The relationship between Denmark and Sweden during the Kalmar Union (1397-1523) was tricky and full of problems. This made it hard for both countries to work together.

1. Power Struggles:

   • Denmark was often led by a strong king who wanted to take charge of the union. This made Swedish people feel left out and resentful because they thought their needs didn't matter.

2. Cultural and Economic Differences:

   • Denmark and Sweden had very different cultures and ways of making money. Denmark focused on building a strong navy, while Sweden cared more about farming. This difference caused more arguments between the two countries.

3. Political Conflicts:

   • There were many fights and rebellions in Sweden, like the Engelbrekt rebellion in the 1430s. These struggles showed that the Swedish people wanted more freedom and weren’t happy with Danish control. The leaders of the union often messed up and didn’t really listen to the complaints from people in Sweden.

4. Lack of Teamwork:

   • It was hard to solve problems because there were no good ways for the two countries to communicate and work together. Without a shared plan for how to run the union, the gap between them just got bigger.

Possible Solutions:

• To fix these issues, it would help to talk openly and listen to each other. Being willing to compromise and respecting each other’s cultures could lead to better teamwork. If both countries work together, they might turn their tough relationship into a fairer partnership.
