9. Third Cholera Pandemics
Death toll: 1.5 million
Year: 1852–60
In 1852, a new cholera outbreak, that was one of the biggest epidemics in human history, occurred in the Ganges delta. Just like the previous two times, it quickly found its way through Iran and Iraq and into Southern Russia and Europe. The continent was still reeling from the previous epidemics that lasted from 1829 to 1851 when a fresh wave of illness struck. This time it meant business, and the Third Cholera Pandemics is considered to be the deadliest among the seven that laid waste to the world in the 19th and 20th century.
