1774

The “shot heard round the world”—the opening salvo of the American Revolution, fired at the Battles of Lexington and Concord—got 1775 off with a bang. Before the year was out, the Second Continental Congress had appointed George Washington to command the troops and Benjamin Franklin to run the post office. Meanwhile in France, King Louis XVI was crowned, likely unaware that he’d one day face his own revolution—and the guillotine.

1775

Few years in U.S. history were more momentous than 1776. The Continental Congress signed the Declaration of Independence and named the new country the United States of America. As the Revolutionary War raged, General George Washington crossed the Delaware River in a successful surprise attack on British-funded mercenaries. The British hanged 21-year-old spy Nathan Hale. And the first working combat submarine (a one-man vessel called the “Turtle”) attacked a British ship in New York Harbor by attaching a powder keg to its hull.

While a few battles remained to be fought, the American Revolution essentially ended in 1781 when British General Cornwallis surrendered his troops to American and French forces at Yorktown. The Articles of Confederation—America’s first constitution—took effect, after ratification by the original 13 states. In what would become California, 44 settlers established Los Angeles, while in South America, Spanish forces brutally executed Tupac Amaru II, leader of a rebellion by indigenous people there.

George Washington became the first president of the United States in 1789, the same year the new U.S. Constitution went into effect and Congress drafted the Bill of Rights. In Paris, rioters stormed the Bastille prison, a key moment in the French Revolution. Things were stormy even at sea, as rebellious British sailors set their tyrannical captain William Bligh adrift in a rowboat—the famous mutiny on the Bounty.

In this year, a new armed conflict erupted between England and America—named, simply, the War of 1812. In Europe, French emperor Napoleon invaded Russia, along with the largest army ever assembled, some 600,000 men. In England, a group known as the Luddites attacked textile mills to destroy newfangled industrial machinery, adding a new word to the language for anyone who opposes technological progress. And in a landmark for folklore, German brothers Jacob and Wilhelm Grimm published their first volume of fairy tales.

In 1861, Abraham Lincoln was inaugurated as America’s 16th president. Just weeks later, the newly formed Confederacy attacked Fort Sumter in South Carolina, igniting the American Civil War. To fund the conflict, Congress enacted the country’s first income tax. Elsewhere in the world, multiple states on the Italian Peninsula united to form the Kingdom of Italy, while multiple European powers invaded Mexico to collect unpaid debts. Back in Britain, The Times gave readers the first-ever published weather forecast.

In 1865, the American Civil War came to an end, President Lincoln was assassinated and the 13th amendment was ratified, abolishing slavery in the U.S. The Secret Service came into being, originally created to prevent widespread counterfeiting that plagued the financial system. Elsewhere in the world, rebels in the Dominican Republic forced out Spanish occupiers to restore their country’s independence, and in England, Lewis Carroll published “Alice’s Adventures in Wonderland.”

The Franco-Prussian War ended in 1871, ending in France’s humiliating defeat. What emerged: a new and expanded German Empire, and the revolutionary Paris Commune, which briefly overthrew the French government. In Africa, journalist Henry Stanley began his famous search for missing explorer Dr. Livingstone. In the U.S., fire destroyed much of Chicago, forcing the young city to rebuild from the ground up, the first professional association of baseball players formed and, in Brooklyn, P.T. Barnum debuted his first traveling circus.

After the highly contested 1876 U.S. presidential election, the Compromise of 1877 put Rutherford B. Hayes in the White House. In exchange, post-Civil War federal oversight of Southern affairs known as Reconstruction ended—and, with it, any effort toward protecting Black citizens’ civil and political rights. The first general strike in U.S. history—by more than 100,000 workers—halted the nation’s railroads. Thomas Edison demonstrated his latest invention, the phonograph, while in Moscow, Tchaikovsky’s opera “Swan Lake” premiered in Moscow.

U.S. President James A. Garfield took the oath of office in March, only to die from an assassin’s bullet six months later. Out West, Indian leader Sitting Bull surrendered to the U.S. Army, while lawmen and cattle rustlers had a 30-second gunfight at the O.K. Corral. In Russia, the assassination of Czar Alexander II led to violent attacks—or “pogroms”—on Russian Jews. Black educator Booker T. Washington founded the Tuskegee Institute, and nurse-humanitarian Clara Barton established the American Red Cross.

The nearly 1,000-foot Eiffel Tower opened for business in Paris in 1889, reigning as the tallest structure in the world until 1930. That same year, fire in Seattle destroyed much of the city, while the Johnstown Flood in Pennsylvania swept more than 2,200 to their deaths after a dam collapse. In Japan, the videogame company now known as Nintendo started in business as a maker of playing cards.

In a year that would revolutionize transportation, Henry Ford’s introduced his first Model T and the Wright Brothers’ made their first public flight to demonstrate the airplane they’d invented several years earlier. In Europe, Austria-Hungary annexed Bosnia and Herzegovina, now seen as a prelude to World War I. In America, Sears started selling "kit" homes through its mail-order catalog, starting for $650. And the charismatic outlaws Butch Cassidy and the Sundance Kid reportedly met their end in Bolivia—although not everyone believed it.

The sinking of the Titanic dominated headlines in 1912, a dramatic year on land and sea. The last emperor of China abdicated, while Teddy Roosevelt ran for president on the Bull Moose Party ticket, surviving an assassination attempt before losing to Woodrow Wilson. Native American athlete Jim Thorpe won two gold medals at the Stockholm Olympics, only to be stripped of them for eligibility issues. “Tarzan of the Apes” first appeared in fiction, and the National Biscuit Company introduced the Oreo cookie.

1913

After a Bosnian Serb nationalist assassinated Archduke Franz Ferdinand, Austria-Hungary declared war on Serbia, launching World War I. Other nations began to choose sides in the conflict, but the U.S. remained initially neutral. In Central America, the Panama Canal opened after 11 years of construction and the loss of more than 25,000 workers’ lives. On Christmas Eve 1914, British and German soldiers paused their fighting for unofficial Christmas Truce, sharing carols and even a soccer game.

1914

The horrors of modern warfare were on full view in 1915, the second year of World War I. A German U-boat sank the passenger liner Lusitania off Ireland, German zeppelins bombed London, the French developed a fighter plane that could fire precisely timed machine-gun bullets through its propeller, and German troops unleashed poison gas for the first time on the battlefield. In America, meanwhile, a young Boston Red Sox pitcher named Babe Ruth clubbed his first major-league homer.

1916

Across the globe, 1917 brought upheaval. Russians overthrew Czar Nicholas II, then staged a second revolution, putting Vladimir Lenin’s Bolsheviks in power and sparking a civil war. The U.S. and China both declared war on Germany, entering World War I in its fourth year. Puerto Ricans gained U.S. citizenship. And as America’s first-ever female congresswoman took office, the push for women’s suffrage intensified, with increased picketing and the arrest of many activists, followed by jailhouse hunger strikes, force feedings and mistreatment.

1917

World War I ended in 1918, when Germany signed an armistice agreement with the victorious Allies. The war had cost the lives of more than 9 million combatants plus millions of civilians. Meanwhile, an even more deadly threat emerged: the influenza pandemic, which would take another 50 million lives worldwide. Bolshevik revolutionaries executed the Romanov family, ending 300 years of Russian imperial rule. On the U.S. homefront, Congress enacted daylight savings time, only to repeal it the following year.

1918

1919

The first year of Roaring Twenties in the U.S. brought votes for women and an official start to the nationwide ban on alcohol. The League of Nations met for the first time in Geneva, and the Mexican Revolution ended after 10 years. The Band-Aid debuted, the first commercial radio broadcast hit the airwaves, transmitting the Harding-Cox presidential race results, and Jazz Age author F. Scott Fitzgerald published his first novel, “This Side of Paradise.”

1920

As Europe struggled to recover from WWI, two major figures of the next war ascended. In Germany, Adolph Hitler became leader of the Nazi Party, while Benito Mussolini was elected to Italy’s parliament, soon becoming prime minister and then, dictator. In America, the Tulsa Race Massacre took hundreds of Black lives, an atrocity largely covered up for decades. Meanwhile, Black culture began flourishing in the Harlem Renaissance, and Pittsburgh’s KDKA broadcast the first live sporting event on radio: a boxing match.
