I believe "post conquestum" was also applied to Edward V.; but the records and deeds of his short reign are necessarily but few.
I conjecture that the use of the term "post conquestum" thus originated.
As we had Kings of England of the name of Edward before the Conquest, Edward the First was distinguished from these monarchs by being styled "King Edward, the son of King Henry" (his father was called "King Henry, the son of King John"). In like manner, Edward II. was distinguished from his father by being called "King Edward, the son of King Edward;" but Edward III. could not thus be distinguished from his father; he was therefore called King Edward III.; but, as there were Kings Edward before the Conquest, the third was qualified by the addition of the phrase in question, "post conquestum." To Richard II. generally, and to his successors up to Henry VIII. either generally or occasionally, the same phrase, "post conquestum," was also applied; but, if we except Edward IV. and V., this phrase was not at all required, or applicable in their cases, inasmuch as no King of England before the Conquest was named either Richard or Henry.
