In 1892, on the occasion of the 400th anniversary of Columbus' landing, President Benjamin Harrison issued a proclamation urging Americans to mark October 12. Some 40 years later, President Franklin Delano Roosevelt set aside Columbus Day as a U.S. holiday. Since 1971, the holiday has been commemorated on the second Monday of October.
Of the indigenous people Columbus encountered on his first voyage, he said "they are an uncommonly simple and honest people, very liberal in bestowing whatever they possess. They are neither sluggish nor rude; on the contrary, they are of an intelligent and piercing mind."
The full account of this voyage is detailed in a 1493 letter that Columbus wrote to Gabriel Sanchez, one of the explorer's financiers.
The online exhibition "1492: An Ongoing Voyage," sets the stage for the period of exploration from 1492 to 1600 and examines the encounters between the American people and European explorers that changed the way these natives led their lives.
Another online exhibition, "American Treasures of the Library of Congress," features Columbus's "Book of Privileges," a collection of documents granting the explorer and his descendants titles, privileges, money and powers.
