In the thirteenth century, the king ruling Sweden was King Knut Eriksson also called Canute. During Canute's reign, there was a boy named Sverker, whose mother was Danish and father was Swedish. During King Knut's reign, the boy went to live in Denmark where the Danish king of the time started using him to get power over Sweden and destabilize it. In 1196 at the time when Canute's sons were to inherit the royal kingship, they were still too young to do so. Sverker was then chosen to be the next King of Sweden in an uncontested election that was organized by Jarl Birger Brosa. Sverker later married the jarl's daughter. Some people concerned with the leadership of Sweden were not in agreement with this appointment. Since the opposition's numbers were few, King Sverker and his allies did not believe this would impact his hold on power.

In 1203, Canute's four sons began to claim the throne, a measure that led King Sverker to exile them to Norway. When Birger Borsa died King Sverker's rulle was under threat. Canute's sons, after two years, returned to Sweden with troops to overthrow Sverker's leadership. The Norwegian party of Birkebeiner aided them. Sverker succeeded in winning the first of the battle which resulted in the death of three of Canute's sons. In 1208, the remaining son with support of a Norwegian aliance went back to Sweden for war to oust King Sverker from the throne. This time Sverker was defeated and went to exile in Denmark. Erik Knutsson (Canute's remaining son) took over as the next king. Sverker and his allies attempted to get the crown back peacefully but did not succeed. This gave birth to another war that was referred to as the Battle of Gestilren in which King Sverker was killed. Since King Sverker's crown was given to him courtesy of the Danish royals, his defeat and death led to the reduction in influence of Denmark over Sweden thereby making Sweden's claim of its superiority over Denmark both in economics and in war. The defeat and death of King Sverker also weakened the reign of Danish King, Valdemar the Victorious and thus prepared the way for his retaliation. In the retaliation. The battle also attracted a war between Denmark and Norway where some Danes were killed including Valdemar's tax collector. King Sverker's church-friendly policies were overturned with his defeat leading to the Swedish Church and its archbishops being denied ecclesiastical privileges.

All the parties that took part in the war were to benefit from it mutually. This meant that after Erik became the king of Sweden with the help of the Norwegians the relationship enhanced both the social and economic trade between both countries. During the battle, cities like Vastergotland and Gastre were born and/or given the publicity that raised their status from mere small towns to cities. The battle also gave rise to other small cities where soldiers involved in the battle camped. These cities are now strong attractions to tourists today and earn the Swedish government a lot of revenue hence positively contributing to economic development. They also form a strong source of historical information to Swedish historians and other historians all over the world who are interested in studying the history of Scandinavia.
