In the context of the annexation of Texas by the United States, border disputes played a critical role as the U.S. and Mexico had conflicting claims over the territory, particularly regarding the southern boundary of Texas.
December 29, 1845: December 29, 1845, marks the date when Texas was officially admitted as the 28th state of the United States. This significant event occurred after a prolonged period of independence following the Texas Revolution and was instrumental in shaping the political landscape of North America during the mid-19th century.
Free State Debate: The free state debate refers to the contentious discussions and disagreements regarding whether newly annexed territories, particularly Texas, would enter the Union as free or slave states.

He is best known for his strong support of territorial expansion, particularly the annexation of Texas and the resulting Mexican-American War, which significantly shaped the boundaries of the United States.
Joint Resolution for Annexing Texas: The Joint Resolution for Annexing Texas was a legislative act passed by the United States Congress in 1845 that formally invited the Republic of Texas to join the Union as a state. This resolution was crucial because it bypassed the treaty process, enabling a quicker and less contentious path to annexation. It reflected the growing American sentiment for westward expansion and the desire to incorporate Texas into the United States, amid concerns about potential conflicts with Mexico.
Manifest Destiny: Manifest Destiny is the 19th-century doctrine that the expansion of the United States throughout the American continents was both justified and inevitable. This belief fueled a sense of American exceptionalism and a mission to spread democracy and capitalism across the continent, significantly influencing key events and policies, including territorial acquisitions and conflicts.
March 2, 1836: March 2, 1836, marks the date when Texas declared its independence from Mexico, becoming a sovereign nation. This pivotal moment is crucial in understanding the broader narrative of Texas' relationship with the United States, as it set the stage for future events, including the eventual annexation of Texas into the United States.
Mexican-American War: The Mexican-American War was a conflict between the United States and Mexico from 1846 to 1848, primarily over territorial disputes following the U.S. annexation of Texas.

Nationalist viewpoint: The nationalist viewpoint is an ideological perspective that emphasizes the interests, culture, and identity of a specific nation or group, often advocating for political independence or autonomy. In the context of the annexation of Texas by the United States, this viewpoint played a crucial role in shaping the motivations behind Texas’ desire for independence from Mexico and its subsequent pursuit of statehood in the U.S.
