Manifest Destiny: American Expansion — Reading Comprehension

The concept of Manifest Destiny was a powerful force in 19th-century America. Many Americans believed it was the nation’s duty and right to expand westward across the North American continent. This belief was not just about gaining land, but about spreading American values, democracy, and progress. However, Manifest Destiny also led to serious conflicts with Native American nations, Mexico, and others who lived on these lands.

In the early 1800s, the United States was mostly settled along the Atlantic coast. With the Louisiana Purchase in 1803, the country doubled in size, adding vast new territory west of the Mississippi River. This encouraged people to move west. The government passed laws like the Homestead Act in 1862, making it easier for families to claim and settle land on the frontier. As a result, towns, farms, and new states began to appear in areas that had once been home to Native Americans and wildlife.

Despite the promise of opportunity, westward expansion was filled with challenges. Settlers faced harsh weather, difficult journeys, and conflicts with Native peoples who resisted losing their ancestral lands. The Indian Removal Act of 1830 forced thousands of Native Americans off their homelands, leading to tragedies like the Trail of Tears. Meanwhile, the belief in Manifest Destiny justified wars, such as the Mexican-American War (1846–1848), through which the United States gained vast southwestern lands, including California and Texas.

The consequences of expansion were complex. On one hand, it created economic growth, new opportunities, and helped build the United States into a continental power. On the other hand, it caused displacement and suffering for Native Americans and led to disputes over slavery in new territories. These tensions contributed to the outbreak of the Civil War. The idea of Manifest Destiny continues to shape American identity and debates about the nation’s role in the world.

Historians today encourage us to look at Manifest Destiny from multiple perspectives. While it helped create the modern United States, it also involved difficult choices, losses, and moral dilemmas. Studying this period teaches us about the power of beliefs in shaping history and the importance of considering all voices and experiences.
