This article explores the role played by a growing community of Mexican national entrepreneurs who are crafting a new form of Mexican nationalism in San Antonio, Texas. This population of Mexican business people is growing in size and influence in the city. The experiences of Mexican entrepreneurs differ from understood forms of Mexican immigration and acculturation to the United States. They differ from previous waves of affluent groups of political and religious Mexican refugees that flourished in San Antonio from 1908 through the 1940s. The integration and cultural adaptation experiences of Mexican entrepreneurs represent a new form of Mexican nationalism that engages both Mexican and American nationalisms in a bidirectional acculturation process. Blending attitudes, values, beliefs, and behaviours of both countries represent a new form of Mexican and American culture emerging in San Antonio at the beginning of the twenty-first century. To better understand the experiences and dynamics of these business people, this study builds on Pierre Bourdieu's principles of capital and power.
