Samuel Spencer was a member of the Colonial Assembly at an early day, and in 1774 elected to the Provincial Congress at New Berne, which was the first organized movement of the people in a legislative capacity in open opposition, and independent of the Royal Government. This body sent delegates to the Continental Congress at Philadelphia.
It may be interesting for reference, to note the Provincial Congresses, the place and time from the first to the last, which formed the Constitution.

He was repeatedly elected to the State Congresses, and in 1777 was chosen one of the three judges of the Superior Courts, first elected under the State Constitution, which elevated position he held until his death.
