Holy Roman Empire Timeline

(800–1806)

The Holy Roman Empire was a complex multi-ethnic political entity in Central Europe that existed from 800, when Charlemagne was crowned Emperor by Pope Leo III, until its dissolution in 1806 under pressure from Napoleon. Though it claimed continuity with the ancient Roman Empire, it was largely a loose confederation of hundreds of kingdoms, duchies, free cities, and ecclesiastical territories centered on Germany, with the Habsburg dynasty dominating its later centuries.
