Who was involved in the annexation of texas?

The annexation of Texas involved several key individuals and groups. These include:

1. Texan Settlers: The Texas Revolution (1835-1836) was led by Texan settlers who fought against Mexican rule and declared independence in 1836. They established the Republic of Texas.

2. Sam Houston: Sam Houston was the commander-in-chief of the Texan forces during the Texas Revolution and later became the president of the Republic of Texas. He played a crucial role in advocating for Texas's annexation to the United States.

3. President John Tyler: John Tyler, the 10th President of the United States (1841-1845), was a strong supporter of Texas annexation. He initiated negotiations with Texas and paved the way for annexation during his term.

4. James K. Polk: James K. Polk was the 11th President of the United States (1845-1849). He campaigned on a platform that included the annexation of Texas, and once in office, secured congressional approval for Texas's annexation.

5. United States Congress: The annexation of Texas required approval from the United States Congress. The Joint Resolution of Congress, passed in 1845, authorized the annexation.

6. Voters of Texas: In the Republic of Texas, voters played a significant role in deciding whether to accept annexation. In October 1845, Texans voted in favor of joining the United States, leading to the formal annexation.

It is important to mention that the annexation of Texas was a contentious issue, as it fueled tensions between pro-slavery and anti-slavery factions in the United States, ultimately leading to the Mexican-American War (1846-1848).
