What was migration to south Texas like in the 1900s?

Unlike most southern states, Texas has been a migration magnet throughout its history, which helps explain the record of growth that now makes it the second most populous state following California. Migration, most of it illegal, from Tennessee, Alabama, and Mississippi fueled the rebellion that wrestled the province from Mexico in 1836. In the decades that followed, an enormous number of southerners, many enslaved, moved west to expand the cotton belt. The 1860 census counted 169,000 enslaved persons, roughly 30% of the state population. After the civil war, whites continued to arrive from nearby southern states, causing the population to double by 1880 and double again in the following twenty years. African Americans contributed little to this late 19th century migration. Migration continued from the same southern states in the 20th century albeit at a somewhat reduced rate. Black Louisianans crossing the border into southeast Texas added the only new dimension to the state's African American population.
