Final answer:
Mexican Texans who joined the cause of Texan independence were known as Tejanos. While Tejanos were active early in the struggle, increasing American immigration and differences in views on slavery and religion led many Tejanos to withdraw from the Texas Revolution. American settlers in Texas differed from Tejanos primarily by being slave owners and remaining distinct in their religious practices. The correct answer is B) Tejanos.
Step-by-step explanation:
The majority of the new citizens of the Republic of Texas were indeed former Americans, but there were also significant Mexican Texans who joined the cause of Texan independence. These Mexican Texans were known as Tejanos. After the fall of the Alamo, many Americans came to the aid of their compatriots. Although several companies of Tejanos had been active in the struggle for independence, mounting anti-Mexican sentiment among the increasing number of American settlers led to many Tejanos withdrawing from the revolution.
The American settlers in the Mexican province of Texas differed significantly from the Tejanos. The settlers were mostly slave owners and remained religiously distinct, as they were largely non-Catholic, unlike the Roman Catholic Tejanos.
