Historically, Texas culture comes from a blend of Southern (Dixie), Western (frontier), and Southwestern (Mexican/Anglo fusion) influences, varying in degrees of such from one intrastate region to another. Texas is placed in the Southern United States by the United States Census Bureau. A popular food item, the breakfast burrito, draws from all three, having a soft flour tortilla wrapped around bacon and scrambled eggs or other hot, cooked fillings. Adding to Texas's traditional culture, established in the 18th and 19th centuries, immigration has made Texas a melting pot of cultures from around the world.
