Before this, Texas was an independent nation. It had declared independence from Mexico on March 2, 1836. The annexation was a major political event that changed the size of the United States. It also caused deep disagreements about laws and borders.

The history of Texas land involves many different nations. For over 300 years, the area was part of the Spanish Empire. Spanish explorers and settlers arrived in the late 17th century. They built missions and forts to settle the land. Later, the land became part of Mexico. In 1819, the Adams-Onis Treaty settled some borders between the United States and Spain. This treaty established the southern boundaries at the Sabine and Red Rivers.

This agreement meant the United States did not own Texas at that time.

Many American leaders wanted to acquire Texas for many years. Thomas Jefferson believed Texas would become the richest state in the Union. However, there were many reasons why the United States did not act quickly. The U.S. government did not want to start a war with Mexico. Mexico had outlawed slavery and did not recognize Texas as a sovereign country.

Additionally, adding Texas created tension in the U.S. Congress. Texas was a large region where slavery was practiced. Leaders in the Democratic and Whig parties worried about the political balance between pro-slavery and anti-slavery states.

President John Tyler played a central role in the annexation process. In 1843, Tyler decided to pursue annexation on his own. He wanted to gain support for his presidency. He engaged in secret negotiations with the Texas administration. These talks resulted in a treaty of annexation in April 1844.

When the Senate saw the details, they rejected the treaty in June 1844. The Whig party held a majority in the Senate at that time. The news of the treaty also became a major issue in the presidential election of 1844.

The election of 1844 changed the direction of the annexation. James K. Polk ran for president on a platform of Manifest Destiny. This idea supported the expansion of U.S. territory. Polk won the election against the Whig candidate, Henry Clay.

After the election, President Tyler asked Congress to pass the treaty again. This time, the House of Representatives passed an amended bill. The Senate also passed a compromise version of this bill. This version gave the next president options for how to proceed.

On March 1, 1845, President Tyler signed the annexation bill. He offered immediate annexation to Texas on his last day in office. When James K. Polk took office, he encouraged Texas to accept. The people of Texas approved the agreement through a popular vote.

President Polk signed the final bill on December 29, 1845. Texas formally joined the Union on February 19, 1846. This followed a long period of political debate and negotiation.

The annexation of Texas had significant consequences for North America. It led directly to the Mexican-American War in April 1846. This war began because of the disputes over sovereignty and borders.
