"Bacon's Rebellion" was mainly caused by economic hardship and distrust of Virginia colonists who were unable to acquire land.

Explanation:

Bacon's Rebellion was a revolt unleashed in 1676 in the British colony of Virginia by whites living on the border with Native Americans, later joined by black slaves and white servants.

It unleashed about the American Indian threat in a context of agricultural crisis and misery. Border Whites believe that Jamestown's governor, William Berkeley, must wage a total war against the Natives, who had embarked on guerrilla warfare as a result of disputes with the settlers. Nathaniel Bacon, elected to Virginia's House of Commons in the spring, and cousin of Frances Culpeper, the wife of Governor William Berkeley, advocated the establishment of armed detachments to fight the Amerindians. The governor accused him of rebellion and had him imprisoned. Two thousand Virginia settlers immediately marched on Jamestown to lend their support.

Berkeley released Bacon after a promise of public repentance. But Bacon escaped, reforming his militias and started harassing the Natives. In July, he wrote a "Declaration of the People" which reproached the administration for its unjust taxes, its favoritism, its stranglehold on the fur trade and its abandonment of the farmers facing the Amerindians. Bacon then attacked the Amerindian pamunkeys, considered harmless, killing eight, making prisoners and seizing their property. In the fall, he fell ill and died at the age of 26. A thirty-gun ship, commanded by Thomas Grantham, was tasked by the British crown with subduing the revolt. Twenty-three rebel leaders were hanged. The Virginia assembly would amnesty most whites who participated in the revolt, but not blacks.

by 1890, the united states had by far the world's most productive economy. american industry produced twice as much as its closest competitor--britain. but the united states was not a great military or diplomatic power. its army numbered less than 30,000 troops, and its navy had only about 10,000 seamen. britain's army was five times the size of its american counterpart, and its navy was ten times bigger. the united states' military was small because the country was situated between two large oceans and was surrounded by weak or friendly nations. it faced no serious military threats and had little interest in asserting military power overseas.
