Ealdorman
The term ealdorman was replaced by the term earl during the eleventh century.  In the laws of King Canute both ealdormen and earls are mentioned. But there was no distinction made between them. After the Norman conquest of England in 1066, the title Earl was no longer interchangeable with dux or princeps. They were written at times as comes (count). King William replaced most Anglo-Saxon earls with his own appointees. He then limited the power of most earls giving them control of counties, castles or other territories. A few were given more power. These were titled Earl palatine.
