On April, 3rd, 1968, Martin Luther King Jr. gave his famous “I’ve Been to the Mountaintop” speech in Memphis. In it, he urged African Americans to put their money in black-owned banks. It wasn’t his most famous line, but the message was clear: “We’ve got to strengthen black institutions. I call upon you to take your money out of the banks downtown and deposit your money in the Tri-State Bank. We want a ‘bank-in’ movement in Memphis … We begin the process of building a greater economic base.”
