After a grueling trek through dense jungle and hostile territory with about 190 Spaniards and hundreds of indigenous guides, Balboa climbed a ridge in the Darién region and became the first European recorded to gaze upon the Pacific from the New World's shores.

After fierce debate over how to balance federal power with individual liberty, Congress adopted twelve proposed amendments and forwarded them to the states. Ten were ratified by December 1791, becoming the Bill of Rights — guaranteeing freedoms of speech, religion, and the press, the right to bear arms, and protections against unreasonable search and self-incrimination.

Faulkner grew up in nearby Oxford, Mississippi, the town that would become the model for his fictional Yoknapatawpha County. Through novels like The Sound and the Fury, As I Lay Dying, and Absalom, Absalom!, he pioneered stream-of-consciousness techniques in American fiction and wrestled unflinchingly with slavery's legacy, family decay, and the burden of Southern history. He won the Nobel Prize in Literature in 1949.
