CENTURY

The 19th century lasted from 1801 through 1900 in the Gregorian calendar. Historians sometimes define a "Nineteenth Century" historical era stretching from 1815 (The Congress of Vienna) to 1914 (The outbreak of the First World War); alternatively, Eric Hobsbawm defined the "Long Nineteenth Century" as spanning the years 1789 to 1914. During this century, the Spanish, Portuguese, and Ottoman empires began to crumble and the Holy Roman and Mughal empires ceased. Following the Napoleonic Wars, the British Empire became the world's leading power, controlling one quarter of the World's population and one third of the land area. It enforced a Pax Britannica, encouraged trade, and battled rampant piracy. Slavery was greatly reduced around the world. Following a successful slave revolt in Haiti, Britain forced the Barbary pirates to halt their practice of kidnapping and enslaving Europeans, banned slavery throughout its domain, and charged its navy with ending the global slave trade. Slavery was then abolished in Russia, America, and Brazil (see Abolitionism). Electricity, steel, and petroleum fueled a Second Industrial Revolution which enabled Germany, Japan, and the United States to become Great Powers that raced to create empires of their own. However, Russia and Qing Dynasty China failed to keep pace with the other world powers which led to massive social unrest in both empires.
