Question

What kept Texas from becoming a state until 1845?

The Senate tried to override President John Tyler's veto until they finally gained success the fourth time around.

Citizens were fearful that it would trigger a war with Mexico.

Some members of Congress feared it would tip the balance of power toward the slave states.

The U.S. had to wait for California to gain enough people before entering the Union as a free state.

Answer 1

Correct answers:
- Citizens were fearful that it would trigger a war with Mexico.
- Some members of Congress feared it would tip the balance of power toward the slave states.

Why: Mexico never recognized Texas independence, so many feared annexation would provoke war (which it ultimately helped cause in 1846). Also annexing Texas as a slave state threatened the North–South balance in Congress, so many Northerners opposed it.

Why the other choices are wrong:
- The Senate did not keep overriding Tyler’s veto; in fact Tyler supported annexation. A treaty of annexation failed in the Senate in 1844 (it lacked the 2/3 vote), and annexation was later accomplished by a joint resolution in 1845.
- Waiting for California is unrelated: California’s rapid population growth and admission as a free state happened later (1850) and was not a prerequisite for Texas’s admission in 1845.
