Internment is the imprisonment of people, commonly in large groups, without charges or intent to file charges. The term is especially used for the confinement "of enemy citizens in wartime or of terrorism suspects". Thus, while it can simply mean imprisonment, it tends to refer to preventive confinement rather than confinement after having been convicted of some crime. Use of these terms is subject to debate and political sensitivities. The word internment is also occasionally used to describe a neutral country's practice of detaining belligerent armed forces and equipment on its territory during times of war, under the Hague Convention of 1907.

The Ten Years' War, also known as the Great War and the War of '68, was part of Cuba's fight for independence 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.
