America was inhabited already when Columbus blundered his way into the West Indies. They are called the West Indies, in case you didn’t know, because he thought he had sailed all the way around the world to Japan, China, and India. Seriously. He was convinced that San Salvador was Japan, and Cuba was China.
Columbus wasn’t a great thinker. Contrary to what school teachers were still telling us when I was in grade school, Europeans had known for centuries that the world was round. And Pythagoras and Aristotle had both deduced that the Earth was a sphere because of the shape of the Earth’s shadow on the moon during Lunar eclipses. Eratosthenes calculated the size of the Earth pretty accurately based on shadows at different latitudes more than 200 years before the time of Christ (He also correctly deduced the tilt of the Earth’s axis a bit later).
Columbus thought that Eratosthenes was wrong, that the Earth was much smaller, and that it would take only a short time sailing west to reach Asia. He was very wrong. And not just because there were two continents Europe didn’t know about.
And then there was the abominable way the Columbus and the Europeans that followed treated the people who lived here. It was not, as some of my other teachers used to say, merely that the Europeans had more advanced technology. The Europeans were fond of making written agreements with the people who already lived here, and then when it suited them, ignore the agreements and take, kill, or pillage whatever they wanted.
So, yeah, even though I am a pasty-skinned, blue-eyeed white guy with ancestors from places like Ireland, England, and France, count me as one of the people who celebrates Indigenous Peoples Day.
The movement to replace Columbus Day with a holiday honoring Native Americans have been around for a long time. In 1989 the state of South Dakota abolished the state observance of Columbus Day and enacted a Native American Day to be observed on the same day as the Federal Observance fo Columbus Day.
Several other states: California, Nevada, and Tennessee all observe a Native American Day in September (the California holiday first called for by then-Governor Ronald Reagan in 1968, though not enacted into law until 1998).
Governors in Alaska and Vermont (and probably others, but I haven’t found them, yet) have issued proclamations to declare and Indigenous Peoples Day, but neither state’s legislature has enacted it into law, and such proclamation tend to be ceremonial, usually assumed only to apply to the year issued.
On the other hand, a rather huge number of cities and towns all over the country have adopted ordinances replacing Columbus Day with Indigenous Peoples Day. Maybe when more follow more states will join South Dakota.
