USA HISTORY

Detailed explanation-1: -On December 29, 1845, Texas became the 28th state in the United States. Formerly part of Mexico, Texas had been an independent country since 1836. Since its independence, Texas had sought annexation by the U.S. However, the process took nearly 10 years due to political divisions over slavery.

Detailed explanation-2: -Border disputes There was an ongoing border dispute between the Republic of Texas and Mexico prior to annexation. Texas claimed the Rio Grande as its border based on the Treaties of Velasco, while Mexico maintained that it was the Nueces River and did not recognize Texan independence.

Detailed explanation-4: -On December 29, 1845, Texas officially became the twenty-eighth state in the Union although the formal transfer of government did not take place until February 19, 1846. A unique provision in its agreement with the United States permitted Texas to retain title to its public lands.

Detailed explanation-5: -Although Mexico’s war of independence pushed out Spain in 1821, Texas did not remain a Mexican possession for long. It became its own country, called the Republic of Texas, from 1836 until it agreed to join the United States in 1845. Sixteen years later, it seceded along with 10 other states to form the Confederacy.
