The Boston Tea Party was important because it showed the American colonies had grown tired of arbitrary taxation by the British. When the East Indian company was allowed to sell tea directly to America, the British instead the the tax be paid on it. This culminated in the dumping of tea cargoes into Boston Harbor.
Religion helped African Americans become slaves. most Christian preachers made people believe that African Americans were animals without souls. When this idea was spread, rich people began to believe that slaves were property because they were animals. However religion amongst slaves was encouraging to them. They preached among themselves and it gave many the strength to carry on each day. It even encouraged some to run away to the north and to gain their freedom. A very shameful role. People [ some preachers ] promoted the idea that Blacks were animals, therefore no souls, so it left people who should have known better feel free to treat slaves as animals or property
