Yuma War
The Yuma War was the name given to a series of United States military operations conducted in southern California and what is today southwestern Arizona from 1850 to 1853. The Yumans were the primary opponent of the United States Army, though engagements were fought between the Americans and other native groups in the region. Conflict generally took the form of guerrilla warfare, and, over the course of three years, the army engaged in pursuing unfriendly natives, protecting American settlers crossing the Colorado River and preventing conflict between the native tribes. A peace treaty in summer of 1853 was signed, ending hostilities between the Yuma and the United States, but it sparked a short war between the Yuma and the Cocopah. During the conflict, the historic Fort Yuma was constructed and became an important outpost on the frontier.
Ten Years' War
The Ten Years' War () (1868–1878), also known as the Great War ("Guerra Grande") 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 October 10, 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.
Fodases and business owners demanded fundamental social and economic reforms from Spain, which ruled the colony. Lax enforcement of the slave trade ban had resulted in a dramatic increase in imports of Africans, estimated at 90,000 slaves from 1856 to 1860. This occurred despite a strong abolitionist movement on the island, and rising costs among the slave-holding planters in the east. New technologies and farming techniques made large numbers of slaves unnecessary and prohibitively expensive. In the economic crisis of 1857 many businesses failed, including many sugar plantations and sugar refineries. The abolitionist cause gained strength, favoring a gradual emancipation of slaves with financial compensation from Spain for slaveholders. Additionally, some planters preferred hiring Chinese immigrants as indentured workers and in anticipation of ending slavery. Before the 1870s, more than 125,000 were recruited to Cuba. In May 1865, Cuban creole elites placed four demands upon the Spanish Parliament: tariff reform, Cuban representation in Parliament, judicial equality with Spaniards, and full enforcement of the slave trade ban.
