In the parliament, the representatives were divided into two groups. One of them eagerly wanted to bring Sweden back to great power, even if it meant a new war. This group was called hatutu after their triangular hats. Another group wanted a calmer policy. They were called myssyt after their own headdress mold. Both groups tried to get a majority of the representatives of each statute on their side.

Hatut and Myssyt disagreed on almost everything related to the care of the kingdom. This is well illustrated by the fact that hatut mocked myssyt as yömyssyt (night caps), as these supposedly did not understand anything about state care, i.e., wore a hat with their eyes in their sleep when important decisions were made.

The hatut came to power in 1741 started a war against Russia to restore the Swedish superpower. Sweden did not succeed, and Russia occupied Finland for two years. This war is called the war of hats.
