in Munich: Terrorists killed two Israelis and took nine hostages, a firefight ensued, and all nine Israelis were killed along with five of the terrorists. At the same Olympic Games, Mark Spitz won seven gold medals in swimming, a world record at that time. The Watergate scandal began with the break-in at the Democratic National Committee headquarters in the Watergate complex in June 1972. The good news: "M*A*S*H" premiered on television, and pocket calculators became a reality, making struggles with calculation a thing of the past. 1973 Alexander Calder's moving mural in the lobby of the Sears Tower during dedication.

Skylab, America's first space station, was launched; the U.S. pulled its last troops out of Vietnam, and Vice President Spiro Agnew resigned under a cloud of scandal. The Sears Tower was completed in Chicago and became the tallest building in the world; it kept that title for nearly 25 years. Now called the Willis Tower, it is the second-tallest building in the United States. 1974 Bettmann Archive/Getty Images In 1974, heiress Patty Hearst was kidnapped by the Symbionese Liberation Army, who demanded a ransom in the form of a food giveaway by her father, newspaper publisher Randolph Hearst. The ransom was paid, but Hearst was not freed. In tantalizing developments, she ultimately joined her captors and assisted in robberies and professed to have joined the group. She was later captured, tried and convicted. She served 21 months of a seven-year sentence, which was commuted by President Jimmy Carter. She was pardoned by President Bill Clinton in 2001. In August 1974, the Watergate scandal reached its climax with the resignation of President Richard Nixon in the wake of impeachment in the House of Representatives; he resigned to avoid conviction by the Senate. Other events in that year include the deposing of Ethiopian Emperor Halie Selassie, the defection of Mikhail Baryshnikov to the U.S. from Russia, and the killing spree of serial killer Ted Bundy. 1975 Arthur Ashe hitting a backhand shot at Wimbledon.
