The Battle of Fort Sumter, which took place on April 12-13, 1861, marked the beginning of the Civil War. Confederate forces attacked the Union-held Fort Sumter in South Carolina, and the Union responded by sending troops to relieve the fort. The Confederate attack was successful, and the Union troops were forced to surrender.

Abraham Lincoln served as the president of the United States during the Civil War, from 1861 until his assassination in 1865. He led the Union through the war and issued the Emancipation Proclamation, which freed slaves in Confederate territory.

The main cause of the Civil War was slavery. The Southern states wanted to maintain the institution of slavery, while the Northern states were opposed to it. The issue of slavery had been a source of tension between the North and South for many years, and it eventually led to the outbreak of war.

The Union won the Civil War. The Confederate forces surrendered to the Union army at Appomattox Court House on April 9, 1865, effectively ending the war.

The outcome of the Civil War was the abolition of slavery, the reunification of the United States, and the end of the Confederacy.

The Emancipation Proclamation was a document issued by President Abraham Lincoln on January 1, 1863, that freed slaves in Confederate territory. It did not free slaves in the border states or the District of Columbia, which were still under Union control.

The 13th Amendment to the United States Constitution, ratified in 1865, abolished slavery in the United States. It was the first of the three Reconstruction Amendments, which were passed after the Civil War to ensure the rights of African Americans.

The 14th Amendment to the United States Constitution, ratified in 1868, granted citizenship to African Americans and prohibited states from depriving citizens of life, liberty, or property without due process of law.

The 15th Amendment to the United States Constitution, ratified in 1870, prohibited states from depriving citizens of the right to vote based on race, color, or previous condition of servitude.

The Reconstruction Era was the period after the Civil War when the United States was reunited, the Southern states were under military occupation, and the 13th, 14th, and 15th Amendments were passed.

The Ku Klux Klan was a white supremacist terrorist organization that was active in the Southern United States during the Reconstruction Era. The Klan used violence and intimidation to suppress African Americans and prevent them from exercising their rights.

The Compromise of 1877 was an agreement between the Republican and Democratic parties that ended the Reconstruction Era. The agreement gave the Southern states control over their own affairs and guaranteed the rights of African Americans.

The legacy of the Civil War includes the abolition of slavery, the reunification of the United States, the end of the Confederacy, and the establishment of civil rights for African Americans.

Ulysses S. Grant led the Union army to victory in the Civil War. He was appointed commander of all Union armies in 1864 and led the Union to victory at the Battle of Appomattox Court House, which effectively ended the war.

Robert E. Lee led the Confederate army during the Civil War. He was one of the most successful generals in American history, and his army won many important battles, including the Battle of Chancellorsville and the Battle of Gettysburg.
