Represent with one of our original Tumbleweed TexStyles' designs paying our respects to Texas history. The Republic of Texas (República de Tejas) was a sovereign state in North America that was founded on March 2, 1836 by Texans and existed until February 19, 1846. This is why we celebrate Texas Independence Day on March 2. The Republic included parts of Oklahoma, Kansas, Colorado, Wyoming, and New Mexico. Our t-shirt is a 60/40 cotton polyester softstyle blend.
