Conservatism is a political ideology that emphasizes the value of traditional institutions, practices, and customs, advocating for gradual change rather than radical shifts in society. In the context of the rise of the Republican Party in Texas, conservatism played a pivotal role in shaping the party's principles, focusing on limited government, individual liberties, and a strong emphasis on personal responsibility. This ideology often arose as a reaction to more liberal policies and movements, seeking to preserve established social norms and economic structures.
