One major characteristic of this era in the Eastern Baltic is the strife between the two major political parties, the Hats, representing the upper classes, and the Caps, representing the lower classes.

These political parties, however, prove no more competent in the realm of foreign affairs than the kings.

In 1741 the Hats lead Sweden into a war with Russia in order to try to undo the result of the Peace of Uusikaupunki.

Russian forces thereupon invade Finland and begin, virtually without a fight, a short-lived occupation known as the Lesser Wrath.

In accordance with the Peace of Turku signed in 1743, Russia once again evacuates Finland, but takes another slice of Finnish territory along the southeastern frontier.
