What did Martin Luther king do that was important and how does it relate to everything that goes on today(black lives matter, all of that stuff) (Ik what he did obviously but Ian how to put it in essay form and please don’t jus copy and paste❤️)

Martin Luther King jr.  helped with the civil rights movement.  He worked so hard for the civil rights movement because the colored people were not treated fairly, and didn't get the stuff they deserved.  The reason why BLM relates with MLK and the civil rights movement is because of Jeorge Floyds death that police officer shouldn't have choked him when he said I can't breath that police officer didn't listen just like they did years ago to the colored in the civil rights movement.
