what present day states were included in the boundaries of the republic of texas
1. before the war, Mexico refused to recognize the Rio Grande as the boundary and insisted that the Nueces River was the boundary 2. boundary with New Mexico, as a republic, Texas claimed the Rio Grande as its southern and western boundaries giving it control of about 1/2 of New Mexico 3. Many people in Santa Fe didn't want to become part of Texas and many people in the Northern states didn't want slavery introduced here so the Pierce Act was a compromise
