Answer:
The correct answer is D. The Confederate States of America was created from states that had seceded from the Union.
Step-by-step explanation:
Confederate States of America was an unrecognized confederation of seceded states of the United States of America, which existed from 1861 until 1865. The Confederacy was originally formed by seven slave states in the southern region of the United States of America. Their regional economy was characterized by agriculture, mainly cotton production and where the plantation system depended on slave labor.
Each state had declared its separation from the American Union following the November 1860 election with Republican candidate Abraham Lincoln as president. Lincoln's political platform was to oppose the extension of slavery to other states and territories. A Confederate government was proclaimed in February 1861 before Lincoln formally took office in March, but that government was declared illegal by the US government. After the war broke out in April, a further four states in the northern states declared that they also broke with the union and entered the Confederacy. Missouri and Kentucky were also later accepted as members of the Confederacy, but none of them had officially declared that they broke with the Union or were ever controlled by the Confederate army.
The US government rejected the demands to break out of the Union and regarded the Confederate government as invalid. The Civil War began on April 12, 1861, with the Confederate attack on Fort Sumter, a fortress in the Port of Charleston, South Carolina. In 1865, after very hard warfare, mainly in the Confederate territories, the Confederate's military forces surrendered and the Confederation disbanded.
