Cnut's reign was marked by several notable events and issues. One of the main issues he faced was consolidating his power and establishing himself as the undisputed king of England. He was able to achieve this through a combination of military force and political maneuvering, and by building alliances with key members of the English nobility.

Another significant event of his reign was his successful defense of his kingdom against invasions by rival claimants to the throne, including the sons of Edmund Ironside, who had briefly held the crown before Cnut's arrival.

Cnut was known for his efforts to establish a strong central government in England, and he took steps to increase the power of the monarchy, including increasing the size of his personal household and creating a more professional and centralized system of government. He also attempted to establish a more efficient system of taxation and land management.

Cnut was also well-known for his religious piety, and he made significant donations to the Church, including the rebuilding of churches and monasteries. He also encouraged the spread of Christianity in Denmark and Norway, which were under his rule.

Cnut also had a strong naval power, and he controlled a large part of the North Sea, which helped him to maintain peaceful trade and cultural exchange between the different regions of his kingdom, and also helped him to keep the Vikings raids in bay.

Overall, Cnut's reign is considered to have been relatively stable and prosperous
