This important year (550) is what we consider to be the beginning of âthe Early Middle Agesâ and lasted until 1000. When you think about it, the Middle Ages were a very, very long period of time, and so itâs easier to break up these periods of time into the Early, High, and Late Middle Ages. But for now, letâs focus on what was happening during the Early Middle Ages.
Dates for the medieval period are usually given as 476 to 1453 AD, or something like that. The middle ages began with the decline of the West Roman Empire, which took a long â¦ time, and so really has no fixed date.Similarly, they ended with a long series of events that are more emblematic than anything else.nd the middle ages are the time in which the first seventy universities were founded. Nor were the middle ages a time without science. The list of medieval inventions is long and impressive. They include such things as the invention of the chimney, soap, and ultimately, the printing press.
