The Battle of Gettysburg, fought from July 1 to July 3, 1863, was a pivotal turning point in the American Civil War. This battle marked the most significant and bloodiest conflict of the entire war, resulting in a Union victory that halted Confederate General Robert E. Lee's invasion of the North. The outcome also boosted Northern morale and marked the beginning of a shift in momentum towards the Union forces. The battle's importance is further underscored by President Abraham Lincoln's Gettysburg Address, which emphasized the principles of human equality and the American dedication to a unified nation.
