Step-by-step explanation:
The largest ethnic group in Texas derived directly from Europe was persons of German birth or descent. As early as 1850, they constituted more than 5 percent of the total Texas population, a proportion that remained constant through the remainder of the nineteenth century. Intermarriage has blurred ethnic lines, but the 1990 United States census revealed that 1,175,888 Texans claimed pure and 1,775,838 partial German ancestry, for a total of 2,951,726, or 17½ percent of the total population. By this count, Germans rank behind Hispanics and form the third-largest national-origin group in the state. Most persons of German descent do not regard themselves as ethnic Germans, however. From their first immigration to Texas in the 1830s, the Germans tended to cluster in ethnic enclaves. A majority settled in a broad, fragmented belt across the south central part of the state. This belt stretched from Galveston and Houston on the east to Kerrville, Mason, and Hondo in the west; from the fertile, humid Coastal Plain to the semiarid Hill Country. This German Belt included most of the Teutonic settlements in the state, both rural and urban.
The German Belt is the product of concepts and processes well known to students of migration, particularly the concept of "dominant personality," the process called "chain migration," and the device of "America letters." Voluntary migrations generally were begun by a dominant personality, or "true pioneer." This individual was forceful and ambitious, a natural leader, who perceived emigration as a solution to economic, social, political, or religious problems in his homeland. He used his personality to convince others to follow him in migration. In the case of the Texas Germans, Friedrich Diercks, known in Texas under his alias, Johann Friedrich Ernst, was the dominant personality. Ernst had been a professional gardener in the Grand Duchy of Oldenburg in northwestern Germany. He immigrated to America intending to settle in Missouri, but in New Orleans he learned that large land grants were available to Europeans in Stephen F. Austin's colony in Texas. Ernst applied for and in 1831 received a grant of more than 4,000 acres that lay in the northwest corner of what is now Austin County. It formed the nucleus of the German Belt.
