Final answer:
During the Civil War era, officeholders in Texas generally supported the positions taken by Southern leaders on the issue of slavery expansion.
Step-by-step explanation:
During the Civil War era, officeholders in Texas generally supported the positions taken by Southern leaders. This is because Texas allowed slavery and its politicians were aligned with the pro-slavery stance of the South. They believed that the government should allow slavery to expand into new territories in the West, similar to the views held by Southerners as a whole. The issues of Texas statehood and the expansion of slavery were major factors that influenced the positions taken by officeholders in Texas during this period.
