After the great decisive battle of the world powers of Marine Ford and the death of Whitebeard there, his former followers, led by the former commander of the first division of the Whitebeard pirate gang, Marco the Phoenix, went into a large-scale, destructive war of retaliation against Blackbeard and his subordinates.
Exact details of how this war unfolded are not known at this time, but it was learned that Marco’s men suffered a crushing defeat. As a result, all of Whitebeard’s crew disappeared without a trace; Blackbeard, on the other hand, was from then on officially recognized as Edward Newgate’s successor among the Four Emperors.
