The era of Abraham Lincoln was marked by seismic shifts in American history. From the outbreak of the Civil War to the issuance of the Emancipation Proclamation, Lincoln led the nation through its darkest hour with unwavering moral clarity. His brief yet powerful Gettysburg Address redefined the purpose of democracy, while his push for the 13th Amendment ensured that freedom would be written into the Constitution. Even in death, assassinated just days after the war’s end, Lincoln’s vision of unity and liberty echoed far beyond his lifetime.
