Review Questions

• What were some of the political controversies surrounding the annexation of Texas, and how did they reflect broader national tensions at the time?
  • The annexation of Texas sparked significant political controversy, primarily due to its implications for slavery and expansion. Many anti-slavery advocates opposed the annexation fearing it would extend slave territory into new states. This contention highlighted the growing sectional divide between Northern free states and Southern slave states. The debate over Texas also reflected broader national tensions over Manifest Destiny and America's expansionist goals during this period.
• How did the annexation of Texas contribute to the outbreak of the Mexican-American War?
  • The annexation of Texas was seen as an aggressive move by the United States, prompting strong reactions from Mexico, which still considered Texas a part of its territory despite its independence. The diplomatic relations soured further when disputes arose over the southern border of Texas. The resulting tensions escalated into armed conflict in 1846 when U.S. forces were sent to protect what was claimed as American territory, leading directly to the outbreak of the Mexican-American War.
• Evaluate how the annexation of Texas influenced American territorial expansion and its implications for U.S.-Mexico relations in the years following 1845.
  • The annexation of Texas was a critical moment in American history that fueled a period of rapid territorial expansion known as Manifest Destiny. Following this event, the U.S. engaged in the Mexican-American War, resulting in substantial territorial gains that extended U.S. borders westward. However, this expansion came at a high cost to U.S.-Mexico relations, which remained strained for decades. The legacy of these actions contributed to ongoing conflicts over boundaries and immigration issues that would shape future interactions between the two nations.
