American settlers in the present-day region of West Florida, feeling marginalized under Spanish control, led a revolt against Spanish governance in early October 1810. The settlers were primarily motivated by economic aspirations and the desire for self-determination, following the precedents set by the Louisiana Purchase and the growing spirit of expansionism throughout the United States. With support from the nearby American population and whispers of U.S. backing, they declared independence on October 27, 1810, as the Republic of West Florida. The declaration indicated a strong desire to join the United States, reflecting the broader trend of territorial expansion fueled by American ideals of Manifest Destiny.Following the declaration, U.S. military action reinforced the settlers' claim. Major William James led a small force to seize control of the existing Spanish fortifications, and within days, the American flag was raised at key locations in the region. The quick military and diplomatic maneuvers revealed how the U.S. viewed West Florida as strategically important. By the end of the year, the U.S. government formally recognized the new territory, which was soon incorporated into the United States as the Florida Territory in 1822. This rapid annexation showcased America's growing power in the region and appetite for expansion at the time.
