I was curious about the origins of Columbus Day, so I looked some stuff up.

Columbus Day Word Origins
On October 12, 1492, Christopher Columbus landed on San Salvador in the Bahamas, sure that he had reached the East Indies. King Ferdinand and Queen Isabella of Spain sponsored his trip west to search for a faster trade route to the Orient. Up until the end of his life (1506), Columbus believed that he had found that route. The anniversary of his landing was formally celebrated for the first time by the Society of St. Tammany, also known as the Columbian Order, in New York City on October 12, 1792.
...and in case you feel like reading about Christopher,
here's a link to Encarta's online entry about him.
Now I think I'm going to read some pages in A People's History of the United States, Howard Zinn.
