The Russo-Swedish War of 1741–1743, known as the Hats' Russian War in Sweden and the Hats' War in Finland, which results in the Lesser Wrath, or the occupation of Finland, is instigated by the Hats, a Swedish political party that aspires to regain the territories lost to Russia during the Great Northern War, and by French diplomacy, which seeks to divert Russia's attention from supporting its long-standing ally, Austria, in the War of the Austrian Succession.
