How and when was the US state formed?

It will be right to start with when this territory was opened. It was discovered by the great traveler Christopher Columbus in 1492. This territory began to be used as a colony (a lot of colonies belonged to modern England). The first thirteen states were formed precisely from the British colonies, then the United States in the eighteenth century began an active struggle for independence, and indeed, in 1776, they managed to become an independent state. (but it took a long time to confirm it).
