Unification of the Danish Kingdom

Timeline

1. c. 936–958Jelling · DenmarkTradition holds Gorm the Old as the first verifiably named king of Denmark; he established royal burial mounds and fortifications at Jelling and brought the tribes of central Jutland under hereditary rule. His little rune stone is among the oldest surviving Scandinavian inscriptions mentioning the name 'Denmark'.
2. c. 958–986Denmark and southern Norway · ScandinaviaAfter succeeding to the throne, Harald Bluetooth further conquered parts of Norway, built chains of ring fortresses (such as Trelleborg on Funen) to strengthen defenses, and promoted administrative centralization. The great Jelling stone proclaims in runes his conquest of all Denmark and Norway, marking the peak of royal integration.
3. c. 965–1000Denmark · DenmarkAfter converting to Christianity, royal power further integrated local society through church institutions, baptism, and canon law. By the late 10th century Denmark had a kingdom system resting on a hereditary monarch, central fortresses, and a church network, paving the way for the Sweyn dynasty's dominance of Scandinavia in the 11th century.
