Military plans and activities King of Władysław IV Waza (1595-1648), son of Zygmunt III Waza (1566-1632), contributed to the rapid development of cartography, particularly for military purposes. The King, appointed to the Russian throne in 1610, organised two campaigns to Moscow, in 1612 and 1617 in order to take over the rule. Both these efforts failed, but subsequent war with Moscow, in the years 1632 – 1634, ended with Polish victory. In the result of Polanów peace, Moscow gave up Livonia and most of the territories (districts of Smoleńisk, Czernichów and Siewierz) listed in the Dywilino armistice.
