Final answer:
The resolutions concerning immigration, statehood for Texas, and the removal of import taxes were written by the Conventions of 1832 and 1833, which opposed Mexican policies under President Santa Anna and eventually led to the declaration of the Lone Star Republic in 1836.
Step-by-step explanation:
The resolutions to resume immigration from the US, establish separate statehood for Texas (from Coahuila), and remove import taxes (tariffs) were written by the Conventions of 1832 and 1833. These conventions were a response to Mexican policies that the settlers in Texas found burdensome, particularly those that suppressed immigration from the United States and imposed customs duties, which hampered their economic prosperity. In early April 1833, delegates reconvened to write a constitution for an independent Texas, a constitution that would address issues like jury trials, representation, and fewer restrictions on commerce. However, Mexican President General Antonio Lopez de Santa Anna agreed to all of their demands except for separate statehood.
Eventually, the increasing centralization of power under Santa Anna, including the dissolution of state governments and establishment of a more conservative constitution (the Siete Leyes), led to increased tensions. Texans and other Americans in the region sought to defend the earlier Mexican Constitution of 1824 against Santa Anna’s centralist policies, ultimately leading to Texas's declaration of independence and the formation of the Lone Star Republic in 1836.
