Question

Which event took place soon before the U.S annexed texas

Answer 1

1. The U.S. declares war on Mexico. 2. Mexico allows American settlers into Texas.

Answer 2

James Polk became president of the United States soon before the U.S. annexed Texas. One of the points that Polk ran on for the presidency was that he promised to annex Texas after becoming President. This was a point of contention with Mexico, who declared that this would be a precursor to war if the U.S. were to annex Texas.
