Giżycko gJi'życko (former Lec or Łuczany; ; Leičių pilis) is a town in northeastern Poland with 28,597 inhabitants as of December 2021. It is situated between Lake Kisajno and Lake Niegocin in the region of Masuria, and has been within the Warmian-Masurian Voivodeship since 1999, having previously been in the Suwałki Voivodeship (1975–1998). It is the seat of Giżycko County. Giżycko is a popular summer tourist destination due to its location within the Masurian Lake District and possesses numerous historical monuments, including a 14th-century Teutonic castle. The first known settlements in the area of today's Giżycko were recorded in Roman times by Tacitus in his Germania and are connected to Amber Road in vicinity of which Giżycko was located. A defensive settlement of the Baltic Prussians was known to exist in the area, and in IX was recorded as being ruled by king known as Izegup or Jesegup. After his failed attempt in 997 AD Bolesław I the Brave sent another expedition in 1008 to conquer/Christianize the Old Prussians. Just like St. Adalbert the missionary Bruno of Querfurt was killed by Sudovians near Lake Niegocin in 1009, and a memorial the Bruno – cross was erected near in 1910. The Teutonic Knights built a castle in Prussia named Lötzen (Łuczany in Polish, later also Lec) in 1340, located at the isthmus between two lakes in today's Masuria. Lötzen was administered within the Komturei of Balga. Since the Late Middle Ages, it was mainly populated by Poles from nearby Mazovia, known as Masurians. In 1454, Polish King Casimir IV Jagiellon incorporated the region to the Kingdom of Poland upon the request of the Prussian Confederation, and after the subsequent outbreak of the Thirteen Years’ War in 1454, Łuczany sided with Poland. The settlement was captured by the Teutonic Knights in 1455, but the Poles recaptured it the next year. After the peace treaty signed in Toruń in 1466 it became part of Poland as a fief held by the Teutonic Order, until the dissolution of the Teutonic state in 1525.
