||After this area was freed of Indians, Garza County was created and named in 1876 for a patriotic family of early Texas. With its ranching population rising from 36 in 1880 to only 180 by 1900, Garza remained attached for judicial purposes to Borden County.
In 1906 Charles William Post (1854-1914), "the cereal king" from Battle Creek, Mich., sought Texas land for development. In the month of March, he and his wife and daughter visited here at the OS Ranch, where a barbecue picnic was given in their honor. In the gathering, Post made a speech suggesting the county be organized for self-government, as he proposed to establish a model farm colony and a modern town.
Cowboys from a wide area were at the OS that day working in spring roundup. Immediately they called an informal election in the bunkhouse. A boy who had won all the money gaming the previous evening now gave a dollar to each voter, to be placed in a fund to defray expenses of a future, legal election. It is said that even the horses voted in favor of the Post proposal. After a petition was filed on May 13, 1907, the election was held and the county organized on June 15, 1907. By that time Post city was being built as county seat. County and city still prosper.
