Background

The 13 original states came into existence in July 1776 during the American Revolutionary War, as the successors of the Thirteen Colonies, upon agreeing to the Lee Resolution and signing the United States Declaration of Independence. Prior to these events each state had been a British colony; each then joined the first Union of states between 1777 and 1781, upon ratifying the Articles of Confederation, the first U.S. constitution. Also during this period, the newly independent states developed their own individual state constitutions, among the earliest written constitutions in the world. Although different in detail, these state constitutions shared features that would be important in the American constitutional order: they were republican in form, and separated power among three branches, most had bicameral legislatures, and contained statements of, or a bill of rights. Later, from 1787 to 1790, each of the states also ratified a new federal frame of government in the Constitution of the United States. In relation to the states, the U.S. Constitution elaborated concepts of federalism.
