The 21st century dawned on a very different presidency than the one created at the end of the 1700s. Constitutional provisions limited the early presidency, although the personalities of the first three — George Washington, John Adams, and Thomas Jefferson — shaped it into a more influential position by the early 1800s. However, throughout the 1800s until the 1930s, Congress was the dominant branch of the national government. Then, in the past seventy years or so, the balance of power has shifted dramatically, so that the executive branch currently has at least equal power to the legislative branch.
