It is all about the history! The Anglican Church was created so that Henry VIII could get divorced from his first wife and marry Anne Boleyn. Though theologians such as Martin Luther had been pressing for reform on behalf of the protestants prior to this.
Key differences: Episcopalian's do not believe in the papacy... that role was taken on by the King of England. Here in American, there in less order and groups have broken even further in their ideals of what they do or do not believe. Episcopalian's do not believe that Christ is present during the Eucharist. They do not believe the bread and wine become body and blood.
Oddly, the Catholic Church has remained the same for a long, long time- and it lost many members... though currently it has begun a steady increase in membership while the Episcopalian church has broken apart in it's beliefs and has steadily been losing members!
