The Southern border of Texas was set so Texas could continue slavery
The Western border of Texas was set so Texas could continue slavery
Slavery did play a significant role in the shaping of Texas's boundaries. However, it is important to note that the overall process of shaping Texas's boundaries was influenced by various economic, political, and social factors in addition to slavery.
The northern border of Texas, which is commonly known as the Red River boundary, was established through the Adams-Onís Treaty of 1819. Slavery was not the primary motive for setting this boundary, as the issue of slavery in the United States was still evolving at that time. The establishment of the northern border aimed to resolve territorial disputes between the United States and Spain, and later Mexico, over the land that would become Texas.
The southern border of Texas, which is formed by the Rio Grande River, also has ties to slavery. The extension of Texas's boundaries to include land south of the Nueces River, known as the Rio Grande boundary dispute, was influenced by the desire to expand and protect slavery. Annexation proponents argued that Texas had historically claimed the Rio Grande as its border, which would allow for the continuation of slavery in the new territory. This dispute ultimately led to the Mexican-American War and the establishment of the Rio Grande as the southern border of Texas.
The western border of Texas was initially defined by the Adams-Onís Treaty and later adjusted through other agreements. The primary motivations for setting the western boundary were the desire to secure access to resources, such as the fertile lands of the Trinity River Valley, and to establish control over territory to maintain and expand the Texas economy. Slavery did play a role in the economic growth of Texas, and the desire to continue the institution in these territories may have influenced some individuals involved in the boundary negotiations.
Overall, while slavery influenced the shaping of Texas's boundaries to some extent, it was not the sole determinant. There were a multitude of factors, including economic, political, and social considerations, that shaped the boundaries of Texas.
