Final answer:
The statement refers to the Texas Declaration of Independence marked by the drafting of a new constitution in 1836 after declaring independence from Mexico. Differences between Anglo-American settlers and tejanos contributed to tensions that led to the Texas Revolution. The Texans achieved independence following their victory at the Battle of San Jacinto.
Step-by-step explanation:
The statement 'After declaring independence from Mexico, Anglo-American settlers in Texas established civil, political, and religious freedom' pertains to the historical event known as the Texas Declaration of Independence. This event took place on March 2, 1836, when the Consultation delegates declared independence from Mexico and drafted a constitution that outlined their vision for the new nation, which included an American-style judicial system, the election of government officials, and the significant determination that slavery would not be prohibited in Texas. Anglo-American settlers were typically unlike tejanos in that many were slave owners and they remained religiously distinct from the largely Roman Catholic tejanos.
The Texans' hopes for independence were finally realized after they defeated the army of General Antonio Lopez de Santa Anna at the Battle of San Jacinto, which is the correct answer to the question about the historical event where Texans defeated Santa Anna's army.
