When did region 4 become part of the united states

I don’t think that there is a year for when the 4 regions became a part of the US.

it is the code of hammurabi

- "schenck v. united states, case in which the u.s. supreme court ruled on march 3, 1919, that the freedom of speech protection afforded in the u.s. constitution's first amendment could be restricted if the words spoken or printed represented to society a “clear and present danger.” "

- speech aimed to potentially create danger could be banned.
