Also, history textbooks are massively dishonest to you, and it's a good rule of thumb to read history independent of what you're taught in schools. There were so many things deliberately withheld from me in my high school education, like the Tulsa Massacre, the Battle of Blair Mountain, Haymarket Square, etc. etc. etc.
They didn't even teach you that Columbus was plotting to destroy and rob the native people after their first meeting, and wrote about it in his diary. We're very fortunate that Bartolome De Las Casas made a copy of Columbus' diary or we may never have known.
