Yes, there is evidence to suggest that many Conscience Whigs and others believed that the annexation of Texas and the Mexican-American War were part of a conspiracy by the Slave Power to expand slavery and secure its future in the United States. While proving specific intentions and motivations can be challenging, there are several factors that support this belief:

1. Manifest Destiny: The ideology of Manifest Destiny, which emphasized American expansionism and territorial acquisitions, often overlapped with the interests of slaveholders. Many supporters of Manifest Destiny saw western expansion as a way to spread slavery into new territories.

2. Annexation of Texas: The annexation of Texas in 1845, under President James K. Polk, was seen by many as a step towards expanding slavery. Texas was a slave-holding state, and its annexation was seen as an opportunity to extend the reach of slavery into new territories.

3. Wilmot Proviso: In 1846, during the Mexican-American War, David Wilmot, a Democratic congressman, introduced the Wilmot Proviso, which aimed to prohibit the extension of slavery into any territory acquired from Mexico. This proviso was intended to counter the perceived slave power conspiracy behind the war.

4. Slave Power Conspiracy: The concept of a Slave Power conspiracy was a widely held belief during this time. It argued that a group of wealthy, influential slaveholders controlled national politics and were systematically working to expand slavery into new territories. The annexation of Texas and the Mexican-American War were seen as part of this wider conspiracy.

5. Southern politicians' goals: Some Southern politicians openly supported the expansion of slavery into new territories to secure their economic and political power. Figures like John C. Calhoun and Stephen A. Douglas actively promoted the extension of slavery into western territories.

While it is essential to note that not all proponents of expansion shared this perspective, these factors highlight the evidence that supports the belief in a conspiracy by the Slave Power to expand slavery and guarantee its future in the United States.

To determine whether there is evidence to support the theory of a conspiracy by the slave power to expand slavery through the annexation of Texas and the Mexican-American War, we need to examine historical sources and analysis. As an AI language model, I can provide you with a general understanding of the topic and suggest some avenues to explore further.

1. Background on Texas Annexation and the Mexican-American War:
- The annexation of Texas: In 1845, Texas was admitted to the United States as a slave state through a joint resolution in Congress.
- The Mexican-American War: From 1846 to 1848, the United States fought a war with Mexico, resulting in the United States acquiring significant territories in the Southwest.

2. The Slave Power Conspiracy Theory:
- The "Slave Power" concept: The term "Slave Power" referred to the political influence and perceived dominance of slaveholding interests in the United States.
- Beliefs of the Conspiracy Theory: Some abolitionists and opponents of southern slavery argued that politicians from slaveholding states pursued territorial expansion to spread and ensure the survival of slavery.

3. Evidence Supporting the Conspiracy Theory:
- Political motives: Proponents of the conspiracy theory argue that President James K. Polk, a Democrat and a slaveholder, pushed for the annexation of Texas and expansion into Mexican territories to increase slaveholding states' influence in Congress.
- Correspondence and speeches: Some politicians of the time, such as John C. Calhoun, expressed support for territorial expansion as a way to protect and strengthen slavery.
- Wilmot Proviso: Amidst debates over territories acquired during the Mexican-American War, the proposed Wilmot Proviso sought to ban slavery in those territories, leading some to argue that it proved the conspiracy theory.

4. Counterarguments and Complexity:
- While the conspiracy theory gained traction among abolitionists and some members of the Whig Party, it is worth noting that not all opponents of the Mexican-American War shared this view.
- Identifying and evaluating the motives of historical figures can be complex, requiring the examination of various primary and secondary sources, including diaries, speeches, letters, and memoirs.
