Medieval Denmark, spanning roughly from the 10th to the 16th century, was characterized by the rise of the Viking Age and the establishment of a unified kingdom. The period saw the spread of Christianity, which transformed the culture and governance of the region. Key figures like King Harald Bluetooth played a significant role in converting the Danes to Christianity and consolidating power. During this time, Denmark was involved in trade and exploration, with its people known for their seafaring skills. The Danish monarchy began to take shape, leading to the creation of laws and the development of towns. The influence of the Hanseatic League also marked this era, promoting commerce and cultural exchange.
