Why did the south pass Slave codes ?
Since the colonial period, colonies and states had passed laws that discriminated against free Blacks. In the South, these were generally included in "slave codes"; the goal was to reduce the influence of free blacks (particularly after slave rebellions) because of their potential influence on slaves.

In their views was to protect and preserve slavery. This is the reason why they helped the union in Civil War.
