Texas soon became the center of the Freedom vs Slavery Debate, with thousands of Southerners who owned slaves against the thousands of European Immigrants and Factory Owners from Britain. This map represents the political divisions between the Slavery (Red) Regions and Free (Blue) Regions. In the US, the Republican Party is formed, and becomes very popular. Many former Whigs join the party. Meanwhile, thousands of Southerners still continue to leave the US for Texas. Also, Texas would reach one million people in 1855 thanks to large amounts of immigration from the South and Europe.
