When did feudalism start and end?

Probably the most commonly used dates for the Middle Ages are 476 AD to 1453 AD. Other dates are given for both the beginning and the end by different historians. Some historians simply give 5th century to 15th century.

Some historians regard the Middle Ages as only the second half of this period, calling the first half the Dark Ages. These people use about the same end date, but most commonly use 1000 or 1066 as the start dates.
