B
HistoryA character grade: shown, never part of Karnes City’s overall grade.
Few Texas towns list much on the Register (a typical Texas town has 0.0 per 10,000 residents, the U.S. 2.4), so Karnes City’s 8.3 sits above most of its state (86% of Texas towns have fewer) while its 3 historic buildings outnumber those of 65% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C+ to B+. The pre-1940 share is a Census survey estimate (±7.4 points). The founding year is the first post office, not a stated founding date.

What stands out about Karnes City’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
In 1894, as a result of a special election, the county seat was moved from Helena to Karnes City. Ten years earlier, Colonel William G. Butler (1831–1912) had blamed Helena and its corrupt mayor for the death of his son, Emmett, who was killed on December 26, 1884, by a stray bullet from a bar fight. Butler, a wealthy rancher, retaliated by arranging for the San Antonio and Aransas Pass Railway, which started construction in 1885, to bypass Helena.
The Karnes City post office opened in 1891, the earliest record of the town by name (U.S. post office records).
