Malbork Castle
–
The Castle of the Teutonic Order in Malbork, located in the Polish town of Malbork, is the largest castle in the world measured by land area. It was originally built by the Teutonic Knights, a German Roman Catholic religious order of crusaders, the town which grew around it was also named Marienburg. In 1466, both castle and town became part of Royal Prussia, a province of Poland, heavily damaged after World War II, the castle was renovated under the auspices of modern-day Poland in the second half of the 20th century and most recently in 2016. Nowadays, the castle hosts exhibitions and serves as a museum, the castle is a classic example of a medieval fortress and, on its completion in 1406, was the worlds largest brick castle. UNESCO designated the Castle of the Teutonic Order in Malbork and the Malbork Castle Museum a World Heritage Site in December 1997 and it is one of two World Heritage Sites in the region with origins in the Teutonic Order. The other is the Medieval Town of Toruń, founded in 1231 as the site of the castle Thorn, Malbork Castle is also one of Polands official national Historic Monuments, as designated September 16,1994. Its listing is maintained by the National Heritage Board of Poland, the castle was built by the Teutonic Order after the conquest of Old Prussia. Its main purpose was to strengthen their own control of the following the Orders 1274 suppression of the Great Prussian Uprising of the Baltic tribes. The work lasted until around 1300, under the auspices of Commander Heinrich von Wilnowe, the castle is located on the southeastern bank of the river Nogat. It was named Marienburg after Mary, patron saint of the religious Order, the Order had been created in Acre. When this last stronghold of the Crusades fell to Muslim Arabs, Malbork became more important in the aftermath of the Teutonic Knights conquest of Gdańsk and Pomerania in 1308. The Orders administrative centre was moved to Marienburg from Elbing, the Grand Master of the Teutonic Knights, Siegfried von Feuchtwangen, who arrived in Marienburg from Venice, undertook the next phase of the fortress construction. In 1309, in the wake of the persecution of the Knights Templar. He chose the site of Marienburg conveniently located on the Nogat in the Vistula Delta, as with most cities of the time, the new centre was dependent on water for transportation. The castle was expanded several times to house the number of Knights. Soon, it became the largest fortified Gothic building in Europe, the castle has several subdivisions and numerous layers of defensive walls. It consists of three separate castles - the High, Middle and Lower Castles, separated by dry moats. The castle once housed approximately 3,000 brothers in arms, the outermost castle walls enclose 21 ha, four times the enclosed area of Windsor Castle

German Empire
–
The German Empire was the historical German nation state that existed from the unification of Germany in 1871 to the abdication of Kaiser Wilhelm II in 1918, when Germany became a federal republic. The German Empire consisted of 26 constituent territories, with most being ruled by royal families and this included four kingdoms, six grand duchies, five duchies, seven principalities, three free Hanseatic cities, and one imperial territory. Although Prussia became one of kingdoms in the new realm, it contained most of its population and territory. Its influence also helped define modern German culture, after 1850, the states of Germany had rapidly become industrialized, with particular strengths in coal, iron, chemicals, and railways. In 1871, it had a population of 41 million people, and by 1913, a heavily rural collection of states in 1815, now united Germany became predominantly urban. During its 47 years of existence, the German Empire operated as an industrial, technological, Germany became a great power, boasting a rapidly growing rail network, the worlds strongest army, and a fast-growing industrial base. In less than a decade, its navy became second only to Britains Royal Navy, after the removal of Chancellor Otto von Bismarck by Wilhelm II, the Empire embarked on a bellicose new course that ultimately led to World War I. When the great crisis of 1914 arrived, the German Empire had two allies, Italy and the Austro-Hungarian Empire, Italy, however, left the once the First World War started in August 1914. In the First World War, German plans to capture Paris quickly in autumn 1914 failed, the Allied naval blockade caused severe shortages of food. Germany was repeatedly forced to send troops to bolster Austria and Turkey on other fronts, however, Germany had great success on the Eastern Front, it occupied large Eastern territories following the Treaty of Brest-Litovsk. German declaration of unrestricted submarine warfare in early 1917 was designed to strangle the British, it failed, but the declaration—along with the Zimmermann Telegram—did bring the United States into the war. Meanwhile, German civilians and soldiers had become war-weary and radicalised by the Russian Revolution and this failed, and by October the armies were in retreat, Austria-Hungary and the Ottoman Empire had collapsed, Bulgaria had surrendered and the German people had lost faith in their political system. The Empire collapsed in the November 1918 Revolution as the Emperor and all the ruling monarchs abdicated, and a republic took over. The German Confederation had been created by an act of the Congress of Vienna on 8 June 1815 as a result of the Napoleonic Wars, German nationalism rapidly shifted from its liberal and democratic character in 1848, called Pan-Germanism, to Prussian prime minister Otto von Bismarcks pragmatic Realpolitik. He envisioned a conservative, Prussian-dominated Germany, the war resulted in the Confederation being partially replaced by a North German Confederation in 1867, comprising the 22 states north of the Main. The new constitution and the title Emperor came into effect on 1 January 1871, during the Siege of Paris on 18 January 1871, William accepted to be proclaimed Emperor in the Hall of Mirrors at the Palace of Versailles. The second German Constitution was adopted by the Reichstag on 14 April 1871 and proclaimed by the Emperor on 16 April, the political system remained the same. The empire had a parliament called the Reichstag, which was elected by universal male suffrage, however, the original constituencies drawn in 1871 were never redrawn to reflect the growth of urban areas

Castle
–
A castle is a type of fortified structure built in Europe and the Middle East during the Middle Ages by European nobility. Scholars debate the scope of the castle, but usually consider it to be the private fortified residence of a lord or noble. Usage of the term has varied over time and has applied to structures as diverse as hill forts. Over the approximately 900 years that castles were built, they took on a great many forms with different features, although some, such as curtain walls. A European innovation, castles originated in the 9th and 10th centuries, after the fall of the Carolingian Empire resulted in its territory being divided among individual lords and princes. Although their military origins are often emphasised in castle studies, the structures served as centres of administration. Many castles were built from earth and timber, but had their defences replaced later by stone. Early castles often exploited natural defences, lacking features such as towers and arrowslits, in the late 12th and early 13th centuries, a scientific approach to castle defence emerged. This led to the proliferation of towers, with an emphasis on flanking fire, many new castles were polygonal or relied on concentric defence – several stages of defence within each other that could all function at the same time to maximise the castles firepower. These changes in defence have been attributed to a mixture of castle technology from the Crusades, such as concentric fortification, not all the elements of castle architecture were military in nature, so that devices such as moats evolved from their original purpose of defence into symbols of power. Some grand castles had long winding approaches intended to impress and dominate their landscape, while castles continued to be built well into the 16th century, new techniques to deal with improved cannon fire made them uncomfortable and undesirable places to live. As a result, true castles went into decline and were replaced by artillery forts with no role in civil administration, and country houses that were indefensible. From the 18th century onwards, there was a renewed interest in castles with the construction of castles, part of a romantic revival of Gothic architecture. The word castle is derived from the Latin word castellum, which is a diminutive of the word castrum, meaning fortified place. The Old English castel, Old French castel or chastel, French château, Spanish castillo, Italian castello, the word castle was introduced into English shortly before the Norman Conquest to denote this type of building, which was then new to England. In its simplest terms, the definition of a castle accepted amongst academics is a fortified residence. Feudalism was the link between a lord and his vassal where, in return for service and the expectation of loyalty. Castles served a range of purposes, the most important of which were military, administrative, as well as defensive structures, castles were also offensive tools which could be used as a base of operations in enemy territory

Fortification
–
Fortifications are military constructions or buildings designed for the defense of territories in warfare, and also used to solidify rule in a region during peace time. Humans have constructed defensive works for many thousands of years, in a variety of increasingly complex designs, the term is derived from the Latin fortis and facere. From very early history to modern times, walls have been a necessity for cities to survive in a changing world of invasion. Some settlements in the Indus Valley Civilization were the first small cities to be fortified, in ancient Greece, large stone walls had been built in Mycenaean Greece, such as the ancient site of Mycenae. A Greek Phrourion was a collection of buildings used as a military garrison. These construction mainly served the purpose of a tower, to guard certain roads, passes. Though smaller than a fortress, they acted as a border guard rather than a real strongpoint to watch. The art of setting out a camp or constructing a fortification traditionally has been called castramentation since the time of the Roman legions. Fortification is usually divided into two branches, permanent fortification and field fortification, there is also an intermediate branch known as semi-permanent fortification. Castles are fortifications which are regarded as being distinct from the fort or fortress in that they are a residence of a monarch or noble. Roman forts and hill forts were the antecedents of castles in Europe. The Early Middle Ages saw the creation of towns built around castles. Medieval-style fortifications were made obsolete by the arrival of cannons in the 14th century. Fortifications in the age of black powder evolved into much lower structures with greater use of ditches and earth ramparts that would absorb, Walls exposed to direct cannon fire were very vulnerable, so were sunk into ditches fronted by earth slopes. The arrival of explosive shells in the 19th century led to yet another stage in the evolution of fortification, steel-and-concrete fortifications were common during the 19th and early 20th centuries. However the advances in warfare since World War I have made large-scale fortifications obsolete in most situations. Demilitarized zones along borders are arguably another type of fortification, although a passive kind, many military installations are known as forts, although they are not always fortified. Larger forts may be called fortresses, smaller ones were known as fortalices

Crusades
–
The First Crusade arose after a call to arms in a 1095 sermon by Pope Urban II. Urban urged military support for the Byzantine Empire and its Emperor, Alexios I, the response to Urbans preaching by people of many different classes across Western Europe established the precedent for later Crusades. Volunteers became Crusaders by taking a vow and receiving plenary indulgences from the church. Some were hoping for apotheosis at Jerusalem, or forgiveness from God for all their sins, others participated to satisfy feudal obligations, gain glory and honour, or find opportunities for economic and political gain. Many modern Historians have polarised opinions of the Crusaders behaviour under Papal sanction, to some it was incongruous with the stated aims and implied moral authority of the papacy and the Crusades, to the extent that on occasions that the Pope excommunicated Crusaders. Crusaders often pillaged as they travelled, while their leaders retained control of captured territory rather than returning it to the Byzantines. During the Peoples Crusade thousands of Jews were murdered in what is now called the Rhineland massacres, Constantinople was sacked during the Fourth Crusade rendering the reunification of Christendom impossible. These tales consequently galvanised medieval romance, philosophy and literature, but the Crusades also reinforced the connection between Western Christendom, feudalism, and militarism. Crusade is not a term, instead the terms iter for journey or peregrinatio for pilgrimage were used. Not until the word crucesignatus for one who was signed with the cross was adopted at the close of the century was specific terminology developed. The Middle English equivalents were derived from old French, croiserie in the 13th–15th centuries, croisade appeared in English c1575, and continued to be the leading form till c1760. By convention historians adopt the term for the Christian holy wars from 1095, the Crusades in the Holy Land are traditionally counted as nine distinct campaigns, numbered from the First Crusade of 1095–99 to the Ninth Crusade of 1271/2. Usage of the term Crusade may differ depending on the author, pluralists use the term Crusade of any campaign explicitly sanctioned by the reigning Pope. This reflects the view of the Roman Catholic Church that every military campaign given Papal sanction is equally valid as a Crusade, regardless of its cause, justification, generalists see Crusades as any and all holy wars connected with the Latin Church and fought in defence of their faith. Popularists limit the Crusades to only those that were characterised by popular groundswells of religious fervour – that is, only the First Crusade, Medieval Muslim historiographers such as Ali ibn al-Athir refer to the Crusades as the Frankish Wars. The term used in modern Arabic, ḥamalāt ṣalībiyya حملات صليبية, campaigns of the cross, is a loan translation of the term Crusade as used in Western historiography. The Islamic prophet Muhammad founded Islam in the Arabian Peninsula, the resulting unified polity in the seventh and eighth centuries led to a rapid expansion of Arab power. This influence stretched from the northwest Indian subcontinent, across Central Asia, the Middle East, North Africa, southern Italy, tolerance, trade, and political relationships between the Arabs and the Christian states of Europe waxed and waned

Middle Ages
–
In the history of Europe, the Middle Ages or Medieval Period lasted from the 5th to the 15th century. It began with the fall of the Western Roman Empire and merged into the Renaissance, the Middle Ages is the middle period of the three traditional divisions of Western history, classical antiquity, the medieval period, and the modern period. The medieval period is subdivided into the Early, High. Population decline, counterurbanisation, invasion, and movement of peoples, the large-scale movements of the Migration Period, including various Germanic peoples, formed new kingdoms in what remained of the Western Roman Empire. In the seventh century, North Africa and the Middle East—once part of the Byzantine Empire—came under the rule of the Umayyad Caliphate, although there were substantial changes in society and political structures, the break with classical antiquity was not complete. The still-sizeable Byzantine Empire survived in the east and remained a major power, the empires law code, the Corpus Juris Civilis or Code of Justinian, was rediscovered in Northern Italy in 1070 and became widely admired later in the Middle Ages. In the West, most kingdoms incorporated the few extant Roman institutions, monasteries were founded as campaigns to Christianise pagan Europe continued. The Franks, under the Carolingian dynasty, briefly established the Carolingian Empire during the later 8th, the Crusades, first preached in 1095, were military attempts by Western European Christians to regain control of the Holy Land from Muslims. Kings became the heads of centralised nation states, reducing crime and violence, intellectual life was marked by scholasticism, a philosophy that emphasised joining faith to reason, and by the founding of universities. Controversy, heresy, and the Western Schism within the Catholic Church paralleled the conflict, civil strife. Cultural and technological developments transformed European society, concluding the Late Middle Ages, the Middle Ages is one of the three major periods in the most enduring scheme for analysing European history, classical civilisation, or Antiquity, the Middle Ages, and the Modern Period. Medieval writers divided history into periods such as the Six Ages or the Four Empires, when referring to their own times, they spoke of them as being modern. In the 1330s, the humanist and poet Petrarch referred to pre-Christian times as antiqua, leonardo Bruni was the first historian to use tripartite periodisation in his History of the Florentine People. Bruni and later argued that Italy had recovered since Petrarchs time. The Middle Ages first appears in Latin in 1469 as media tempestas or middle season, in early usage, there were many variants, including medium aevum, or middle age, first recorded in 1604, and media saecula, or middle ages, first recorded in 1625. The alternative term medieval derives from medium aevum, tripartite periodisation became standard after the German 17th-century historian Christoph Cellarius divided history into three periods, Ancient, Medieval, and Modern. The most commonly given starting point for the Middle Ages is 476, for Europe as a whole,1500 is often considered to be the end of the Middle Ages, but there is no universally agreed upon end date. English historians often use the Battle of Bosworth Field in 1485 to mark the end of the period

Nazi Germany
–
Nazi Germany is the common English name for the period in German history from 1933 to 1945, when Germany was governed by a dictatorship under the control of Adolf Hitler and the Nazi Party. Under Hitlers rule, Germany was transformed into a fascist state in which the Nazi Party took totalitarian control over all aspects of life. The official name of the state was Deutsches Reich from 1933 to 1943, the period is also known under the names the Third Reich and the National Socialist Period. The Nazi regime came to an end after the Allied Powers defeated Germany in May 1945, Hitler was appointed Chancellor of Germany by the President of the Weimar Republic Paul von Hindenburg on 30 January 1933. The Nazi Party then began to eliminate all opposition and consolidate its power. Hindenburg died on 2 August 1934, and Hitler became dictator of Germany by merging the powers and offices of the Chancellery, a national referendum held 19 August 1934 confirmed Hitler as sole Führer of Germany. All power was centralised in Hitlers person, and his word became above all laws, the government was not a coordinated, co-operating body, but a collection of factions struggling for power and Hitlers favour. In the midst of the Great Depression, the Nazis restored economic stability and ended mass unemployment using heavy military spending, extensive public works were undertaken, including the construction of Autobahnen. The return to economic stability boosted the regimes popularity, racism, especially antisemitism, was a central feature of the regime. The Germanic peoples were considered by the Nazis to be the purest branch of the Aryan race, millions of Jews and other peoples deemed undesirable by the state were murdered in the Holocaust. Opposition to Hitlers rule was ruthlessly suppressed, members of the liberal, socialist, and communist opposition were killed, imprisoned, or exiled. The Christian churches were also oppressed, with many leaders imprisoned, education focused on racial biology, population policy, and fitness for military service. Career and educational opportunities for women were curtailed, recreation and tourism were organised via the Strength Through Joy program, and the 1936 Summer Olympics showcased the Third Reich on the international stage. Propaganda minister Joseph Goebbels made effective use of film, mass rallies, the government controlled artistic expression, promoting specific art forms and banning or discouraging others. Beginning in the late 1930s, Nazi Germany made increasingly aggressive territorial demands and it seized Austria and Czechoslovakia in 1938 and 1939. Hitler made a pact with Joseph Stalin and invaded Poland in September 1939. In alliance with Italy and smaller Axis powers, Germany conquered most of Europe by 1940, reichskommissariats took control of conquered areas, and a German administration was established in what was left of Poland. Jews and others deemed undesirable were imprisoned, murdered in Nazi concentration camps and extermination camps, following the German invasion of the Soviet Union in 1941, the tide gradually turned against the Nazis, who suffered major military defeats in 1943

Nazism
–
National Socialism, more commonly known as Nazism, is the ideology and practice associated with the 20th-century German Nazi Party and Nazi Germany, as well as other far-right groups. Nazism subscribed to theories of racial hierarchy and Social Darwinism, identifying Germans as part of what Nazis regarded as an Aryan or Nordic master race and it aimed to overcome social divisions and create a homogeneous society, unified on the basis of racial purity. The term National Socialism arose out of attempts to create a nationalist redefinition of socialism, the Nazi Partys precursor, the Pan-German nationalist and anti-Semitic German Workers Party, was founded on 5 January 1919. By the early 1920s, Adolf Hitler assumed control of the organisation, following the Holocaust and German defeat in World War II, only a few fringe racist groups, usually referred to as neo-Nazis, still describe themselves as following National Socialism. The full name of Adolf Hitlers party was Nationalsozialistische Deutsche Arbeiterpartei, the shorthand Nazi was formed from the first two syllables of the German pronunciation of the word national. The term was in use before the rise of the NSDAP as a colloquial and derogatory word for a peasant, characterizing an awkward. It derived from Ignaz, being a version of Ignatius, a common name in Bavaria. Opponents seized on this and shortened the first word of the name, Nationalsozialistische. The NSDAP briefly adopted the Nazi designation, attempting to reappropriate the term, the use of Nazi Germany, Nazi regime, and so on was popularised by German exiles abroad. From them, the spread into other languages and was eventually brought back to Germany after World War II. In English, Nazism is a name for the ideology the party advocated. The majority of scholars identify Nazism in practice as a form of far-right politics, far-right themes in Nazism include the argument that superior people have a right to dominate over other people and purge society of supposed inferior elements. Adolf Hitler and other proponents officially portrayed Nazism as being neither left- nor right-wing, but the politicians of the Right deserve exactly the same reproach. It was through their miserable cowardice that those ruffians of Jews who came into power in 1918 were able to rob the nation of its arms, a major inspiration for the Nazis were the far-right nationalist Freikorps, paramilitary organisations that engaged in political violence after World War I. The Nazis stated the alliance was purely tactical and there remained substantial differences with the DNVP, the Nazis described the DNVP as a bourgeois party and called themselves an anti-bourgeois party. After the elections in 1932, the alliance broke after the DNVP lost many of its seats in the Reichstag, the Nazis denounced them as an insignificant heap of reactionaries. The DNVP responded by denouncing the Nazis for their socialism, their violence. Kaiser Wilhelm II, who was pressured to abdicate the throne and flee into exile amidst an attempted communist revolution in Germany, there were factions in the Nazi Party, both conservative and radical

Teutonic Order
–
The Order of Brothers of the German House of Saint Mary in Jerusalem, commonly the Teutonic Order, is a Catholic religious order founded as a military order in the 12th century in Acre. Purely religious since 1929, it still confers limited honorary knighthoods, the order was formed to aid Christians on their pilgrimages to the Holy Land and to establish hospitals. Formed in the year 1190 in Acre, in the Levant, after Christian forces were defeated in the Middle East, the Order moved to Transylvania in 1211 to help defend the South-Eastern borders of the Kingdom of Hungary against the Kipchaks. Starting from there, the Order created the independent Monastic State of the Teutonic Knights, adding continuously the conquered Prussians territory, the Order theoretically lost its main purpose in Europe with the Christianization of Lithuania. However, it initiated numerous campaigns against its Christian neighbours, the Kingdom of Poland, the Grand Duchy of Lithuania, and the Novgorod Republic. The Teutonic Knights had an economic base, and so hired mercenaries from throughout Europe to augment their feudal levies. In 1410, a Polish-Lithuanian army decisively defeated the Order and broke its military power at the Battle of Grunwald, however, the capital of the Teutonic Knights was successfully defended in the following Siege of Marienburg and the Order was saved from collapse. In 1515, Holy Roman Emperor Maximilian I made an alliance with Sigismund I of Poland-Lithuania. Thereafter, the empire did not support the Order against Poland, in 1525, Grand Master Albert of Brandenburg resigned and converted to Lutheranism, becoming Duke of Prussia as a vassal of Poland. Soon after, the Order lost Livonia and its holdings in the Protestant areas of Germany, the Order did keep its considerable holdings in Catholic areas of Germany until 1809, when Napoleon Bonaparte ordered its dissolution and the Order lost its last secular holdings. However, the Order continued to exist as a charitable and ceremonial body and it was outlawed by Adolf Hitler in 1938, but re-established in 1945. Today it operates primarily with charitable aims in Central Europe, the Knights wore white surcoats with a black cross. A cross pattée was sometimes used as their coat of arms, the motto of the Order was, Helfen, Wehren, Heilen. The full name of the Order in German is Orden der Brüder vom Deutschen Haus St. Mariens in Jerusalem or in Latin Ordo domus Sanctæ Mariæ Theutonicorum Hierosolymitanorum, thus, the term Teutonic refers to the German origins of the order in Latin. It is commonly known in German as the Deutscher Orden, historically also as Deutscher Ritterorden, Deutschherrenorden, Deutschritterorden or Die Herren im weißen Mantel. However, based on the model of the Knights Templar, it was transformed into an order in 1198. It received papal orders for crusades to take and hold Jerusalem for Christianity, during the rule of Grand Master Hermann von Salza the Order changed from being a hospice brotherhood for pilgrims to primarily a military order. The Order was founded in Acre, and the Knights purchased Montfort, northeast of Acre, the Order also had a castle at Amouda in Armenia Minor

Prussia
–
Prussia was a historic state originating out of the Duchy of Prussia and the Margraviate of Brandenburg, and centred on the region of Prussia. For centuries, the House of Hohenzollern ruled Prussia, successfully expanding its size by way of an unusually well-organised, Prussia, with its capital in Königsberg and from 1701 in Berlin, shaped the history of Germany. In 1871, German states united to create the German Empire under Prussian leadership, in November 1918, the monarchies were abolished and the nobility lost its political power during the German Revolution of 1918–19. The Kingdom of Prussia was thus abolished in favour of a republic—the Free State of Prussia, from 1933, Prussia lost its independence as a result of the Prussian coup, when the Nazi regime was successfully establishing its Gleichschaltung laws in pursuit of a unitary state. Prussia existed de jure until its liquidation by the Allied Control Council Enactment No.46 of 25 February 1947. The name Prussia derives from the Old Prussians, in the 13th century, the Teutonic Knights—an organized Catholic medieval military order of German crusaders—conquered the lands inhabited by them. In 1308, the Teutonic Knights conquered the region of Pomerelia with Gdańsk and 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 Second Peace of Thorn split Prussia into the western Royal Prussia, a province of Poland, and the part, from 1525 called the Duchy of Prussia. The union of Brandenburg and the Duchy of Prussia in 1618 led to the proclamation of the Kingdom of Prussia in 1701, Prussia entered the ranks of the great powers shortly after becoming a kingdom, and exercised most influence in the 18th and 19th centuries. During the 18th century it had a say in many international affairs under the reign of Frederick the Great. During the 19th century, Chancellor Otto von Bismarck united the German principalities into a Lesser Germany which excluded the Austrian Empire. At the Congress of Vienna, which redrew the map of Europe following Napoleons defeat, Prussia acquired a section of north western Germany. The country then grew rapidly in influence economically and politically, and became the core of the North German Confederation in 1867, and then of the German Empire in 1871. The Kingdom of Prussia was now so large and so dominant in the new Germany that Junkers and other Prussian élites identified more and more as Germans and less as Prussians. In the Weimar Republic, the state of Prussia lost nearly all of its legal and political importance following the 1932 coup led by Franz von Papen. East Prussia lost all of its German population after 1945, as Poland, the main coat of arms of Prussia, as well as the flag of Prussia, depicted a black eagle on a white background. The black and white colours were already used by the Teutonic Knights. The Teutonic Order wore a white coat embroidered with a cross with gold insert
