1. Slavery might have continued for longer: One of the reasons that Texas was annexed by the United States was to expand the territory of the country and to bring in more slave states. Texas had already established slavery, and its leaders were in favor of continuing it. If Texas had remained independent, it is possible that slavery might have continued there for longer than it did in the United States. This could have had a ripple effect on the debate over slavery in other parts of the country, potentially delaying the Civil War or changing its outcome.
2. The United States might not have expanded westward as quickly: Texas was an important part of the westward expansion of the United States in the 19th century. If Texas had remained independent, it is possible that other areas of the West might have been less likely to join the United States. For example, California, which was annexed by the United States in 1850, might have remained independent or joined a different country instead. This could have slowed the westward expansion of the United States and changed the country's geography and demographics
