I like XTimeline because I find it to be a great service that is very accessible to high school students. Using XTimeline students can collaborate, just as they would when making a wiki, to build a multimedia timeline.

TimeGlider offers some nicer layout features compared to XTimeline, but is not quite as intuitive to use as XTimeline.

Time Toast is easy to learn to use. To add events to a timeline simply click on the inconspicuous "add an event" button and a simple event box pops up in which you can enter enter text, place a link, or add a picture. T

that the United States would build an even more destructive atomic weapon: the hydrogen bomb, or "superbomb." Stalin followed suit.

As this anticommunist hysteria spread throughout the 1950s, liberal college professors lost their jobs, people were asked to testify against colleagues and "loyalty oaths" became commonplace.

. The Bay of Pigs invasion in 1961 and the Cuban missile crisis the following year seemed to prove that the real communist threat now lay in the unstable, postcolonial "Third World" Nowhere was this more apparent than in Vietnam, where the collapse of the French colonial regime had led to a struggle between the American-backed nationalist Ngo Dinh Diem in the south and the communist nationalist Ho Chi Minh in the north. Since the 1950s, the United States had been committed to the survival of an anticommunist government in the re

nstead of viewing the world as a hostile, "bi-polar" place, he suggested, why not use diplomacy instead of military action to create more poles? To that end, he encouraged the United Nations to recognize the communist Chinese government and, after a trip there in 1972, began to establish diplomatic relations with Beijing. At the same time, he adopted a policy of "détente"–"relaxation"–toward the Soviet Union. In 1972, he and Soviet premier Leonid Brezhnev (1906-1982) signed the Strategic Arms Limitation Treaty (SALT I), which prohibited the manufacture of nuclear missiles by both sides and took a step toward reducing the decades-old threat of nuclear war.

the Berlin Wall–the most visible symbol of the decades-long Cold War–was finally destroyed, just over two years after Reagan had challenged the Soviet premier in a speech at Brandenburg Gate in Berlin: "Mr. Gorbachev, tear down this wall." By 1991, the Soviet Union itself had fallen apart. The Cold War was over.

In 1959, the Soviet space program took another step forward with the launch of Luna 2, the first space probe to hit the moon

In April 1961, the Soviet cosmonaut Yuri Gagarin became the first person to orbit Earth, traveling in the capsule-like spacecraft Vostok 1. For the U.S. effort to send a man into space, dubbed Project Mercury, NASA engineers designed a smaller, cone-shaped capsule far lighter than Vostok; they tested the craft with chimpanzees, and held a final test flight in March 1961 before the Soviets were able to pull ahead with Gagarin's launch. On May 5, astronaut Alan Shepard became the first American in space (though not in orbit).

Later that May, President John F. Kennedy made the bold, public claim that the U.S. would land a man on the moon before the end of the decade. In February 1962, John Glenn became the first American to orbit Earth, and by the end of that year, the foundations of NASA's lunar landing program--dubbed Project Apollo--were in place.
