The century that changed everything — from horse and buggy to the internet.
The 20th century saw more change than any other in human history — global population quadrupled from 1.6 billion to 6 billion, two world wars reshaped borders and alliances, and technology leapt from the Wright Brothers' 12-second flight to the International Space Station. This quiz walks you through every decade, from the 1900s to the 1990s.
Each round presents 10 randomized questions from a pool of 50, with four multiple-choice options and instant feedback after every answer. Your final score comes with a performance tier and shareable results.
You'll explore world-shaping events decade by decade — the sinking of the Titanic, the trenches of WWI, the Roaring Twenties, the Great Depression, D-Day, the Cold War standoff, the Moon landing, Watergate, the fall of the Berlin Wall, and the dawn of the internet age.
The most pivotal events include World War I (1914–1918), World War II (1939–1945), the dropping of the atomic bombs on Hiroshima and Nagasaki in 1945, the Moon landing in 1969, the fall of the Berlin Wall in 1989, and the creation of the World Wide Web in 1991. These events fundamentally reshaped geopolitics, technology, and daily life around the globe.
The 1960s were defined by the Civil Rights Movement, the assassination of President John F. Kennedy in 1963, the escalation of the Vietnam War, the counterculture revolution, and the Apollo 11 Moon landing on July 20, 1969. It was a decade of profound social upheaval and technological achievement.
The 20th century produced transformative inventions including powered flight (1903), the assembly line (1913), penicillin (discovered 1928, mass-produced 1940s), nuclear energy (1942), the transistor (1947), the polio vaccine (1955), the integrated circuit (1958), and the World Wide Web (1991). These breakthroughs revolutionized transportation, medicine, communication, and computing.
