Final answer:
The guaranteed representative form of government in 1824 is related to the Mexican Federal Constitution of 1824, which established Mexico's federal structure and influenced later events leading to the Texas Declaration of Independence.
Step-by-step explanation:
The Mexican federal Constitution of 1824 guaranteed a representative form of government, as stated in the historical context. This relates to the Mexican Federal Constitution of 1824 itself, which marked a compromise between liberal and conservative interests and established social equality except for military and clergy privileges. It created a federal government structure with the power to pass laws and tax, and led to Guadalupe Victoria becoming Mexico's first president. When the conservative Santa Anna later overthrew this constitution, it prompted the Texans to defend the principles of the 1824 Constitution, eventually leading to the Texas Declaration of Independence and the formation of the Republic of Texas.
