The significant revolutions that took place during this time period are the focus of Period 3 of the AP World History course, which covers the years roughly between 1750 and 1900. During this time, old cultures and empires fell into disrepair along with the rise of the nationalism and industrialization movements. The American Revolution (1775–1783), the French Revolution (1789–1799), the Haitian Revolution (1791–1804), and the Taiping Rebellion are just a few of the significant revolutions that occurred during this time (1850-1864). The modern nation-state also came into being during this time, and the world economy expanded.
