The history of Texas is very complex. From first being part of the Hispanic empire, the state became Mexican in 1821. With colonization and war Texas joined the United states in 1848. The state has, in other words, long been a huge reservoir for streams of races and cultures. For the bands of prehistoric hunters, for the waves of Indian tribes, for the Spanish and Mexican pushing northward, for the Anglo-Americans from the North and East, and for colonizers who came directly to Texas from Europe, there was more than enough room for settlement (Source: Britannica).
It was the settlements that marked the period, and especially the Anglo-Americans played an important role in history of Texas. In 1830 there were 30,000 Anglo-Americans in Texas, about tentimes as many as Mexicans. The immigration continued as the total population in the USA increased rapidly. There were two movements of Anglo-American settlers in the nineteenth century. The first movement started in the early 1820`s with settlers from Tennessee, Kentucky, Arkansas and Missouri, from now on called Upper South. The second after the Texas revolution in 1836 mainly from the Gulf Coastal Plain states of Alabama, Georgia, Mississippi and Louisiana, Lower South. These movements are in many ways different, and they both have had a big influence on Texan history and the Texan population up till this day.
The issue for discussion: What difference had these two Anglo-American movements economic, political and cultural.
