Final answer:
The medieval world was characterized by feudalism, manorialism, medieval Christianity, and Viking invasions, with the feudal system arising after the collapse of the Roman Empire.
Step-by-step explanation:
The medieval world featured several distinct characteristics aside from feudalism. One significant aspect was the Manorialism, which was the organization of peasants into villages that owed rent and labor services to nobles. Another fundamental part was the role of the Church, which was both a spiritual and a political entity during this time, leading to what is called Medieval Christianity. Additionally, the period was marked by frequent invasions and conflicts, such as those by the Vikings, who were among the notable invaders of Europe.
