The United States fought five wars in the 1900s:
The main concern of the United States during the Cold War was the spread of communism. The Soviet Union (Union of Soviet Socialist Republics, or USSR) was a powerful nation that operated under the principles of communism. The United States and its allies believed that a democratic government and a capitalist economy were the best ways to preserve individual rights and freedoms. The United States and its allies feared the expansion of communism to countries outside the Soviet Union. The Cold War began shortly after the end of World War II and lasted for more than 40 years. It ended with the fall of the Berlin Wall in 1989, the reunification of East and West Germany in 1990, and the breakup of the USSR in 1991.
Civil Rights Movement
The modern civil rights movement in the United States began in 1954 when the Supreme Court ruled that racial segregation in public schools was unconstitutional. The goal of the civil rights movement was to end racial discrimination against African Americans and to gain full and equal rights for Americans of all races. Using nonviolent strategies such as bus boycotts, sit-ins, and marches, people came together to demand social change. As a result, Congress passed the Civil Rights Act of 1964 and the Voting Rights Act of 1965. The Civil Rights Act made segregation in public facilities and racial discrimination in employment and education illegal. The law protects African Americans, women, and others from discrimination. The Voting Rights Act banned literacy tests and other special requirements that had been used to stop African Americans from registering to vote. A key leader during this movement was Martin Luther King, Jr. . He is famous for his "I Have a Dream" speech, which imagines an American in which people of all races exist together equally. Unfortunately the Nobel Peace Prize winner was killed in 1968, at the young age of thirty-nine (39). He will always be remembered as someone who fought for civil rights ad worked for equality for all Americans.
On September 11, 2001, four airplanes flying out of U.S. airports were taken over by terrorists from the Al-Qaeda network of Islamic extremists. Two of the planes crashed into the World Trade Center's Twin Towers in New York City, destroying both buildings. One of the planes crashed into the Pentagon in Arlington, Virginia. The fourth plane, originally aimed at Washington, D.C., crashed in a field in Pennsylvania. Almost 3,000 people died in these attacks, most of them civilians. This was the worst attack on American soil in the history of the nation.
American Indians lived in North America for thousands of years before the European settlers arrived. Today there are more than 500 federally recognized tribes in the United States. Each tribe has its own social and political system. American Indian cultures are different from one tribe to another, with different languages, beliefs, stories, music, and foods. Earlier in their history, some tribes settled in villages and farmed the land for food. Other tribes moved frequently as they hunted and gathered food and resources. The federal government signed treaties with American Indian tribes to move the tribes to reservations. These reservations are recognized as domestic, dependent nations.
