<P> Three major types of issues were addressed by the Compromise of 1850: a variety of boundary issues, the status of territory issues, and the issue of slavery . While capable of analytical distinction, the boundary and territory issues were actually included in the overarching issue of slavery . Pro-slavery and anti-slavery interests were each concerned with both the amount of land on which slavery was permitted and with the number of States in the slave or free camps . Since Texas was a slave state, not only the residents of that state but also both camps on a national scale had an interest in the size of Texas . </P> <P> The general solution that was adopted by the Compromise of 1850 was to transfer a considerable part of the territory claimed by the state to the federal government; to organize two new territories formally, the Territory of New Mexico and the Territory of Utah, which expressly would be allowed to locally determine whether they would become slave or free territories, to add another free state to the Union (California), to adopt a severe measure to recover slaves who had escaped to a free state or free territory (the Fugitive Slave Law); and to abolish the slave trade in the District of Columbia . </P> <P> The independent Republic of Texas won the decisive Battle of San Jacinto (April 21, 1836) against Mexico and captured Mexican president Antonio Lopez de Santa Anna . He signed the Treaties of Velasco, which recognized the Rio Grande as the boundary of the Republic of Texas . The treaties were then repudiated by the government of Mexico, which insisted that it was sovereign over Texas and promised to reclaim the lost territories . To the extent that there was a de facto recognition, Mexico treated the Nueces River as its northern boundary control . A huge, largely - unsettled area was between the two rivers . Neither Mexico nor the Republic of Texas had the military strength to assert its territorial claim . On December 29, 1845, the Republic of Texas was annexed to the United States and became the 28th state . Texas was staunchly committed to slavery, with its constitution making illegal for the legislature to free slaves . With the annexation, the United States inherited the territorial claims of the former Republic of Texas against Mexico . The territorial claim to the area between the Nueces River and the Rio Grande and Mexican resistance to it both led to the Mexican--American War . On February 2, 1848, the war was concluded by the Treaty of Guadalupe Hidalgo . </P> <P> Among its provisos was the recognition by Mexico of the area between the Nueces River and the Rio Grande as part of the United States . </P>
