Question

why did the republic of texas have trouble joining the united states? (1 point) because congress believed that texas should really be a part of mexico because southern congressmen who were for slavery did not want another free state because northern congressmen who were against slavery did not want another slave state because congress thought manifest destiny was complete

Explanation:

To determine why the Republic of Texas had trouble joining the US, we analyze each option:

• The first option is incorrect as Congress didn’t see Texas as part of Mexico post - Texas Revolution.
• The second option is wrong because Texas was a slave - holding region, and Southern congressmen would have supported a slave state.
• The third option is correct. Texas allowed slavery, and Northern congressmen (opposed to slavery) didn’t want another slave state, which created issues for Texas's admission.
• The fourth option is incorrect as manifest destiny was about expanding across the continent, and Texas’s admission was still a point of contention related to slavery, not manifest destiny being “complete.”

Answer:

C. because Northern congressmen who were against slavery did not want another slave state
