The largest single immigration of Germans to the United States, and the most unusual, occurred in Texas around the middle of the nineteenth century. The organization formed to direct this German colonization of Texas became popularly known as the Adelsverein (The Society of Noblemen). The key figure in this settlement was Carl, Prince of Solms-Braunfel, appointed Commissioner-General by the Adelsverein. Solms' diary of this time was discovered in documents relating to the Adelsverein and has been translated here for the first time.
