Congress passes the first Indian Trade and Intercourse Act

Date: 
1790
The Act, as modified in 1834, is codified at 25 U.S.C. section 177. The Non-Intercourse Act, which remains substantially the same today, prohibits conveyances of an Indian tribe's interests in land unless the conveyance is negotiated in the presence of a federal commissioner and ratified by Congress.
