Brigadier General Thomas J. Green (1802–1863) was born in North Carolina and served in the North Carolina General Assembly, in the Florida Legislature, and, after the Texas Revolution of 1835–36, in the Congress of the Republic of Texas. In 1842 he was second in command of the ill-fated Mier Expedition, in which 242 Texans were captured. In this essay, Green offered his opinion of how Texas, Mexico, and the United States should foster their diplomatic relations. Green supported the expansion of the United States and war against a corrupt Mexico. Green embraced Manifest Destiny—the notion that American colonists were divinely ordained to conquer and settle the whole continent—and envisioned the United States as a global power.
