Will we ever have an undisputed heavyweight champion again?

The last time we had an undisputed heavyweight champion the Duke of Normandy (William The Conqueror or William I) defeated King Harold Godwinson (Harold I) at the Battle of Hastings in 1066 which is depicted on the Bayeux Tapestry with Halley's Comet, Edward The Confessor and Harold and all that, William commissioned the ancient document/survey the Domesday Book in 1086 and commissioned the Tower of London in 1078, King Harold defeated Hardrada at the Battle of Stamford Bridge one month before the Battle of Hastings, William The Conqueror's half brother Bishop Odo commissioned the Bayeux Tapestry in 1066 and then the Plantagenets Richard The Lionheart (Richard I) fought against Saladin in the series of battles The Crusades in 1193 (Crusades started were from 1095 - 1291) for the Holy Land before Saladin and Richard put down a Truce and there being a King's Ransom for Richard in 1194 before he died in 1199 and his brother John ascending the throne and sealing the Magna Carta (great charter in Latin) in 1215 at Runnymede before losing the Crown Jewels in the Wash and then dying in 1216 and Henry III ascending the throne. Okay it hasn't been that long but it has been a long time since we had an undisputed heavyweight champion lol.
