The first Spanish mission in California, Mission San Diego de Alcalá, was built in 1769 and founded by a cruel, bloodthirsty priest named Junipero Serra who was infamous for kidnapping, beating, and whipping Indigenous women and children. He would later establish nine of the state’s 21 Spanish Catholic missions and was known to refer to the deaths of Indigenous children as a “harvest.”

Elias Castillo, the author of A Cross of Thorns: The Enslavement of California’s Indians by the Spanish Missions, wrote that Serra would hold the women and children captive and subject them to an “unforgiving regimen that would ultimately claim the lives of 62,000 Indians and devastate their civilizations, including the extinction of a number of small tribes.”

Then, following the Catholic invasion, came the gold-hungry “pioneers.” These white, get-rich-quick prospectors were known as the “49ers,” and tens of thousands of them flooded into California after gold was found at Sutter’s Mill in 1848.

According to anthropologists, in 1769 that area of the Pacific Coast was populated with at least 350,000 Indigenous people. By 1849, following 80 years of massacres, battles, removal, and rampant European diseases unfamiliar to Indigenous immune systems, the number of Indigenous people fell to 150,000. And by 1879, according to The New York Times, the population had fallen to 30,000 people. In one generation, the Indigenous share of California’s population fell from 90 to 1 percent.

Indeed, while the state did essentially everything it could to realize the genocide of the state’s Indigenous people, so did the 49ers themselves. The white prospectors hunted, murdered, and enslaved Natives. They raided tribal outposts, scalped the men, women, and children, and were paid for all the scalps and horses they took.

Thousands of Indigenous children were bought and sold as slaves. California’s governor and the legislature coordinated this attempted extermination of Natives. The state spent millions on bounties and militias to annihilate the original peoples of California. And millions of dollars in the mid-19th century is no small amount. Just $2 million in 1848 is the equivalent of nearly $78 million today.

But Republicans are wont to argue that there’s never been a genocide of Indigenous people anywhere in the United States. In 2012, during a hearing on the genocide of Natives at the Colorado State Capitol, then–state legislator Ellen Roberts said she could not sign on to the resolution because she disagreed with the language.

“When I look up the word ‘exterminate,’ it is to destroy totally,” she argued. “And my problem with this resolution is I thank God that we have not destroyed totally the Native American people. And one of my challenges…is [the] wording; that is as if they are extinct, because they are not.”

But the word “genocide” does not mean “destroyed totally,” according to the word’s creator, Raphael Lemkin. A Polish lawyer who was able to escape Poland when the Nazis invaded in 1939, he said the term is intended “to signify a coordinated plan of different actions aiming at the destruction of essential foundations of the life of national groups, with the aim of annihilating the groups themselves.”

This is a demonstration of what Vine Deloria Jr., the late Lakota scholar and activist, called the act of “deliberate forgetting” in America, posited in his book Red Earth, White Lies. It’s this deliberate forgetting that has allowed so many fans of the red and gold to overlook the team’s name since its founding in 1946.

At the California State Legislature, Assembly member James C. Ramos has introduced a bill that would require the state’s K-12 curriculum to accurately tell the story of the genocide of the state’s first peoples.

“It would require more accurate instruction about the impact of the mission and Gold Rush history on California’s tribes,” Ramos said in a statement. “It’s time for us to stop romanticizing and glorifying eras that almost decimated the state’s Indians.”

Meanwhile, the Super Bowl will go on and so will the dehumanization of Indigenous peoples in the form of racist mascots, which have been shown in peer-reviewed research to harm the mental health and well-being of children. Indeed, having an Indian sports mascot is one of the last old-school racist practices that many Americans of every politics, creed, and color will wholeheartedly get behind for their team. And while the Kansas City Chiefs’ official mascot is a wolf, fans don’t arrive wearing wolf ears; they show up at games and tailgates wearing red-face and faux–chicken feather Indian headdresses.

The irony of all this is that the NFL will emblazon the end zone with the words “End Racism,” and the 49ers faithful will go on not knowing the evil that was done by the actual 49ers. The decent thing for the team to do would be something, anything, that acknowledges the true history of the 49ers. Perhaps the organization could more accurately depict their mascot, Sourdough Sam—transform him from a jolly gold hunter to a hunter of Natives. Then maybe the fans would be forced to confront the dark history of the 49ers.
