Final answer:
False. Historically, the contributions of Tejanos in Texas history have often been overlooked or downplayed by Anglo historians.
Step-by-step explanation:
False. Anglo historians have not always maintained an accurate accounting of the Tejano contributions to Texas history. Historically, the contributions of Tejanos (Texans of Mexican heritage) have often been overlooked or downplayed in favor of a more Eurocentric perspective. This has led to a biased and incomplete understanding of Texas history.
