Some Italian-Americans observe Columbus Day as a celebration of their heritage, the first occasion being in New York City on October 12, 1866.
Columbus Day was first popularized as a holiday in the United States through the lobbying of Angelo Noce, a first generation Italian, in Denver.
The first official non-centennial Columbus Day was decreed by Colorado governor Jesse F. McDonald in 1905 and made state law in 1907.
In April 1934, at the behest of the Knights of Columbus, Congress and President Franklin Delano Roosevelt set aside October 12 as Columbus Day
and it became a federal holiday in 1970.
Columbus Day coloring pages are a popular activity for early school children to learn about the history of this day.
