Makeup of the US Senate

Under Article I, Section 3 of the U. S. Constitution senators are elected for a six year term and are divided into 3 classes resulting in 1/3 of the body being elected every two years. After the initial appointments in 1789 following ratification, Class 1 was elected in 1790 and every six years thereafter; Class 2 in 1792 and then every six years; and Class 3 in 1794 and then every six years. Senators were elected by the State Legislatures until the adoption of the 17th Amendment which provided for popular election.
