1817
First Cholera Pandemic
From the Ganges delta, the vibrio traveled by pilgrim, trader, and soldier across Asia and the Middle East. Bengal villages emptied in days; Astrakhan reported piles of bodies. It was the first time the West met cholera, and the first of seven pandemics that would haunt the century. The disease would reach Britain in 1831, killing tens of thousands and forcing governments to confront the filth of industrial cities.
Shaka Transforms War
The young Zulu king Shaka abandoned traditional throwing spears and long-range posturing in favor of a short stabbing assegai and the "buffalo horns" enveloping formation. His impis trained barefoot to run fifty miles a day. Within a decade he had subjugated most of what is now KwaZulu-Natal and set off the mfecane - the scattering of peoples across southern Africa.
Monroe Inaugurated
James Monroe took the oath outside a still-rebuilding Capitol and began what a Boston newspaper would call the Era of Good Feelings. It was briefer than advertised, but for a moment the Federalists were dead, Jefferson's republicans ruled unopposed, and the young country pretended party politics had ended. The Missouri crisis of 1820 would shatter the illusion and reveal slavery as the fault line through American unity.
Mississippi Statehood
Carved out of the western half of the Mississippi Territory, Mississippi entered the Union as the twentieth state and a cotton-producing engine of the expanding slave economy. Its constitution enshrined slavery and barred free Black residents from entering. The deepening of the cotton South had a political shape, state by new state, through the 1820s.
