Answer:
The American Civil War, 1861–1865, resulted from long-standing sectional differences and questions not fully resolved when the United States Constitution was ratified in 1789, primarily the issue of slavery and states rights. With the defeat of the Southern Confederacy and the subsequent passage of the XIII, XIV, and XV amendments to the Constitution, the Civil War’s lasting effects include abolishing the institution of slavery in America and firmly redefining the United States as a single, indivisible nation rather than a loosely bound collection of independent states.
It was a war that saw many “firsts” that included America’s first income tax, the first battle between ironclad ships, the first extensive use of black soldiers and sailors in U.S. service, the first use of quinine to treat typhoid fever, America’s first military draft, and many others. There were advances in medical treatment, military tactics and the chaplain service. Over the course of the Civil War, weapons ranged from obsolete flintlocks to state-of-the-art repeaters. During the war, women took on new roles, including running farms and plantations and working as spies; some disguised themselves as men and fought in battle. All of the nation’s ethnic groups participated in the war, including Irish, Germans, American Indians, Jews, Chinese, Hispanics, etc.
