The Jack County Courthouse, Jacksboro, Texas. Designed by Wichita Falls firm Voelcker & Dixon and partially funded by the Public Works Administration, the courthouse was built in 1940. This richly textured and finely detailed building is an excellent example of Texas’s early modern courthouses. © J. Stephen Conn, 2009.


The Vexillological Association of the State of Texas is a non-profit, non-political organization devoted to researching, preserving, and publicizing the history and use of flags in Texas. Please visit our online exhibits and learn more about how Texans use flags to express our cultural, social, and political identities.

What is Vexillology?

A systematic study of flags and their meanings

“Vexillology is the scientific study of the history, symbolism and usage of flags or, by extension, any interest in flags in general.” Whitney Smith, Flags Through the Ages and Across the World 31 (McGraw-Hill 1975).

The origin of the word

“The word vexilloid comes from the Latin word ‘vexillum,’ meaning flag, and it is from this root that the words vexillology (the study of flags), vexillologist (a flag historian), vexillophilist (a flag collector), and vexillary (a flag bearer) are derived.” Robert M. Jarvis, The History of Florida’s State Flag, 18 Nova L. Rev. 1037, 1039 n.8 (1994)
