Riddarfjärden
Riddarfjärden (, "The Knight Firth") is the easternmost bay of Lake Mälaren in central Stockholm. Stockholm was founded in 1252 on an island in the stream where Lake Mälaren (from the west) drains into the Baltic Sea (to the east); today the island is called Stadsholmen and constitutes Stockholm's Old Town.
Conquest of Stockholm
The Conquest of Stockholm () was a battle in the Swedish War of Liberation that took place in Stockholm, Sweden on 17 June 1523. The Swedish forces had for a long time laid siege to Stockholm, which was the last Danish stronghold in Sweden. The city waited for reinforcement from Denmark, but none came. It was clear that negotiations must begin.
