Ripples of History is an interactive atlas of cause and effect in world history, 1800 to the present. More than 550 events — revolutions, inventions, wars, crises and ideas — are plotted on a world map and joined by over 1,500 causal links, each with a short written justification. Tap any event to see what caused it and what it set in motion, follow a causal thread across two centuries, or watch the whole period ripple across the map in thirty seconds.
Guided journeys tell connected stories step by step: the Cold War from Marx to the war in Ukraine, the digital age from Ada Lovelace to generative AI, the world wars from Sarajevo to the Universal Declaration of Human Rights, two centuries of boom and bust from steam to Bitcoin, the end of empires, the fight for the vote, the war on disease, and more. Twelve region stories cover every part of the world, and the Six Degrees game challenges you to connect any two events through real causal links.
