What are some reasons given by the Texas Secession Convention for leaving the Union?

Texas Secession Convention ceded from the nation with the argument that it was against the principles of the state to follow the Republican government thus formed.

Explanation:

Texas Secession Convention was one of the main moments of the history of the US that led to the Civil war happening as Texas was a newer state that succeeded rather dramatically with its own governor forced to give up his place as he did not agree to the plan.

It was because the election of the Republicans to senate and Congress made them angry and they knew that the anti slavery sentiment as well as the imposition of tarries on the state were to be levied, the people in the convention wanted out of the deal.
