History explained, step by step
History is easiest to remember when it's a story with causes and consequences, not a list of dates. Why did the French Revolution happen when it did? How did a single assassination drag the world into the First World War? What did Indian independence and partition actually change for ordinary people? Know.it's history lessons answer questions like these with animated timelines and maps, so you can see events unfold in order and understand why one thing led to the next.
This page collects our free history explainers: ancient civilisations like Egypt, Greece and Rome; medieval empires including the Mughals, Mongols and Ottomans; the revolutions and wars that shaped the modern world; and ideas such as colonialism, feudalism and propaganda. Each catalog card opens a short written explanation with key points. Visual lessons can be requested using available credits or plan allowance.
