TEXIAN. The term Texian is generally used to apply to a citizen of the Anglo-American section of the province of Coahuila and Texas or of the Republic of Texas. Texian was used in 1835 as part of the title of the Nacogdoches Texian and Emigrant's Guide. As president of the Republic, Mirabeau B. Lamar used the term to foster nationalism. Early colonists and leaders in the Texas Revolution, many of whom were influential during the Civil War and who were respected as elder statesmen well into the 1880s, used Texian in English and Texienne in French. However, in general usage after annexation, Texanqv replaced Texian. The Texas Almanac still used the term Texian as late as 1868.
