1.It failed because every colony had their own agenda. New York largely spoke Dutch. New England was largely still puritan. 2.The southern colonies were mostly big plantations, either tobacco, rice, or cotton, and they were run differently than the northern system of small farms and early industry. Pennsylvania was largely Quaker. Maryland accepted Catholics. 3.New England Puritans hated Quakers, Catholics, and Anglicans. Catholics hated all protestants. Anglicans (who were the majority in the south) hated Catholics, Puritans, and Quakers. Quakers didn't get along with anyone. Between religious and economic differences and the unwillingness of one colony to dispense money and troops to help another colony, eg. Georgia, a debtor's prison and the farthest south, wasn't going to take its eyes off of Spanish Florida just to help a bunch of Dutch-speakers in New York, the entire plan fell apart.
