Originally how many states of the US were there during colonial rule?

The premise of your question is incorrect. During colonial rule, which lasted from the early 1600s to the late 1700s, the territory that is now the United States did not consist of states but rather colonies under the rule of various European powers, primarily Great Britain. It was only after the American Revolution and the Declaration of Independence in 1776 that the states began to establish themselves as sovereign entities, leading to the formation of the United States of America.
