How are u.s territories different from one of the 50 states?

The difference between a U.S. territory and a U.S. state is they don't have any elected body of representatives and there is no representation in Congress.

Progressives were interested in establishing a more transparent and accountable government which would work to improve U.S. society. These reformers favored such policies as civil service reform, food safety laws, and increased political rights for women and U.S. workers.
