True, Robert Smalls was born into slavery in South Carolina and was hired out to work on steamboats as a youth. He was born an African-American slave, and during and after the Civil War became a ship's pilot, sea captain, as well as a politician. He freed himself, his family and other slaves and convinced Lincoln to let African-American soldiers fight during the war.
The main thing thatPresident Lincoln risked if he chose not to resupply Fort Sumter was looking weak and ineffectual in the face of the South.

The bubonic plaque changed the social structure of Europe by this:
Before, the nobles and aristocrats were the 'body' that ran almost everything political. However, after the bubonic plague, this was shifted towards the common people. So the common people basically got more rights.
hope this helps :D
