1850s
The 1850s was a decade of the Gregorian calendar that began on January 1, 1850, and ended on December 31, 1859.
It was a very turbulent decade, as wars such as the Crimean War, shifted and shook European politics, as well as the expansion of colonization towards the Far East, which also sparked conflicts like the Second Opium War. In the meantime, the United States saw its peak on mass migration to the American West, that particularly made the nation experience an economic boom, as well as a rapidly increasing population.
The last living person from this decade was Ada Roe, who died in 1970.
