Frida Kahlo was a Mexican painter known for her many portraits, self-portraits, and works inspired by the nature and artifacts of Mexico. Inspired by the country's popular culture, she employed a naïve folk art style to explore questions of identity, postcolonialism, gender, class, and race in Mexican society. Her paintings often had strong autobiographical elements and mixed realism with fantasy. In addition to belonging to the post-revolutionary Mexicayotl movement, which sought to define a Mexican identity, Kahlo has been described as a surrealist or magical realist.

Born to a German father and a mestiza mother, Kahlo spent most of her childhood and adult life at La Casa Azul, her family home in Coyoacán—now publicly accessible as the Frida Kahlo Museum. Although she was disabled by polio as a child, Kahlo had been a promising student headed for medical school until she suffered a bus accident at the age of eighteen, which caused her lifelong pain and medical problems. During her recovery she returned to her childhood hobby of art with the idea of becoming an artist.

The Gettysburg Address is a speech that U.S. President Abraham Lincoln delivered during the American Civil War at the dedication of the Soldiers' National Cemetery in Gettysburg, Pennsylvania, on the afternoon of Thursday, November 19, 1863, four and a half months after the Union armies defeated those of the Confederacy at the Battle of Gettysburg. It is one of the best-known speeches in American history.

Not even the day's primary speech, Lincoln's carefully crafted address came to be seen as one of the greatest and most influential statements of American national purpose. In just 271 words, beginning with the now iconic phrase "Four score and seven years ago,"‍ referring to the signing of the Declaration of Independence 87 years earlier, Lincoln described the US as a nation "conceived in Liberty, and dedicated to the proposition that all men are created equal," and represented the Civil War as a test that would determine whether such a nation, the Union sundered by the secession crisis, could endure. He extolled the sacrifices of those who died at Gettysburg in defense of those principles, and exhorted his listeners to resolve
