I have a dream . . . of garlic bread?

I received an email this morning from a local pizzeria offering a free medium garlic bread with any order today in recognition of Martin Luther King Day.  While I'm quite sure the intent here is "to sell more pizzas," I can't help wondering if there might be more to it.  Did Dr. King have any Italian ancestry that I've been previously unaware of?  Was there any Italian-American involvement in the civil rights movement?  Did Dr. King even like Italian food?
