Declaration of Independence
From the Boston Tea Party to the shot heard round the world, Washington’s Crossing of the Delaware, and the Valley Forge winter, the American Revolution’s pursuit of liberty was made meaningful by the founding document of the great American experiment in democracy. -
Period: to
Constitution of the United States of America
With the war won, independence secured, and the Articles of Confederation proving inadequate, the Founding Fathers laid down the law by which the new country would be governed in the elegantly crafted Constitution, which, depending upon one’s perspective, was meant to either evolve to meet changing circumstances or to be strictly interpreted to adhere to the Founders’ “original intent.” -
Whiskey Rebellion
As the new country began finding its feet, U.S. Pres. George Washington sent troops to western Pennsylvania in 1794 to quell the Whiskey Rebellion, an uprising by citizens who refused to pay a liquor tax that had been imposed by Secretary of Treasury Alexander Hamilton to raise money for the national debt and to assert the power of the national government. -
Louisiana Purchase
The Louisiana Territory, the huge swath of land (more than 800,000 square miles) that made up the western Mississippi basin. Thomas Jefferson pried it away from Napoleon in 1803 for a final price of some $27 million. Out of it were carved—in their entirety—the states of Louisiana, Missouri, Arkansas, Iowa, North Dakota, South Dakota, Nebraska, and Oklahoma along with most of Kansas, Colorado, Wyoming, Montana, and Minnesota. -
Period: to
Monroe Doctrine
The Era of Good Feelings (roughly 1815–25), a period of American prosperity and isolationism, was in full swing when U.S. Pres. James Monroe articulated a set of principles in 1823 that decades later would be called the Monroe Doctrine. -
Battle of New Orleans
On January 8, 1815, a ragtag army under the command of Andrew Jackson decisively defeated British forces in the Battle of New Orleans, even though the War of 1812 had actually already ended. The American victory made a national figure of future president Jackson and contributed to the widespread perception that the U.S. had won the war, but in truth the conflict was effectively a draw, and the issues that had brought it on were largely unresolved. -
Period: to
Era of the Common Man
Andrew Jackson, the U.S. president from 1829–37, was said to have ushered in the Era of the Common Man. Despite the careful propagation of his image as a champion of popular democracy and as a man of the people, he was much more likely to align himself with the influential not with the have-nots, with the creditor not with the debtor. Jacksonian democracy talked a good game for people on the street but delivered little. -
Treaty of Guadalupe Hidalgo
Signed on February 2, 1848, the Treaty of Guadalupe Hidalgo brought to a close the Mexican-American War (1846–48) and seemingly fulfilled the Manifest Destiny of the United States championed by Pres. James K. Polk by adding 525,000 square miles (1,360,000 square km) of formerly Mexican land to the U.S. territory. -
Dred Scott Decision
The 1850s were awash in harbingers of the American Civil War to come—from the Compromise of 1850, which temporarily forestalled North-South tensions, to John Brown’s Harpers Ferry Raid, which ramped them up. Arguably, though, by stoking abolitionist indignation in an increasingly polarized country, the U.S. Supreme Court’s Dred Scott decision set the table for the 1860 election of Abraham Lincoln as president, which ultimately precipitated secession and war. -
Battle of Gettysburg
In July 1863, the year of the Emancipation Proclamation, in the small Pennsylvania crossroads town of Gettysburg, Robert E. Lee’s invading Army of Northern Virginia sustained a defeat so devastating that it sealed the fate of the Confederacy and its “peculiar institution.” Within two years the war was over, and before the end of the decade the South was temporarily transformed by Reconstruction. -
Haymarket Riot
The wealth-concentrating practices of the “robber barons” who oversaw the burst of industrial activity and corporate growth during the Gilded Age of the late 19th century was countered by the rise of organized labor led by the Knights of Labor. However, when a protest meeting related to one of the nearly 1,600 strikes conducted during 1886 was disrupted by the explosion of a bomb that killed seven policeman at the Haymarket Riot. -
Plessy v. Ferguson
With the end of Reconstruction in the 1870s, the enactment of Jim Crow laws enforced racial segregation in the South. In its 7–1 decision in the Plessy v. Ferguson case in May 1896, the U.S. Supreme Court gave constitutional sanction to laws designed to achieve racial segregation by means of separate and supposedly equal public facilities and services for African Americans and whites, thus providing a controlling judicial precedent that would endure until the 1950s. -
Period: to
Breakup of Northern Securities
Theodore Roosevelt pursued the Progressive goal of curbing the enormous economic and political power of the giant corporate trusts by resurrecting the nearly defunct Sherman Antitrust Act to bring a lawsuit that led to the breakup of a huge railroad conglomerate, the Northern Securities Company (ordered by the U.S. Supreme Court in 1904). Roosevelt pursued this policy of “trust-busting” by initiating suits against 43 other major corporations during the next seven years. -
Sinking of the Lusitania
As World War I raged in Europe, most Americans, including U.S. Pres. Woodrow Wilson, remained determined to avoid involvement and committed to neutrality, though the U.S. economy had benefited greatly from supplying food, raw material, and guns and ammunition to the Allies. More than any other single event, the sinking of the unarmed British ocean liner, the Lusitania, by a German submarine on May 7, 1915 (killing, among others, 128 Americans), prompted the U.S. -
Stock Market Crash
“The chief business of the American people is business,” U.S. Pres. Calvin Coolidge said in 1925. And with the American economy humming during the “Roaring Twenties” (the Jazz Age), peace and prosperity reigned in the United States…until it didn’t. The era came to a close in October 1929 when the stock market crashed, setting the stage for years of economic deprivation and calamity during the Great Depression. -
Assassination of Martin Luther King, Jr.
At the center of the widespread social and political upheaval of the 1960s were the civil rights movement, opposition to the Vietnam War, the emergence of youth-oriented counterculture, and the establishment and reactionary elements that pushed back against change. The April 4, 1968, assassination of Martin Luther King, Jr., the most prominent civil rights leader, revealed the tragic, violent consequences that could result from a country’s political polarization. -
Period: to
Watergate Scandal.
On August 9, 1974—facing likely impeachment for his role in covering up the scandal surrounding the break-in at the Democratic National Committee (DNC) headquarters in the Watergate complex in Washington, D.C., in June 1972—Republican Richard Nixon became the only U.S. president to resign. The loss of faith in government officials that resulted from the scandal suffused both popular and political culture with paranoia and disillusionment for the remainder of the decade. -
PATCO Strike
U.S. Pres. Ronald Reagan’s triumph over the strike by the Professional Air Traffic Controllers Organization (PATCO) in August 1981 played a pivotal role in the long-term weakening of the power of labor unions and helped set the tenor for his administration. Reagan’s ascent to the presidency in 1980 had much to do with his rhetorical ability to break the cloud of gloom caused by Watergate. -
The Monica Lewinsky Affair.
Democrat Bill Clinton pivoted toward political accommodation, oversaw a robust economy, and reversed the spiraling budget deficit. Nonetheless, his affair with a White House intern, Monica Lewinsky, led to his impeachment in December 1998, though he was acquitted of charges of perjury and obstruction of justice. -
September 11 Attacks.
Although terrorist attacks had been directed at the United States at the end of the 20th century, a new sense of vulnerability was introduced into American life on September 11, 2001, when Islamist terrorists crashed hijacked planes into the World Trade Center in New York City, the Pentagon in Washington, D.C., and the Pennsylvania countryside, resulting in the deaths of nearly 3,000 people.
