Northern Seven Years' War (jan 1, 1563 – jan 1, 1570)

Description:

The Swedes aimed at spreading their empire throughout the Baltic Sea, which lead to spreading into modern-day Estonia. But of course, Denmark had its sight on the same exact area. This resulted in another small war with Denmark called the Northern Seven Years' War. The war resulted in nothing but even higher tensions between Denmark and Sweden, with no side actually gaining any extra territory. Although not much was accomplished, this was one of the many conflicts that lead to even high tensions between these two ambitious states.
