Final answer:
Texans were affected by Mexican independence through cultural and political clashes with the Mexican government, leading to Texas's own declaration of independence and the establishment of the Lone Star Republic, where slavery was allowed, compounding tensions that eventually escalated into the Mexican-American War.
Step-by-step explanation:
Following Mexican independence, Texans experienced significant political, cultural, and economic changes. The establishment of the Lone Star Republic marked a transitional period, during which tens of thousands of American immigrants flooded into Texas, enticed by land grants and the possibility of future annexation by the United States. Despite Mexican government efforts to integrate Americans through laws and land incentives, Texans remained culturally distinct and economically competitive, dominating local governments and flouting Mexico's anti-slavery legislation. This culminated in Texas declaring independence from Mexico in 1836, and adopting a constitution that allowed slavery, which further distanced Texans from Mexican rule and policy. The eventual annexation of Texas to the United States would heighten tensions leading to the Mexican-American War.
The Mexican government tried several approaches to assert control over Texas, like outlawing slavery in 1829 and promoting Mexican immigration to reduce American influence. However, these measures failed and instead provoked the Texans. The American settlers in Texas, many of whom held the view that Texas was destined to join the United States, largely rejected Mexican identity and governance, which contributed heavily to the push for independence and eventual statehood.
