The "Lady of Guadalupe" refers to an important religious figure in Catholicism, particularly in Mexico. She is believed to be an apparition of the Virgin Mary, who appeared to Juan Diego, an indigenous man, in 1531 on the hill of Tepeyac. This event is celebrated as a significant moment in the spread of Christianity in the region. The image of the Lady of Guadalupe is characterized by her dark skin and is often depicted wearing a blue mantle adorned with stars. She is considered the patroness of Mexico and is a symbol of unity and cultural identity for many Mexicans and people of Mexican descent around the world.
