During the colonial era, Americans were bound by British law. Now, they were no longer governed by the Crown or by colonial charter. Independent, Americans could seek to eliminate or maintain laws as they saw fit. The possibilities were endless. Republican revolutionary sentiment brought significant change during the immediate postwar years.
Huge changes were made regarding land holding. English law required land to be passed down in its entirety from father to eldest son. This practice was known as primogeniture. This kept land concentrated in the hands of few individuals, hardly consistent with revolutionary thinking. Within fifteen years of the Revolution, not a single state had a primogeniture law on the books. The cries of the landless, those who formerly paid quitrents and fees to the Crown, could now be heard. Huge estates of the Loyalists were divided into smaller units. These land seizures were harshest in New England, but existed to some extent throughout the American colonies. The sale of the Penn family estate yielded over a million dollars to the new government. In addition, the Treaty of Paris granted the United States land out to the Mississippi River, which created a great opportunity for land hungry citizens to go west. Despite the fact that much of this land was gobbled up by rich land speculators, the removal of the Loyalists served to be a great social leveler.
The fight for separation of church and state was on. In Virginia, it hardly seemed appropriate to support the Anglican Church of England with tax dollars. The Anglican Church itself broke from its English hierarchy and renamed itself the Episcopalian Church. Soon they were appointing their own American clergy. Thomas Jefferson helped win the battle for religious freedom in Virginia. The Congregational Puritan churches in New England held on longer; however, by 1833, all states abandoned the practice of a state-supported church. The Revolution had sparked great changes indeed.
