Holy Roman Emperor in the context of "Carolingian dynasty"

The East–West Schism, also known as the Great Schism or the Schism of 1054, is the break of communion between the Catholic Church and the Eastern Orthodox Church since 1054. A series of ecclesiastical differences, theological disputes and geopolitical tensions between the Greek East and Latin West preceded the formal split that occurred in 1054. Prominent among these were the procession of the Holy Spirit (Filioque), whether leavened or unleavened bread should be used in the Eucharist, iconoclasm, the coronation of Charlemagne as emperor of the Romans in 800, the pope's claim to universal jurisdiction, and the place of the See of Constantinople in relation to the pentarchy.

The first action that led to a formal schism occurred in 1053 when Patriarch Michael I Cerularius of Constantinople ordered the closure of all Latin churches in Constantinople. In 1054, the papal legate sent by Leo IX travelled to Constantinople in order, among other things, to deny Cerularius the title of "ecumenical patriarch" and insist that he recognize the pope's claim to be the head of all of the churches. The main purposes of the papal legation were to seek help from the Byzantine emperor, Constantine IX Monomachos, in view of the Norman conquest of southern Italy, and to respond to Leo of Ohrid's attacks on the use of unleavened bread and other Western customs, attacks that had the support of Cerularius. The historian Axel Bayer says that the legation was sent in response to two letters, one from the emperor seeking help to organize a joint military campaign by the eastern and western empires against the Normans, and the other from Cerularius. When the leader of the legation, Cardinal Humbert of Silva Candida, O.S.B., learned that Cerularius had refused to accept the demand, he excommunicated him, and in response Cerularius excommunicated Humbert and the other legates. According to Kallistos Ware, "Even after 1054 friendly relations between East and West continued. The two parts of Christendom were not yet conscious of a great gulf of separation between them ... The dispute remained something of which ordinary Christians in East and West were largely unaware".

The Codex Aureus of Saint Emmeram (Munich, Bayerische Staatsbibliothek, Clm 14000) is a 9th-century illuminated Gospel Book. It takes its name from Saint Emmeram's Abbey in Bavaria, where it was for most of its history (named after Emmeram of Regensburg) and is lavishly illuminated. The cover of the codex is decorated with gems and relief figures in gold, can be precisely dated to 870, and is an important example of Carolingian art, as well as one of very few surviving treasure bindings of this date.

The upper cover of the Lindau Gospels is probably a product of the same workshop, though there are differences of style. This workshop is associated with the Holy Roman Emperor Charles II (the Bald), and often called his "Palace School". Its location (if it had a fixed one) remains uncertain and much discussed, but Saint-Denis Abbey outside Paris is one leading possibility. The Arnulf Ciborium (a miniature architectural ciborium rather than the vessel for hosts), now in the Munich Residenz, is the third major work in the group, along with the frame of an antique serpentine dish in the Louvre. Recent scholars tend to group the Lindau Gospels and the Arnulf Ciborium in closer relation to each other than the Codex Aureus to either.

The history of Italy in the Middle Ages can be roughly defined as the time between the collapse of the Western Roman Empire and the Italian Renaissance. Late antiquity in Italy lingered on into the 7th century under the Ostrogothic Kingdom and the Byzantine Empire under the Justinian dynasty, the Byzantine Papacy until the mid 8th century. The "Middle Ages" proper begin as the Byzantine Empire was weakening under the pressure of the Muslim conquests, and most of the Exarchate of Ravenna finally fell under Lombard rule in 751. From this period, former states that were part of the Exarchate and were not conquered by the Lombard Kingdom, such as the Duchy of Naples, became de facto independent states, having less and less interference from the Eastern Roman Empire.

Lombard rule ended with the invasion of Charlemagne in 773, who established the Kingdom of Italy and the Papal States in large parts of Northern and Central Italy. This set the precedent for the main political conflict in Italy over the following centuries, between the Pope and the Holy Roman Emperor, culminating with conflict between Pope Gregory VII and Henry IV and the latter's "Walk to Canossa" in 1077.

Charles V (24 February 1500 – 21 September 1558) was Holy Roman Emperor and Archduke of Austria from 1519 to 1556, King of Spain (as Charles I) from 1516 to 1556, King of Sicily and Naples from 1516 to 1554, and also Lord of the Netherlands and titular Duke of Burgundy (as Charles II) from 1506 to 1555. He was heir to and then head of the rising House of Habsburg. His dominions in Europe included the Holy Roman Empire, extending from Germany to northern Italy with rule over the Austrian hereditary lands and Burgundian Low Countries, and Spain with its possessions of the southern Italian kingdoms of Sicily, Naples, and Sardinia. In the Americas, he oversaw the continuation of Spanish colonization and a short-lived German colonization. The personal union of the European and American territories he ruled was the first collection of realms labelled "the empire on which the sun never sets".

Charles was born in Flanders to Habsburg Archduke Philip the Handsome, son of Maximilian I, Holy Roman Emperor and Mary of Burgundy, and Joanna of Castile, younger child of Isabella I of Castile and Ferdinand II of Aragon, the Catholic Monarchs of Spain. Heir of his grandparents, Charles inherited his family dominions at a young age. After his father's death in 1506, he inherited the Habsburg Netherlands in the Low Countries. In 1516 he became King of Spain as co-monarch of Castile and Aragon with his mother. Spain's possessions included the Castilian colonies of the West Indies and the Spanish Main, as well as Naples, Sicily, and Sardinia. At the death of his grandfather Maximilian in 1519, he inherited the Austrian hereditary lands and was elected as Holy Roman Emperor. He adopted the Imperial name of Charles V as his main title, and styled himself as a new Charlemagne.

Operation Barbarossa was the invasion of the Soviet Union by Nazi Germany and several of its European Axis allies starting on Sunday, 22 June 1941, during World War II. More than 3.8 million Axis troops invaded the western Soviet Union along a 2,900-kilometer (1,800 mi) front, with the main goal of capturing territory up to a line between Arkhangelsk and Astrakhan, known as the A–A line. The attack became the largest and costliest military offensive in human history, with around 10 million combatants taking part in the opening phase and over 8 million casualties by the end of the operation on 5 December 1941. It marked a major escalation of World War II, opened the Eastern Front—the largest and deadliest land war in history—and brought the Soviet Union into the Allied powers.

The operation, code-named after the Holy Roman Emperor Frederick Barbarossa ("red beard"), put into action Nazi Germany's ideological goals of eradicating communism and conquering the western Soviet Union to repopulate it with Germans under Generalplan Ost, which planned for the removal of the native Slavic peoples by mass deportation to Siberia, Germanisation, enslavement, and genocide. The material targets of the invasion were the agricultural and mineral resources of territories such as Ukraine and Byelorussia and oil fields in the Caucasus. The Axis eventually captured five million Soviet Red Army troops on the Eastern Front and deliberately starved to death or otherwise killed 3.3 million prisoners of war, as well as millions of civilians. Mass shootings and gassing operations, carried out by German paramilitary death squads and collaborators, murdered over a million Soviet Jews as part of the Holocaust.

Bamberg (/ˈbæmbɜːrɡ/, US also /ˈbɑːmbɛərk/, German: [ˈbambɛʁk] ; East Franconian: Bambärch) is a town in Upper Franconia, Bavaria, Germany, on the river Regnitz close to its confluence with the river Main. Bamberg had 79,000 inhabitants in 2022. The town dates back to the 9th century, when its name was derived from the nearby Babenberch castle. Cited as one of Germany's most beautiful towns, with medieval streets and buildings, the old town of Bamberg with around 2,400 timber houses has been a UNESCO World Heritage Site since 1993.

From the 10th century onwards, Bamberg became a key link with the Western Slavic peoples, notably those of Poland and Pomerania. It experienced a period of great prosperity from the 12th century onwards, during which time it was briefly the centre of the Holy Roman Empire. Emperor Henry II was buried in the old town, alongside his wife Kunigunde. The town's architecture from this period strongly influenced that in Northern Germany and Hungary. From the middle of the 13th century onwards, the bishops were princes of the Empire and ruled Bamberg, overseeing the construction of monumental buildings. This growth was complemented by the obtaining of large portions of the estates of the Counts of Meran in 1248 and 1260 by the sea, partly through purchase and partly through the appropriation of extinguished fiefs.

The Vienna Dioscurides or Vienna Dioscorides is an early 6th-century Byzantine Greek illuminated manuscript of an even earlier 1st century AD work, De materia medica (Ancient Greek: Περὶ ὕλης ἰατρικῆς, romanized: Perì hylēs iatrikēs) by Pedanius Dioscorides in uncial script. It is an important and rare example of a late antique scientific text. After residing in Constantinople for just over a thousand years, the text passed to the Holy Roman Emperor in Vienna in the 16th century, a century after the city fell to the Ottoman Empire.

The 491 vellum folios measure 37 cm (15 in) by 30 cm (12 in) and contain more than 400 pictures of animals and plants, most done in a naturalistic style. In addition to the text by Dioscorides, the manuscript has appended to it, the Carmen de herbis attributed to Rufus, a paraphrase of an ornithological treatise by a certain Dionysius, usually identified with Dionysius of Philadelphia, and a paraphrase of Nicander's treatise on the treatment of snake bites.

King is a royal title given to a male monarch. A king is an absolute monarch if he holds unrestricted governmental power or exercises full sovereignty over a nation. In a modern context, the title may refer to the ruler of one of a number of modern monarchies (either absolute or constitutional). The title of king is used alongside other titles for monarchs: in the West, emperor, grand prince, prince, archduke, duke or grand duke, and in the Islamic world, malik, sultan, emir or hakim, etc.

The term king may also refer to a king consort, a title that is sometimes given to the husband of a queen regnant, but the title of prince consort is more common.

The Electoral Palatinate was a constituent state of the Holy Roman Empire until it was annexed by the Electorate of Baden in 1803. From the end of the 13th century, its ruler was one of the Prince-electors who elected the Holy Roman Emperor, ranking them among the most significant secular Princes of the Holy Roman Empire.

The Palatinate consisted of a number of widely dispersed territories, ranging from the left bank of the Upper Rhine in the modern state of Rhineland-Palatinate, adjacent parts of the French regions of Alsace and Lorraine to the opposite territory on the east bank of the Rhine in present-day Hesse and Baden-Württemberg up to the Odenwald range and the southern Kraichgau region, containing the capital cities of Heidelberg and Mannheim.
