The Ten Years' War begins against Spanish rule in Cuba.

The Ten Years' War, also known as the Great War and the War of '68, was a war of independence of Cuba from Spain. The uprising was led by Cuban-born planters and other wealthy natives. On 10 October 1868, sugar mill owner Carlos Manuel de Céspedes and his followers proclaimed independence, beginning the conflict. This was the first of three liberation wars that Cuba fought against Spain, the other two being the Little War (1879–1880) and the Cuban War of Independence (1895–1898). The final three months of the last conflict escalated with United States involvement, leading to the Spanish–American War.
