Long after the United States abolished slavery in 1865, Black Americans still face systemic racism. There are several events in American history that point to the lasting impact of slavery and the Tulsa Race Massacre is an important one for students to learn about. Unfortunately, Oklahoma is the only state that requires the teaching of this devastating historical event in public schools, and the official legislation to make the curriculum universal across the state only began this year.
It was primarily that FDR thought such a willingness to help the cause of minorities during the 1930s would "turn off" members of Congress, whom he needed to help pass his New Deal legislation.
It was a mixture of various reasons, although for the Spanish and Portuguese it was a question of reaching India for spice trades after the embargo instated on them by the Ottoman Turks.
The Portuguese went around Africa, and the Spanish tried sailing west across the barren ocean, and accidentally discovered America through Columbus.
