Many observe Columbus Day in the United States on the second Monday in October.

The first known celebration honoring the First European's discovery of America was October 12, 1792. This took place in New York city. It was intended to celebrate the 300th anniversary of Columbus' landing in the New World. It is said to have been organized by The Society of St. Tammery, also known as the Columbian Order.

The Italian community in San Francisco held their first Columbus Day in 1869.

Later, in 1892, Benjamin Harrison encouraged people to take part in the 400th anniversary of Columbus' first voyage. It was interesting to me that it was during this occasion that the pledge of allegiance was recited publicly for the first time. (That pledge that was written by Frances Bellamy)

President Roosevelt later proclaimed October 12 as Columbus Day. President Nixon later declared the second Monday in October to be a national holiday. That was in 1971. Hope you found this information at least somewhat interesting, like I did.
