Final answer:
The statement that the Battle of Goliad was caused by the immigration of thousands of Americans to Mexico around 1835 is false. The battle was a part of the Texas Revolution, which was a result of long-standing tensions between American settlers and the Mexican government.
Step-by-step explanation:
The statement that the battle of Goliad was caused by the immigration of thousands of Americans to Mexico around 1835 is false. Although the growing presence of American settlers in Texas, their reluctance to abide by Mexican law, and their desire for independence were significant factors leading up to the Texas Revolution, the Battle of Goliad occurred in 1836 and was part of the larger conflict between Texan colonists and the Mexican government. The tensions arose due to various factors including cultural and religious differences, the issue of slavery, and the American settlers' expectation that Texas would eventually become part of the United States.
Following the Mexican government's attempts to stem American immigration and outlaw slavery, American and Texan dissatisfaction grew. The event became part of the Texas Revolution, which led to the declaration of independence by the Republic of Texas or the Lone Star Republic. The influx of American settlers began way before 1835, starting in 1821, and by 1835, the number of Anglo-Americans in Texas had already reached twenty thousand.
It is important to note that while a large number of Americans moved to Texas after events like the fall of the Alamo, seeking land and economic opportunities, the Battle of Goliad itself was more directly related to the burgeoning desire of Texans to seek independence from Mexico, a culmination of long-standing tensions.
