On November 6, 1860 Abraham Lincoln was elected President of the United States -- an event that outraged southern states. The Republican party had run on an anti-slavery platform, and many southerners felt that there was no longer a place for them in the Union. On December 20, 1860, South Carolina seceded. By Febrary 1, 1861, six more states -- Mississippi, Florida, Alabama, Georgia, Louisiana, and Texas -- had split from the Union. The seceded states created the Confederate States of America and elected Jefferson Davis, a Mississippi Senator, as their provisional president.

In his inaugural address, delivered on March 4, 1861, Lincoln proclaimed that it was his duty to maintain the Union. He also declared that he had no intention of ending slavery where it existed, or of repealing the Fugitive Slave Law -- a position that horrified African Americans and their white allies. Lincoln's statement, however, did not satisfy the Confederacy, and on April 12 they attacked Fort Sumter, a federal stronghold in Charleston, South Carolina. Federal troops returned the fire. The Civil War had begun. .

i do not know if this question has options, but a main impact of the federal reserve act of 1913, which created the federal reserve bank, was the international use of the u.s. dollar, which soon became the world's leading currency - particularly during world war i, since many nations around the world asked the united states for money.
