Lithuania MinorLithuania Minor (Mažoji Lietuva; Kleinlitauen; Litwa Mniejsza; Ма́лая Литва́), or Prussian Lithuania (Prūsų Lietuva; Preußisch-Litauen, Litwa Pruska), is a historical ethnographic region of Prussia, where Prussian Lithuanians (or Lietuvininkai) lived, now located in Lithuania and the Kaliningrad Oblast of Russia. Lithuania Minor encompassed the northeastern part of the region and got its name from the territory's substantial Lithuanian-speaking population.
KönigsbergKönigsberg (ˈkøːnɪçsbɛʁk, King's mountain) was the historic German and Prussian name of the city that is now Kaliningrad, Russia. It was founded in 1255 on the site of the small Old Prussian settlement Twangste by the Teutonic Knights during the Baltic Crusades. It was named in honour of King Ottokar II of Bohemia, who led a campaign against the pagan Old Prussians, a Baltic tribe. A Baltic port city, it successively became the capital of the State of the Teutonic Order, the Duchy of Prussia and the provinces of East Prussia and Prussia.
First Battle of the Masurian LakesThe First Battle of the Masurian Lakes was a German offensive in the Eastern Front 2–16 September 1914, during the second month of World War I. It took place only days after the Battle of Tannenberg where the German Eighth Army encircled and destroyed the Russian Second Army. Using the rapid movements aided by the East Prussian railway network, the Eighth Army reformed in front of the spread-out Russian First Army and pushed them back across their entire front, eventually ejecting it from Germany.
MasuriaMasuria (, Masuren, Masurian: Mazurÿ) is a ethnographic and geographic region in northern and northeastern Poland, known for its 2,000 lakes. Masuria occupies much of the Masurian Lake District. Administratively, it is part of the Warmian-Masurian Voivodeship (administrative area/province). Its biggest city, often regarded as its capital, is Ełk (Elk). The region covers a territory of some 10,000 km2 which is inhabited by approximately 500,000 people.
Kaliningrad OblastKaliningrad Oblast (Калининградская область) is the westernmost federal subject of the Russian Federation. It is a semi-exclave situated on the Baltic Sea. The largest city and administrative centre of the province (oblast) is the city of Kaliningrad, formerly known as Königsberg. The port city of Baltiysk is Russia's only port on the Baltic Sea that remains ice-free in winter. Kaliningrad Oblast had a population of roughly 1 million in the Russian Census of 2021.
Duchy of PrussiaThe Duchy of Prussia (Herzogtum Preußen, Księstwo Pruskie, Prūsijos kunigaikštystė) or Ducal Prussia (Herzogliches Preußen; Prusy Książęce) was a duchy in the region of Prussia established as a result of secularization of the Monastic Prussia, the territory that remained under the control of the State of the Teutonic Order until the Protestant Reformation in 1525. The duchy became the first Protestant state when Albert, Duke of Prussia formally adopted Lutheranism in 1525.
Russian EmpireThe Russian Empire, also known as Imperial Russia, was the final period of the Russian monarchy from its proclamation in November 1721, until its dissolution in late 1917. It consisted of most of northern Eurasia. The Empire succeeded the Tsardom of Russia following the Treaty of Nystad. The rise of the Russian Empire coincided with the decline of neighbouring rival powers: the Swedish Empire, the Polish–Lithuanian Commonwealth, Qajar Iran, the Ottoman Empire, and Qing China.
