a study performed by the University of Texas at Austin, researchers found that those who most strongly identified as "Texan" were not only those who were born and raised in Texas, but also those who immigrated to Texas from another state as a young child. "The fact that both native-born Texans as well as those who came to Texas from another state as children are so much more likely to strongly identify with Texas than the other groups suggests that Texas identity is in large part forged in school, especially in grades 4 through 7 when students are required to study Texas history in social studies class." Texas law requires that the pledge of allegiance to the United States flag as well as the pledge of allegiance to the Texas flag be said on a daily basis, followed by a moment of silence. Portrayals of Texas pride manifest themselves in visible ways such as "Don't Mess With Texas" t-shirts, Texas-shaped jewelry, tattoos, signs, and phrases.
