Setting the Scene: A Nation That Swallowed a Continent
📖 Setting the Scene: A Nation That Swallowed a Continent
In 1789, the United States was a thin strip of land clinging to the Atlantic coast — thirteen former colonies with a combined population of around 4 million people. To the west lay an immense unknown: millions of square miles of plains, mountains, rivers, and desert, home to hundreds of Native American nations who had lived there for thousands of years.
By 1890, just one hundred years later, the United States stretched from the Atlantic to the Pacific. It had absorbed Louisiana, Texas, California, and everything in between. It had fought a catastrophic civil war to decide whether human slavery would survive. It had built a transcontinental railroad that cut the journey from New York to California from six months to six days. It had driven millions of Native Americans off their ancestral lands, killed the vast buffalo herds they depended on, and confined the survivors to reservations.
How did a young republic transform itself into a continental giant in just one century? And who paid the price?
History glossary
- What was Manifest Destiny?
- The belief, coined by journalist John O'Sullivan in 1845, that it was God's plan for the United States to expand across the entire North American continent. It provided moral justification for displacing Native peoples, annexing Texas, and fighting the Mexican-American War. Millions of Americans genuinely believed in it as a divine mission.
The new United States was hungry for land from the start. The belief that America was destined to expand westward drove policy for the entire 19th century.
