The Siege of Pskov took place during the final stage of a war that fought for control of what area?
Livonian War The Livonian War (1558–1583) was fought for control of Old Livonia (in the territory of present-day Estonia and Latvia), when the Tsardom of Russia faced a varying coalition of Denmark–Norway, the Kingdom of Sweden, and the Union (later Commonwealth) of the Grand Duchy of Lithuania and the Kingdom of Poland.
Siege of Belaya The Siege of Belaya was the final military episode of the Smolensk War. The heroic defense of the fortress by its small Russian garrison against a large Polish-Lithuanian army of King Władysław IV Vasa thwarted the king's plan to march against Moscow and made him sign the Treaty of Polyanovka in which he relinquished his claims to the Russian throne.
