Final answer:
The tensions preceding the Texas Revolution were fueled by cultural differences, issues surrounding slavery, and the ambitions of American settlers in Mexican-controlled Texas.
Step-by-step explanation:
The assertion that the 'spark that will start the conflagration (fire) that will deprive us of Texas will start from this colony' alludes to the tense sociopolitical atmosphere that existed prior to the Texas Revolution.
The frustration with Mexican laws, especially those pertaining to slavery, along with the desire for autonomy and expansionist ambitions of American settlers, led to increasing tensions in the region.
Due to divergent cultural practices, the reluctance of Texans to adhere to Mexican laws, and the support for slavery which was against Mexican ideals, conflict was inevitable.
The insurrection against Mexican control, including events such as the Revolt of Fredonia, indicated the growing restlessness of Texans. This coupled with the Mexican government's inability to enforce its laws effectively, and concerns over Texas possibly allying with Britain, made the Texan drive for independence palpable.
Ultimately, this tension resulted in the Texas Revolution and led to the eventual declaration of independence as the Republic of Texas, also known as the Lone Star Republic, in 1836.
Afterward, the population growth accelerated, especially with American slaveholders bringing enslaved Africans to the region to circumvent Mexico's anti-slavery stance. The substantial increase in the Lone Star Republic's population and the region's economic aspirations eventually positioned it for annexation by the United States, which occurred in 1845.
