His two half-brothers, Magnus and Sigurd, were also named kings around the same time, and the three ruled Norway. By 1157, Inge's brothers were both dead, and he was the sole remaining ruler of Norway. Haakon II, an illegitimate son of Gille, then contested Inge's rule, and at the Battle of Oslo Inge was killed. According to the Heimskringla, Inge had 4,800 men.

The Siege of Hamar was a short siege that lasted for three days in late June 1537, between the forces of Catholic bishop Mogens Lauritssøn and noble Truid Ulfstand. Truid Ulfstand and his forces came down from Trondheim to arrest the bishop as a part of the Reformation in Denmark–Norway and Holstein. The bishop heard that he was going to be arrested and barricade himself and his men inside his farm at Hamar before the Protestant troops came. The Protestant troops where superior both in numbers and military tech, and when the Protestant troops arrived they laid siege to the farm. The commander of the Protestant forces had a parley with the bishop, and gave him three days to surrender or he would burn the farm. On the third day of the siege the bishop surrendered and was taken as a prisoner to Denmark, where he died in 1542.

The Battle of Kjølberg Bridge was fought 14 August 1814, during the Swedish–Norwegian war of 1814. The Swedish army had problems repairing the bridge due to constant fire from the Norwegian side of the river. It was then a small Swedish force of 75 men, consisting of jägers from the Bohuslän and Life Grenadier Regiments, passed over the river at a hidden point. Once over they waited for reinforcements but none came; but instead the order of attacking the vastly larger Norwegian force. The Colonel response to the attack order have been famous "It is unreasonable to attack with only 75 men when you face a whole regiment." "But such an order isn't given to me twice. March!" During cheers the Swedes rushed up the hill toward the mansion that was occupied with 600 men. The attack was surprising and decisive. As more Swedish troops crossed, the Norwegians quickly left the stand. This was the last battle fought during the Swedish–Norwegian War. The Convention of Moss, providing a cease fire agreement, was signed that same day.

The Battle of Largs was an indecisive engagement between the kingdoms of Norway and Scotland, on the Firth of Clyde near Largs, Scotland. The conflict formed part of the Norwegian expedition against Scotland in 1263, in which Haakon Haakonsson, King of Norway attempted to reassert Norwegian sovereignty over the western seaboard of Scotland. Since the beginning of the 12th century this region had lain within the Norwegian realm, ruled by magnates who recognised the overlordship of the kings of Norway. In the mid-13th century, two Scottish kings, Alexander II and his son Alexander III, attempted to incorporate the region into their own realm. Following failed attempts to purchase the islands from the Norwegian king, the Scots launched military operations. Haakon responded to the Scottish aggression by leading a massive fleet from Norway, which reached the Hebrides in the summer of 1263. By the end of September, Haakon's fleet occupied the Firth of Clyde, and when negotiations between the kingdoms broke down, he brought the bulk of his fleet to anchor off the Cumbraes.

The Battle of Lier was fought on 2 August 1814 between Sweden and the newly independent Norway as part of the Swedish-Norwegian War of 1814.

This was the second time during the Napoleonic Wars that a battle had taken place at Lier, the first was in 1808.

After the battle Archbishop Sigeric of Canterbury and the aldermen of the south-western provinces advised King Æthelred to buy off the Vikings rather than continue the armed struggle. The result was a payment of 10,000 Roman pounds (3,300 kg) of silver, the first example of Danegeld in England.

The Swedish forces drove the Norwegians back from their fortified positions with a disciplined bayonet-attack and dealt them considerable losses.

After a bloody battle, both Hardrada and Tostig along with most of the Norwegians were killed. Although Harold Godwinson repelled the Norwegian invaders, his army was defeated by the Normans at Hastings less than three weeks later. The battle has traditionally been presented as symbolising the end of the Viking Age, although major Scandinavian campaigns in Britain and Ireland occurred in the following decades, such as those of King Sweyn Estrithson of Denmark in 1069–1070 and King Magnus Barefoot of Norway in 1098 and 1102–1103.
