Most of the show is historically incorrect. First of all season 3 episode 14 they raised "the jolly roger" on the queen Anne's revenge? Blackbeards flag features a skeleton with a spear pointed at a heart and blackbeard was never a coward otherwise he would never die aboard his own ship or made himself look like the ultimate badass he is supposed to be and he had burning fuses around his head and that is only a few examples.
