The current meeting of Congress is one of the most racially diverse in history. About 11% of congressional members identify as Black. A quarter of members from the 118th Congress identify as something other than non-Hispanic white, according to the most recent data from the Congressional Research Service.
Congress is a ways away from 1870, when Rep. Hiram Rhodes Revel of Mississippi was elected to serve as the first Black person in Congress. Revels filled an empty Senate seat and only served a year. It was decades until Black representation really started to grow.
