Boerne is a city in and the county seat of Kendall County, Texas, United States, in the Texas Hill Country. Boerne was named in honor of German author and publicist Ludwig Börne. The population of Boerne was 10,471 at the 2010 census, and in 2018 the estimated population was 17,106.
Boerne came into being as an offshoot of the Texas Hill Country Free Thinker Latin Settlements, resulting from the Revolutions of 1848 in the German states. Those who came were Forty-Eighters, intellectual liberal abolitionists who enjoyed conversing in Latin and who believed in utopian ideals that guaranteed basic human rights to all. They reveled in passionate conversations about science, philosophy, literature, and music. The Free Thinkers first settled Castell, Bettina, Leningen, and Schoenburg in Llano County. These experimental communities were supported by the Adelsverein for one year. The communities eventually failed due to lack of finances after the Adelsverein funding expired, and conflicts of structure and authorities. Many of the pioneers from these communities moved to Sisterdale, Boerne, and Comfort.
