Treaty of Åbo

The Treaty of Åbo or Treaty of Turku is a Peace Treaty between Imperial Russia and Sweden after the Hats' Russian War 1741–43.

Sweden ceded to Russia the areas east of the Kymi river and around Savonlinna, thus all the southern Karelia now belonged to Russia.

The Russian ruler guaranteed religion, properties, laws and privileges of the inhabitants of ceded territories. For example, these territories had just a few years earlier adopted (together with the rest of then-Sweden) the 1734 General Law of Sweden.
