What were the US states divided into other states?

Answer 1

There have been 5 states created from lands once part of other states:

• Vermont declared independence from New York and New Hampshire and was a separate republic from 1777 to 1791.
• Tennessee was originally part of North Carolina, until ceded to the federal government as the Southwest Territory in 1790.
• Kentucky was part of Virginia until it separated to become a state in 1792.
• Maine voted to separate from Massachusetts in 1820, becoming the 23rd US state.
• West Virginia was created in 1863 from the western counties of Virginia that supported the Union in the US Civil War.

Answer 2

Yes. Although under the US Constitution, that would require the consent of the state legislature. Many states were all or partly in territories prior to statehood, and at least 5 were part of another state.

Vermont declared independence from New York and New Hampshire and was a separate republic from 1777 to 1791.

Maine voted to separate from Massachusetts in 1820, becoming the 23rd US state.

West Virginia was created in 1863 from the western counties of Virginia that supported the Union in the US Civil War.

Most of Kentucky was part of Virginia until it separated to become a state in 1792.

Most of Tennessee was originally part of North Carolina, until ceded to the federal government as the Southwest Territory in 1790.
