What role did regulation of trade play in the conflict between texans and mexico

MEXICAN TEXAS. The Mexican war of independence (1810–21), one of the rebellions that erupted throughout Latin America to overthrow Spanish colonial rule, left Mexico with an array of problems that touched upon events in the far northern Mexican province of Texas. Economically, the country faced devastation in 1821. It stood in marked contrast to the rich colony that had promised great potential towards the end of the colonial era. Money barely circulated. Once-rich mines struggled to regain their former efficiency. Ranches and farms were no longer productive. With the economy in shambles, thousands faced unemployment. Entire areas experienced depopulation as people sought out a livelihood elsewhere. Moreover, differences over class distinctions split the nation as the landed gentry, the military, and church officials sought the preservation of the antebellum order, wherein they ruled alongside government. Additionally, many of the country's new leaders had had little prior experience in governing.
