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.
During the High Middle Ages, which began after AD 1000, the population of Europe increased greatly as technological and agricultural innovations allowed trade to flourish and the Medieval Warm Period climate change allowed crop yields to increase.he Medieval period is itself subdivided into the Early, the High, and the Late Middle Ages. Depopulation, deurbanisation, invasion, and movement of peoples, which had begun in Late Antiquity, continued in the Early Middle Ages.
