Final answer:
Texas did not immediately join the United States in 1836 due to fears of war with Mexico and the potential consequences.
Step-by-step explanation:
In 1836, Texas did not immediately join the United States because Congress feared that giving statehood to Texas might lead to war with Mexico. At the time, Texas was an independent republic and had declared independence from Mexico in 1836. The United States, with its own tensions and conflicts, did not want to antagonize Mexico further by officially incorporating Texas as a state. This fear of war with Mexico and the potential consequences led to the delay in Texas joining the United States.
