The Cuban Liberation Army, colloquially known as the Mambí Army was an insurgent army which was formed in the last third of the 19th century and fought for independence from Spain and the abolition of slavery. It first saw combat in the Ten Years' War (1868–1878) under the command of Carlos Manuel de Céspedes, Ignacio Agramonte, and Carlos Roloff. The independentists were decentralized and operated within their own regions autonomously of each other, until the Assembly of Guáimaro established the Republic-in-Arms of Cuba and the Liberation Army's command structure. After the Pact of Zanjón, a brief uprising called the Little War saw Major-Generals Calixto García and Antonio Maceo lead the Army of Liberation in another attempt at independence and the abolition of slavery, though unsuccessfully. Finally, during the War of Independence, the Liberation Army was once again organized to fight against the Spanish colonial government. The Liberation Army would reach its highest count of active members in the Spanish-American War, when an imminent Cuban-American victory caused hitherto anti-independence elites to join the Liberation Army. These recruits were nicknamed "Sunflowers" because they "point to where the sun is shining".

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.
