When our founders created Congress they established a bicameral legislature with one House to Represent the people and a second House to Represent the states.

This model provided for a House of Representatives with membership based on proportional representation and a Senate based on the equal representation of the states. This bicameral legislature prevented the large states from completely dominating the small states.

Bicameral legislatures were established in every state except Nebraska. This was done to prevent the large metropolitan counties from dominating the small rural counties.

In the mid 1960’s as a result of a series of Supreme Court opinions, the states now have a unicameral legislature with two houses with representation based entirely on population. 

The purpose of the bicameral legislature was to prevent the tyranny of the majority, but this Supreme Court opinion resulted in the rural counties losing their voice in their state legislatures.
