Teutonic Order in the context of Hospital

Nicolaus Copernicus (19 February 1473 – 24 May 1543) was a Renaissance polymath who formulated a model of the universe that placed the Sun rather than Earth at its center. The publication of Copernicus's model in his book De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres), just before his death in 1543, was a major event in the history of science, triggering the Copernican Revolution and making a pioneering contribution to the Scientific Revolution. Though a similar heliocentric model had been developed eighteen centuries earlier by Aristarchus of Samos, an ancient Greek astronomer, Copernicus likely arrived at his model independently.

Copernicus was born and died in Royal Prussia, a semiautonomous and multilingual region created within the Crown of the Kingdom of Poland from lands regained from the Teutonic Order after the Thirteen Years' War.

A military order (Latin: Ordo militaris) is a Latin Catholic religious order of knights. The original military orders were the Knights Templar, the Knights Hospitaller, the Order of the Holy Sepulchre, the Order of Saint James, the Order of Calatrava, and the Teutonic Knights. They arose in the Middle Ages in association with the Crusades – the Crusader states (mainly the Kingdom of Jerusalem in the Holy Land), the Baltics, and the Iberian peninsula; their members being initially dedicated to the protection of Christian pilgrims, and eventually to the defence of the Crusader states and the conquest of non-Christian or even non-Catholic lands. They are the predecessors of chivalric orders.

Most members of military orders were laymen who took religious vows, such as of poverty, chastity, and obedience, according to monastic ideals. The orders owned houses called commanderies all across Europe and had a hierarchical structure of leadership with the grand master at the top.

The Fifth Crusade (September 1217 – August 29, 1221) was a campaign in a series of Crusades by Western Europeans to reacquire Jerusalem and the rest of the Holy Land by first conquering Egypt, ruled by the powerful Ayyubid sultanate, led by al-Adil, brother of Saladin.

After the failure of the Fourth Crusade, Innocent III again called for a crusade, and began organizing Crusading armies led by Andrew II of Hungary and Leopold VI of Austria, soon to be joined by John of Brienne, titular King of Jerusalem. An initial campaign in late 1217 in Syria was inconclusive, and Andrew departed. A German army led by cleric Oliver of Paderborn, and a mixed army of Dutch, Flemish and Frisian soldiers led by William I of Holland, then joined the Crusade in Acre, with a goal of first conquering Egypt, viewed as the key to Jerusalem. There, cardinal Pelagius Galvani arrived as papal legate and de facto leader of the Crusade, supported by John of Brienne and the masters of the Templars, Hospitallers and Teutonic Knights. Holy Roman Emperor Frederick II, who had taken the cross in 1215, did not participate as promised.

The Battle of Grunwald is a painting by Jan Matejko depicting the Battle of Grunwald and the victory of the allied Crown of the Kingdom of Poland and Grand Duchy of Lithuania over the Teutonic Order in 1410. The canvas dates to 1878 and is one of the most heroic representations of the history of Poland and Lithuania. It is displayed in the National Museum in Warsaw.

The painting's main focus is the death scene of the Grand Master of the Teutonic Order, Ulrich von Jungingen; another central figure is the Lithuanian grand duke Vytautas the Great, dressed in red with a raised sword. The painting has been both hailed and criticized for its complexity. It is one of Matejko's most recognizable works, and has likely contributed to the popular image of the battle of Grunwald, and its enduring fame in Polish and Lithuanian consciousness.

Prussia (/ˈprʌʃə/; German: Preußen [ˈpʁɔʏsn̩] ; Old Prussian: Prūsija) was a German state centred on the North European Plain that originated from the 1525 secularization act of the Prussian part of the State of the Teutonic Order. For centuries, the House of Hohenzollern ruled Prussia, expanding its size with the Prussian Army. Prussia, with its capital at Königsberg and then, when it became the Kingdom of Prussia in 1701, Berlin, decisively shaped the history of Germany. Prussia formed the German Empire when it united the German states in 1871. It was de facto dissolved by an emergency decree transferring powers of the Prussian government to German Chancellor Franz von Papen in 1932 and de jure by an Allied decree in 1947.

The name Prussia derives from the Old Prussians who were conquered by the Teutonic Knights – an organized Catholic medieval military order of German crusaders – in the 13th century. In 1308, the Teutonic Knights conquered the region of Pomerelia with Danzig. Their monastic state was mostly Germanised through immigration from central and western Germany, and, in the south, it was Polonised by settlers from Masovia. The imposed Second Peace of Thorn (1466) split Prussia into the western Royal Prussia, a province of Poland, and the eastern Duchy of Prussia, a feudal fief of the Crown of Poland until 1657. After 1525, the Teutonic Order relocated their headquarters to Mergentheim, but managed to keep land in Livonia until 1561. The union of Brandenburg and the Duchy of Prussia in 1618 led to the proclamation of the Kingdom of Prussia in 1701.

The Iron Cross (German: Eisernes Kreuz, listen, abbreviated EK) was a military decoration in the Kingdom of Prussia, the German Empire (1871–1918), and Nazi Germany (1933–1945). The design, a black cross pattée with a white or silver outline, was derived from the insignia of the medieval Teutonic Order and borne by its knights from the 13th century. As well as being a military medal, it has also been used as an emblem by the Prussian Army, the Imperial German Army, and the Reichswehr of the Weimar Republic, while the Balkenkreuz (bar cross) variant was used by the Wehrmacht. The Iron Cross is now the emblem of the Bundeswehr, the modern German armed forces.

King Frederick William III of Prussia established the Iron Cross award on 17 March 1813 during the Napoleonic Wars (EK 1813). The award was backdated to the birthday (10 March) of his late wife, Queen Louise, who was the first person to receive it (posthumously). The Iron Cross was also awarded during the Franco-Prussian War (EK 1870), World War I (EK 1914), and World War II (EK 1939). During World War II, the Nazi regime made their own version by superimposing a swastika on the medal. The Iron Cross was usually a military decoration only, though some were awarded to civilians for performing military roles, including Hanna Reitsch and Melitta Schenk Gräfin von Stauffenberg for being civilian test pilots during World War II.

Gdańsk (Kashubian: Gduńsk; German: Danzig) is a city on the Baltic coast of northern Poland, and the capital of the Pomeranian Voivodeship. With a population of 486,492, it is Poland's sixth-largest city and its major seaport. Gdańsk lies at the mouth of the Motława River and is situated at the southern edge of Gdańsk Bay, close to the city of Gdynia and the resort town of Sopot; these form a metropolitan area called the Tricity (Trójmiasto), with a population of approximately 1.5 million.

Gdańsk was first mentioned in 997 as part of the early Polish state, and thereafter grew into a trading town under the Piast and Samboride dynasties. Shifting between Polish and Teutonic control during the Middle Ages, it subsequently joined the Hanseatic League and, with considerable autonomy, served as Poland's principal seaport and largest city until the early 18th century. With the Partitions of Poland, the city was annexed by Prussia in 1793, and was integrated into the German Empire in 1871. It was a free city from 1807 to 1814 and from 1920 to 1939. On 1 September 1939, it was the site of a military clash at Westerplatte, one of the first events of World War II. The contemporary city was shaped by extensive border changes, expulsions and resettlement after 1945. In the 1980s, Gdańsk was the birthplace of the Solidarity trade union and movement, which helped precipitate the collapse of communism in Europe.

The Thirteen Years' War (Polish: wojna trzynastoletnia; German: Dreizehnjähriger Krieg), also called the War of the Cities, was a conflict fought in 1454–1466 between the Crown of the Kingdom of Poland and the Teutonic Order.

After the enormous defeat suffered by the German Order at the hand of Poland-Lithuania in 1410 and the ensuing political, military and economic problems, the state was rife with internal conflict between the ruling Order and the native Prussian warlords, who shared concerns with assimilated Prussian and German townsfolk. Eventually this tension led to an uprising by the Prussian Confederation representing the local Prussian nobility and cities, who sought the protection of the Polish King Casimir IV Jagiellon. This essentially amounted to a switching of sides which the German Order immediately took as a mortal threat, and a war broke out between Poland and the Teutons.

Ancient Estonia refers to a period covering History of Estonia from the middle of the 8th millennium BC until the conquest and subjugation of the local Finnic tribes in the first quarter of the 13th century during the Teutonic and Danish Northern Crusades.

The State of the Teutonic Order (German: Staat des Deutschen Ordens, pronounced [ˈʃtaːt dɛs ˌdɔʏtʃn̩ ˈʔɔʁdn̩s] ) was a theocratic state located along the southeastern shore of the Baltic Sea in northern Europe. It was formed by the knights of the Teutonic Order during the early 13th century Northern Crusades in the region of Prussia. In 1237, the Livonian Brothers of the Sword merged with the Teutonic Order of Prussia and became known as its branch – the Livonian Order (while their state, Terra Mariana, covering present-day Estonia, Latvia, and a small part of Russia, became part of the State of the Teutonic Order). At its greatest territorial extent during the early 15th century, the State encompassed Chełmno Land, Courland, Gotland, Livonia, Estonia, Neumark, Pomerelia (Gdańsk Pomerania), Prussia and Samogitia.

Following the battles of Grunwald in 1410 and Wilkomierz in 1435, the State fell into decline. After losing extensive territories in the imposed Peace of Thorn in 1466, the extant territory of its Prussian branch became known as Monastic Prussia (Polish: Prusy zakonne) or Teutonic Prussia (Polish: Prusy krzyżackie). It existed until 1525 as a fiefdom of the Polish Crown. The Livonian branch joined the Livonian Confederation and continued to exist as part of it until 1561.

The Duchy of Estonia (Estonian: Eestimaa hertsogkond, Danish: Hertugdømmet Estland Latin: Ducatus Estoniae), also known as Danish Estonia, was a direct dominion (Latin: dominium directum) of the King of Denmark from 1219 until 1346 when it was sold to the Teutonic Order and became part of the Ordensstaat.

Denmark rose as a great military and mercantile power in the 12th century. It had an interest in ending the frequent Estonian attacks that threatened its Baltic trade. Danish fleets attacked Estonia in 1170, 1194, and 1197. In 1206, King Valdemar II and archbishop Andreas Sunonis led a raid on Ösel island (Saaremaa). The Kings of Denmark claimed Estonia, and this was recognised by Pope Honorius III. In 1219, the fleet of Valdemar II landed in the harbor of Lindanise (Tallinn) and defeated the local Estonians in the Battle of Lindanise. This brought northern Estonia under Danish rule until the Estonian uprising in 1343, after which the territories were taken over by the Teutonic Order. They were sold by Denmark in 1346.

The Lithuanian Crusade was a series of campaigns by the Teutonic Order and the Livonian Order under the pretext of forcibly Christianizing the pagan Grand Duchy of Lithuania. The Livonian Order occupied Riga in 1202 and in the 1230s they settled in Chełmno Land, a fief of Poland. They first conquered other neighboring Baltic tribes— proto-Latvians (Curonians, Semigallians, Latgalians, Selonians) and Old Prussians—in the Livonian Crusade and Prussian Crusade.

The first raid against the Lithuanians and Samogitians was in 1208. From then on, the orders played a key role in Lithuanian politics, but they were not a direct threat until the 1280s. By that time, the Grand Duchy of Lithuania was already a centralized state and could mount defenses. For the next century, the order organized annual colonialist reise (raids) into Samogitian and Lithuanian lands, without great success but at immense human cost. Border regions in Samogitia and Suvalkija became sparsely inhabited wilderness due to ethnic cleansing, although the order gained very little territory. The resulting wars between the Teutonic Order and Lithuania were one of the longest conflicts in the history of Europe.

Siemowit IV (Ziemowit IV), also known as Siemowit IV the Younger (pl: Siemowit IV Młodszy; ca. 1353/1356 – 21 January 1426), was a Polish prince, member of the Masovian branch of the House of Piast and from 1373 or 1374 Duke of Rawa, and after the division of the paternal inheritance between him and his brother in 1381, ruler over Rawa, Płock, Sochaczew, Gostynin, Płońsk and Wizna, after 1386 hereditary Polish vassal, after 1388 ruler over Belz. During 1382–1401 he lost Wizna and during 1384–1399 and 1407–1411 he lost Zawkrze, during 1384–1399 he lost Płońsk, which was taken by the Teutonic Order.

He was the second son of Siemowit III, Duke of Masovia and his first wife Euphemia, daughter of Nicholas II of Opava.

Kreva Castle (Belarusian: Крэўскі замак, Lithuanian: Krėvos pilis, Polish: zamek w Krewie) is the ruins of a major fortified residence of the rulers of Grand Duchy of Lithuania Gediminas and Algirdas in the village of Kreva, Belarus. The village lies 220 metres (720 ft) above sea level.

During the Lithuanian Civil War (1381–1384), Jogaila, Algirdas's son, arrested and imprisoned his uncle Kęstutis and cousin Vytautas in the Kreva Castle in 1382. One week later, Kęstutis was found dead. Whether he died of natural causes or was murdered is still a matter of debate. His son, Vytautas, however, escaped from Kreva and fled to the Teutonic Order.

The Battle of Grunwald was fought on 15 July 1410 during the Polish–Lithuanian–Teutonic War. The alliance of the Crown of the Kingdom of Poland and the Grand Duchy of Lithuania, led respectively by King Władysław II Jagiełło (Jogaila), and Grand Duke Vytautas, decisively defeated the German Teutonic Order, led by Grand Master Ulrich von Jungingen. Most of the Teutonic Order's leadership was killed or taken prisoner.

Although defeated, the Teutonic Order withstood the subsequent siege of the Malbork Castle and suffered minimal territorial losses at the Peace of Thorn (1411), with other territorial disputes continuing until the Treaty of Melno in 1422. The order, however, never recovered their former power, and the financial burden of war reparations caused internal conflicts and an economic downturn in the lands controlled by them. The battle shifted the balance of power in Central and Eastern Europe and marked the rise of the Polish–Lithuanian union as the dominant regional political and military force.
