The Russo-Swedish War of 1741â€“1743, known as the Hats' Russian War in Sweden and the Lesser Wrath in Finland, was instigated by the Hats, a Swedish political party which aspired to regain the territories lost to Russia during the Great Northern War, and by French diplomacy, which sought to divert Russia's attention from supporting its long-standing ally, Austria, in the War of the Austrian Succession.
The Russo-Swedish War of 1788â€“90, known as Gustav III's Russian War in Sweden and as Catherine II's Swedish War in Russia, was fought between Sweden and Russia from June 1788 to August 1790.
The Russo-Swedish War of 1495â€“1497 was a result of an alliance between Ivan III of Russia and Hans of Denmark, who was waging war against the Sture family of Sweden in the hope of regaining the Swedish throne. It is believed that Hans promised to concede some stretches of Finnish lands to the Russian monarch, although he did not bother to honour the agreement after he had been crowned King of Sweden at the close of the war.
The Russo-Swedish War of 1554â€“1557, considered a prelude to the Livonian War of 1558â€“1583, arose out of border skirmishes. Furthermore, Gustav I Vasa of Sweden felt he had been slighted by Ivan IV of Russia, because the latter made the king's ambassadors confer with a governor of Novgorod rather than receive them in the Moscow Kremlin as could have been expected between equals. The tsar responded to Gustav's remonstrances: Ask your merchants and they will tell you that Novgorod's suburbs are larger than your Stockholm and that Novgorod's governors are descended from sovereign rulers of great empires, whereas your parents sold oxen at a market several decades ago.
The Russo-Swedish War of 1590â€“1595 was instigated by Boris Godunov in the hope of recovering territory along the Gulf of Finland lost to Sweden during the previous Livonian War.
