After Minneapolis police officer Derek Chauvin murdered George Floyd last year, tens of thousands of people all over the world took to the streets to protest police violence against Black people. And if you look at images from these marches, you will probably start to notice a common color scheme -- one involving a lot of red, black, and green.

When it first came into existence, the flag posed some bold questions about where Black people owed their loyalty: was it to the nations where their lives were demeaned and threatened?
