The American Revolution
The American Revolution (1775-83) is also known as the American Revolutionary War and the U.S. War of Independence. The conflict arose from growing tensions between residents of Great Britain's 13 North American colonies and the colonial government, which represented the British crown. Skirmishes between British troops and colonial militiamen in Lexington and Concord in April 1775 kicked off the armed conflict, and by the following summer, the rebels were waging a full-scale war for their indepe -
Lewis and Clark
In 1804, Jefferson sends a team to explore lands acquired in the Louisiana Purchase. The Corps of Discovery will travel nearly 8,000 miles over three years, reaching the Pacific Ocean and clearing the path for westward expansion. -
Civil War
In the spring of 1861, decades of simmering tensions between the northern and southern United States over issues including states' rights versus federal authority, westward expansion and slavery exploded into the American Civil War (1861-65). The election of the anti-slavery Republican Abraham Lincoln as president in 1860 caused seven southern states to secede from the Union to form the Confederate States of America; four more joined them after the first shots of the Civil War were fired. Four y -
Stopping Slavery
On this day in 1865, the 13th Amendment to the U.S. Constitution, officially ending the institution of slavery, is ratified. "Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction." With these words, the single greatest change wrought by the Civil War was officially noted in the Constitution. -
The Great Depression
The Great Depression (1929-39) was the deepest and longest-lasting economic downturn in the history of the Western industrialized world. In the United States, the Great Depression began soon after the stock market crash of October 1929, which sent Wall Street into a panic and wiped out millions of investors. Over the next several years, consumer spending and investment dropped, causing steep declines in industrial output and rising levels of unemployment as failing companies laid off workers. By -
Pearl Harbor
Just before 8 on the morning of December 7, 1941, hundreds of Japanese fighter planes attacked the American naval base at Pearl Harbor near Honolulu, Hawaii. The barrage lasted just two hours, but it was devastating: The Japanese managed to destroy nearly 20 American naval vessels, including eight enormous battleships, and almost 200 airplanes. More than 2,000 Americans soldiers and sailors died in the attack, and another 1,000 were wounded. The day after the assault, President Franklin D. Roose -
Vietnam
The Vietnam War was a long, costly armed conflict that pitted the communist regime of North Vietnam and its southern allies, known as the Viet Cong, against South Vietnam and its principal ally, the United States. The war began in 1954 (though conflict in the region stretched back to the mid-1940s), after the rise to power of Ho Chi Minh and his communist Viet Minh party in North Vietnam, and continued against the backdrop of an intense Cold War between two global superpowers: the United States -
The Moon Landing
On July 20, 1969, American astronauts Neil Armstrong (1930-) and Edwin “Buzz” Aldrin (1930-) became the first humans ever to land on the moon. About six-and-a-half hours later, Armstrong became the first person to walk on the moon. As he set took his first step, Armstrong famously said, "That's one small step for man, one giant leap for mankind." The Apollo 11 mission occurred eight years after President John Kennedy (1917-63) announced a national goal of landing a man on the moon by the end of -
Internet
Unlike technologies such as the light bulb or the telephone, the Internet has no single “inventor.” Instead, it has evolved over time. The Internet got its start in the United States more than 50 years ago as a government weapon in the Cold War. For years, scientists and researchers used it to communicate and share data with one another. Today, we use the Internet for almost everything, and for many people it would be impossible to imagine life without it. -
9-11
Shortly after the Twin Towers fell on September 11, 2001, the nation began to mourn, and around the country Americans began to commemorate the victims and demonstrate their patriotism. Some flew the American flag from their front porches and car antennas. Others pinned it to their lapels or wore it on t-shirts. Sports teams postponed games. Celebrities organized benefit concerts and performances. People attended impromptu candlelight vigils and participated in moments of silence. They gathered i
