Christopher Columbus was a 15th-century navigator and explorer credited with discovering a permanent route linking the shores of the Atlantic Ocean, an achievement that brought once-sundered peoples together in a single network of communication. While widely believed to have been born in Genoa, Italy, his precise origins remain a subject of long-standing debate and recent DNA investigation.Driven by what he believed was divine inspiration and a "grand idea" to reach the Indies by sailing west, Columbus secured Spanish royal sponsorship after being rejected by Portugal. In modern times, he is a deeply controversial figure, often characterized as either a providential hero who promoted civilization or a "villainous" conqueror responsible for the exploitation, enslavement, and decimation of indigenous populations.Though he never reached the mainland of what is now the United States, his 1492 voyage initiated the era of European colonization in the Americas. After centuries of mystery surrounding his travels after death, DNA analysis recently confirmed that his remains are entombed in the Seville Cathedral in Spain
