In the Louisiana Constitution of 1846 the Lieutenant Governor of Louisiana assumed the functions of the senate presidency. This arrangement lasted until 1976. The first lieutenant governor to preside over the Senate was Trasimond Landry who served from 1846 until 1850. During the Civil War there were two lieutenant governors, one union, and one confederate, as there were two separate state governments. During the Reconstruction the post was held by Republicans, thereafter the chair was held by Democrats for over a hundred years.
