83-458: The name Hohenstaufen was first used in the 14th century to distinguish the 'high' ( hohen ) conical hill named Staufen in the Swabian Jura (in the district of Göppingen ) from the village of the same name in the valley below. The new name was applied to the hill castle of Staufen by historians only in the 19th century to distinguish it from other castles of the same name. The name of

166-659: A document of emperor Otto III in 987 as descendants of counts of the region of Riesgau near Nördlingen in the Duchy of Swabia , who were related to the Bavarian Sieghardinger family. A local count Frederick (d. about 1075) is mentioned as progenitor in a pedigree drawn up by Abbot Wibald of Stavelot at the behest of Emperor Frederick Barbarossa in 1153. He held the office of a Swabian count palatine ; his son Frederick of Büren ( c.  1020 –1053) married Hildegard of Egisheim - Dagsburg (d. 1094/95),

249-648: A huge ransom in 1193. Henry died at Brunswick in 1195. Henry the Lion's son, Otto of Brunswick, was elected King of the Romans and crowned Holy Roman Emperor Otto IV after years of further conflicts with the Hohenstaufen emperors. He incurred the wrath of Pope Innocent III and was excommunicated in 1215. Otto was forced to abdicate the imperial throne by the Hohenstaufen Frederick II . He

332-458: A largely free class of officials previously formed, many of these assumed or acquired hereditary rights to administrative and legal offices. These trends compounded political fragmentation within Germany. The period was ended in 1273 with the election of Rudolph of Habsburg , a godson of Frederick. Conrad IV was succeeded as duke of Swabia by his only son, two-year-old Conradin . By this time,

415-537: A niece of Pope Leo IX . Their son Frederick I was appointed Duke of Swabia at Hohenstaufen Castle by the Salian king Henry IV of Germany in 1079. At the same time, Duke Frederick I was engaged to the king's approximately seventeen-year-old daughter, Agnes . Nothing is known about Frederick's life before this event, but he proved to be an imperial ally throughout Henry's struggles against other Swabian lords, namely Rudolf of Rheinfelden , Frederick's predecessor, and

498-654: A noble house in Germany. Henry IX, Duke of Bavaria , from 1120 to 1126, was the first of the three dukes of the Welf dynasty called Henry. His wife Wulfhild was the heiress of the house of Billung , possessing the territory around Lüneburg in Lower Saxony. Their son, Henry the Proud , was the son-in-law and heir of Lothair II, Holy Roman Emperor and became also Duke of Saxony on Lothair's death. Lothair left his territory around Brunswick , inherited from his mother of

581-598: A result of increasing tensions with the townsfolk of Brunswick , the Brunswick Line moved their residence to Wolfenbüttel Castle , thus the name Wolfenbüttel became the unofficial name of this principality. With Ivan VI of Russia the Brunswick line even had a short intermezzo on the Russian imperial throne in 1740. Not until 1754 was the residence moved back to Brunswick, into the new Brunswick Palace . In 1814

664-765: A role in the Investiture Controversy . Since the Welf dynasty sided with the Pope in this controversy, partisans of the Pope came to be known in Italy as Guelphs ( Guelfi ). The first genealogy of the Welfs is the Genealogia Welforum , composed shortly before 1126. A much more detailed history of the dynasty, the Historia Welforum , was composed around 1170. It is the earliest history of

747-496: A steep-sided, isolated hill or mountain, because they are not always seen or described in connexion with volcanic processes. All stratovolcanoes and shield volcanoes have a tendency to form a cone at the surface. However, stratovolcanoes are able to form steeper sides whilst shield volcanoes only form very flat cones. The reason for this is that stratovolcanoes are composed largely of solid, eruptive material, whereas shield volcanoes are built up mainly by fluid lava flows. Over

830-564: A time when anti-Catholic sentiment ran high in much of Northern Europe and Great Britain. Sophia died shortly before her first cousin once removed, Anne, Queen of Great Britain , the last sovereign of the House of Stuart . Sophia's son George I succeeded Queen Anne and formed a personal union from 1714 between the British crown and the Electorate of Hanover, which lasted until well after

In this work, which was published by Naumann and later revised by Bernhard Cotta , the most important hills are described in the relevant map sheets, for example: 33. The Mittenberg , a conical hill in the centre between Tollenstein , Schönfeld and Neuhütte; rock, coarse splinters, with grey feldspar crystals. Today the descriptors "cone", "conical hill" or "conical mountain" are mainly used as morphological terms in geography for

996-425: A wholesale denuding of royal power and it did not prevent imperial officials from enforcing Frederick’s prerogatives. The Statutum affirmed a division of labor between the emperor and the princes and laid much groundwork for the development of particularism and, perhaps even federalism in Germany. Even so, from 1232 the vassals of the emperor had a veto over imperial legislative decisions and any new law established by

1079-404: Is Queen Frederica's nephew Ernst August , the third and present husband of Princess Caroline of Monaco . In 1129, after Henry the Proud's defeat against Lothair III, Holy Roman Emperor , his sister Sophia was given a seat at Regensburg . From c.  1150 until his death in 1167, Welf VI's son, Welf VII, was associated to his father, but predeceased him. After Welf VI's death, Altdorf

1162-612: Is a European dynasty that has included many German and British monarchs from the 11th to 20th century and Emperor Ivan VI of Russia in the 18th century. The originally Franconian family from the Meuse-Moselle area was closely related to the imperial family of the Carolingians . The (Younger) House of Welf is the older branch of the House of Este , a dynasty whose earliest known members lived in Veneto and Lombardy in

1245-402: Is generally so wonderfully uniform that you can often recognize them even from a distance. They are cones. Of course, this typical form has many variations; the [normally] round base may be elongated, the peak may take the form of a rocky crest or ridge, ... but most forms can be reduced at least to a conical or a cone-segment shape. ... Flat ridges are then arranged in rows, out of which rise only

1328-507: Is often of volcanic origin. Conical hills or mountains occur in different shapes and are not necessarily geometrically-shaped cones; some are more tower-shaped or have an asymmetric curve on one side of the hill. Typically, however, they have a circular base and smooth sides with a gradient of up to 30°. Such conical mountains are found in all volcanically-formed areas of the world such as the Bohemian Central Uplands in

1411-533: Is shown clearly in the imperial Landfried issued at Mainz in 1235, which explicitly enjoined the princes as loyal vassals to exercise their own jurisdictions in their own localities. The jurisdictional autarky of the German princes was favoured by the crown itself in the twelfth and thirteenth centuries in the interests of order and local peace. The inevitable result was the territorial particularism of churchmen, lay princes, and interstitial cities. However, Frederick II

1494-403: Is unlikely that a particularly “strong ruler” such as Frederick II would have even pragmatically agreed to legislation that was concessionary rather than cooperative, neither would the princes have insisted on such. Frederick II used the political loyalty and practical jurisdictions of the German aristocracy to support his kingly duty of imposing peace, order, and justice upon the German realm. This

According to the provisions of the Treaty of Hanover from the year 1373, after the death of Wensceslas, the Principality passed to the House of Welf. In 1389, an inheritance agreement between the Welfs and the Ascanians was concluded,

1660-536: The Brunonids , to his daughter Gertrud. Her husband Henry the Proud became then the favoured candidate in the imperial election against Conrad III of the Hohenstaufen . Henry lost the election, as the other princes feared his power and temperament, and was dispossessed of his duchies by Conrad III. Henry's brother Welf VI (1115–1191), Margrave of Tuscany, later left his Swabian territories around Ravensburg,

1743-1015: The Chocolate Hills in Bohol on the Philippines . In almost all mountain regions of the world, conical peaks may be formed by erosion processes, but they are not usually isolated landforms. Often they arise through the formation of ordinary riverine meanders . But they can also result from the action of an entrenched river that has cut deeply into a plateau . The resulting cutoff meander spur may be cone-shaped. The artificially created hills or mounds associated, for example, with mining also tend to be cone-shaped. These artificial hills are also free-standing and, once tipping has finished, they may become conical hills overgrown with vegetation. However, as artificial features they are classed as spoil tips rather than natural hills. House of Welf The House of Welf (also Guelf or Guelph )

1826-752: The Czech Republic , the Rhön in Germany or the Massif Central in France . The conical hill as a geomorphological term first appeared in the German language, as Kegelberg , coined by Goethe and geologists of his era. From their natural appearance these were mostly basaltic or phonolitic landforms in the shape of a mathematical cone, hence why the term came to be used in the early geological literature. The first systematic geological mapping of

1909-623: The House of Luneburg residing at Celle Castle . In 1635 it was given to George , younger brother of Prince Ernest II of Lüneburg , who chose Hanover as his residence. New territory was added in 1665, and in 1705 the Principality of Luneburg was taken over by the Hanoverians. In 1692 Duke Ernest Augustus from the Calenberg-Hanover Line acquired the right to be a prince-elector of the Holy Roman Empire as

1992-522: The Investiture Controversy under his Salian predecessors. As royal access to the resources of the church in Germany was much reduced, Frederick was forced to go to Italy to find the finances needed to restore the king's power in Germany. He was soon crowned emperor in Italy, but decades of warfare on the peninsula yielded scant results. The Papacy and the prosperous city-states of the Lombard League in northern Italy were traditional enemies, but

2075-593: The King of the Romans ) through a customary election, but lost to the Saxon duke Lothair of Supplinburg . A civil war between Frederick's dynasty and Lothair's ended with Frederick's submission in 1134. After Lothair's death in 1137, Frederick's brother Conrad was elected King as Conrad III. Because the Welf duke Henry the Proud , son-in-law and heir of Lothair and the most powerful prince in Germany, who had been passed over in

2158-816: The Kingdom of Saxony , proposed and started by Abraham Gottlob Werner , describes, in his later works, numerous mountains and hills of volcanic or subvolcanic origin as Kegel ("cone") or Kegelberg ("conical hill/mountain"). The term was introduced more definitively by Carl Friedrich Naumann in Notes to Section VII of the Geognostic Charter of the Kingdom of Saxony and its Adjacent Territories ( Erläuterungen zu Section VII der geognostischen Charte des Königreiches Sachsen und der angränzenden Länderabtheilungen ) thus: "The ordinary form of basalt and phonolitic hills

2241-421: The Kingdom of Sicily in 1189 and 1194 respectively, a source of vast wealth. Henry failed to make royal and Imperial succession hereditary, but in 1196 he succeeded in gaining a pledge that his infant son Frederick would receive the German crown. Faced with difficulties in Italy and confident that he would realize his wishes in Germany at a later date, Henry returned to the south, where it appeared he might unify

Elected king even before his father's death, Henry went to Rome to be crowned emperor. He married Princess Constance of Sicily , and deaths in his wife's family gave him claim of succession and possession of

2407-643: The Prince-Elector of Brunswick-Lüneburg . Colloquially the Electorate was known as the Electorate of Hanover . In 1814 it was succeeded by the Kingdom of Hanover . Religion-driven politics placed Ernest Augustus's wife Sophia of the Palatinate in the line of succession to the British crown by the Act of Settlement 1701 , written to ensure a Protestant succession to the thrones of Scotland and England at

2490-642: The Silesian dukes of the Piast dynasty. With the German colonization, the Empire increased in size and came to include the Duchy of Pomerania . A quickening economic life in Germany increased the number of towns and Imperial cities , and gave them greater importance. It was also during this period that castles and courts replaced monasteries as centers of culture. Growing out of this courtly culture, Middle High German literature reached its peak in lyrical love poetry,

2573-585: The Zähringen and Welf lords. Frederick's brother Otto was elevated to the Strasbourg bishopric in 1082. Upon Frederick's death, he was succeeded by his son, Duke Frederick II , in 1105. Frederick II remained a close ally of the Salians, he and his younger brother Conrad were named the king's representatives in Germany when the king was in Italy. Around 1120, Frederick II married Judith of Bavaria from

The exact connection between the family and Waiblingen is not clear, but as a name for the family, it became very popular. The pro-imperial Ghibelline faction of the Italian civic rivalries of the 13th and 14th centuries derived its name from Waiblingen. In Italian historiography, the Staufer are known as the Svevi (Swabians). The origin remains unclear, however, Staufer counts are mentioned in

The power struggle with the popes continued and resulted in Frederick's excommunication in 1227. In 1239, Pope Gregory IX excommunicated Frederick again, and in 1245 he was condemned as a heretic by a church council.

Bavaria had been given to Otto I, Duke of Bavaria , and the Duchy of Saxony was divided between the Archbishop of Cologne, the House of Ascania and others. Diminished lands did not prevent him from imprisoning Richard I on his return from the Third Crusade , and demanding

His main concerns lay in Italy and the Kingdom of Sicily, where he ruled as an absolute monarch supported by a sophisticated administrative apparatus. The institutions of Sicily and Italy seemed to be better political laboratories, more conducive to Frederick’s remarkable brand of innovation and absolutist tendencies. He founded the University of Naples in 1224 to train future state officials and reigned over Germany primarily through

Dispossessed of his duchies after the Battle of Legnano in 1176 by Emperor Frederick I and the other princes of the German Empire eager to claim parts of his vast territories, he was exiled to the court of his father-in-law Henry II in Normandy in 1180. He returned to Germany three years later. Henry made his peace with

3237-814: The Kingdom of Sicily. The sophistication of the Constitutions or the Liber Augustalis set Frederick as perhaps the supreme lawgiver of the Middle Ages. The Constitutions drew upon decades of Siculo-Norman governmental tradition stretching back to his maternal grandfather, Roger II of Sicily . Almost every aspect in Frederick’s tightly-governed kingdom was regulated, from a rigorously centralized judiciary and bureaucracy, to commerce, coinage, financial policy, weights and measures, legal equality for all citizens, protections for women, and even provisions for

The German princes vied for individual advantage and managed to strip many powers away from the diminished monarchy. Rather than establish sovereign states however, many nobles tended to look after their families. Their many male heirs created more and smaller estates, and from

Frederick had returned to Germany in 1212 from Sicily, where he had grown up, and was elected king in 1215. When Otto died in 1218, Frederick became the undisputed ruler, and in 1220

3652-538: The allocation of royal prerogatives, leaving the sovereign authority and imperial estates to the ecclesiastical and secular princes. In 1232, Henry (VII), King of Germany and Frederick’s eldest son, was forced by the German princes to promulgate the Statutum in favorem principum ("statute in favor of princes"). Frederick II, embittered but aiming to promote cohesion in Germany in preparation for his campaigns in northern Italy, pragmatically agreed to Henry’s confirmation of

3735-668: The boy's uncle, Duke Philip of Swabia , brother of late Henry VI, was designated to serve in his place. Other factions however favoured a Welf candidate. In 1198, two rival kings were chosen: the Hohenstaufen Philip of Swabia and the son of the deprived Duke Henry the Lion , the Welf Otto IV . A long civil war began; Philip was about to win when he was murdered by the Bavarian count palatine Otto VIII of Wittelsbach in 1208. Pope Innocent III initially had supported

3818-441: The charter. It was a charter of liberties for the leading German princes at the expense of the lesser nobility and the entirety of the commoners. The princes gained whole power of jurisdiction, and the power to strike their own coins. The emperor lost his right to establish new cities, castles and mints over their territories. The Statutum was more a confirmation of political realities which had existed for generations in Germany than

The natural conical shape so formed is simply a result of the fact that the amount of ejected material decreases with the radially distance from the crater . The layer of debris deposited is greater near the volcano than further away, so the volcano grows more rapidly close to the crater itself. The slope gradient of

His rule there was short-lived, as the monarchy came to an end following the First World War in 1918. The Welf dynasty continues to exist. The last member sitting on a European throne was Frederica of Hanover , Queen of Greece († 1981), mother of Queen Sofia of Spain and King Constantine II of Greece . Frederica's brother Prince George William of Hanover married Princess Sophie of Greece and Denmark , sister of Prince Philip, Duke of Edinburgh . The House's head

4067-461: The dynasty followed suit, but in recent decades, the trend in German historiography has been to prefer the name 'Staufer', which is closer to contemporary usage. The name 'Staufen' itself derives from Stauf ( OHG stouf , akin to Early Modern English stoup ), meaning ' chalice '. This term was commonly applied to conical hills in Swabia during the Middle Ages. It is a contemporary term for both

In 1147, Conrad heard Bernard of Clairvaux preach the Second Crusade at Speyer , and he agreed to join King Louis VII of France in a great expedition to the Holy Land which failed. Conrad's brother Duke Frederick II died in 1147, and

4233-408: The emperor had to be approved by the princes. These provisions not withstanding, royal power in Germany remained strong under Frederick. By the 1240s the crown was almost as rich in fiscal resources, towns, castles, enfeoffed retinues, monasteries, ecclesiastical advocacies, manors, tolls, and all other rights, revenues, and jurisdictions as it had ever been at any time since the death of Henry VI. It

The British royal family became known as the House of Hanover . The "Electorate of Hanover" (the core duchy) was enlarged with the addition of other lands and became the Kingdom of Hanover in 1814 at the Congress of Vienna . During the first half of

4399-415: The entire Middle Ages, he seemed to be less concerned with drawing the disparate forces in Germany together. Frederick was pragmatic enough to realize that for all his ability and power, his time and focus could only be fully concentrated either north or south of the Alps, where the bulk of his resources lay. Frederick II’s most profound legal legacy remains the Constitutions of Melfi promulgated in 1231 in

4482-458: The environment and public health. Per the Constitutions, Frederick II was lex animata and ruled as an absolute monarch. The Constitutions have been regarded as perhaps the “birth certificate” of the modern continental European state. From 1240, Frederick II was determined to push through far-reaching reforms to establish the Sicilian kingdom and Imperial Italy as a unified state bound by a centralized administration. The new unified administration

4565-421: The estates, which was to supervise the treaty. However, 1373–1388 would be the only period in which a Brunswick-Luneburg land was not ruled by a Welf: In the wake of his death, Elector Wenceslas appointed Bernard, his brother-in-law, as co-regent involved him in the government. But his younger brother Henry did not agree with this ruling, and after vain attempts to reach an agreement, the fight flared up again in

4648-409: The fear of Imperial domination caused them to join ranks to fight Frederick. Under the skilled leadership of Pope Alexander III , the alliance suffered many defeats but ultimately was able to deny the emperor a complete victory in Italy. Frederick returned to Germany. He had vanquished one notable opponent, his Welf cousin, Duke Henry the Lion of Saxony and Bavaria in 1180, but his hopes of restoring

4731-400: The hill and the castle, although its spelling in the Latin documents of the time varies considerably: Sthouf, Stophe, Stophen, Stoyphe, Estufin , etc. The castle was built or at least acquired by Duke Frederick I of Swabia in the latter half of the 11th century. Members of the family occasionally used the toponymic surname de Stauf or variants thereof. Only in the 13th century would

He inherited the property of the Elder House of Welf when his maternal uncle Welf III , Duke of Carinthia and Verona, the last male Welf of the Elder House, died in 1055. Welf IV was the son of Welf III's sister Kunigunde of Altdorf and her husband Albert Azzo II, Margrave of Milan . In 1070, Welf IV became Duke of Bavaria . Welf II, Duke of Bavaria married Countess Matilda of Tuscany , who died childless and left him her possessions, including Tuscany , Ferrara , Modena , Mantua , and Reggio , which played

4897-401: The late Staufer period, the population had grown from an estimated 8 million in 1200 to about 14 million in 1300, and the number of towns increased tenfold. The most heavily urbanized areas of Germany were in the south and the west. Towns often developed a degree of independence, but many were subordinate to local rulers if not immediate to the emperor. Colonization of the east also continued in

In 1247, the Emperor Frederick II himself referred to his family as the domus Stoffensis (Staufer house), but this was an isolated instance. Otto of Freising (d. 1158) associated the Staufer with the town of Waiblingen , and around 1230, Burchard of Ursberg referred to the Staufer as of

5063-416: The nineteenth century, the Kingdom was ruled as personal union by the British crown from its creation under George III of the United Kingdom, the last elector of Hanover until the death of William IV in 1837. At that point, the crown of Hanover went to William's younger brother, Ernest Augustus, Duke of Cumberland and Teviotdale under the Salic law requiring the next male heir to inherit, whereas

In 1261, attempts to elect young Conradin king were unsuccessful. He also had to defend Sicily against an invasion, sponsored by Pope Urban IV (Jacques Pantaléon) and Pope Clement IV (Guy Folques), by Charles of Anjou , a brother of the French king. Charles had been promised by

5229-537: The original possessions of the Elder House of Welf , to his nephew Emperor Frederick I , and thus to the House of Hohenstaufen. The next duke of the Welf dynasty Henry the Lion (1129/1131–1195) recovered his father's two duchies, Saxony in 1142, Bavaria in 1156 and thus ruled vast parts of Germany. In 1168 he married Matilda (1156–1189), the daughter of Henry II of England and Eleanor of Aquitaine , and sister of Richard I of England , gaining ever more influence. His first cousin, Frederick I, Holy Roman Emperor of

His underage son Frederick could only succeed him in Sicily and Malta, while in the Empire the struggle between the House of Staufen and the House of Welf erupted once again. Because the election of a three-year-old boy to be German king appeared likely to make orderly rule difficult,

Charles had defeated Conradin's uncle Manfred, King of Sicily , in the Battle of Benevento on 26 February 1266. The king himself, refusing to flee, rushed into the midst of his enemies and was killed. Conradin's campaign to retake control ended with his defeat in 1268 at the Battle of Tagliacozzo , after which he

5478-444: The power and prestige of the monarchy seemed unlikely to be met by the end of his life. During Frederick's long stays in Italy, the German princes became stronger and began a successful colonization of Slavic lands. Offers of reduced taxes and manorial duties enticed many Germans to settle in the east in the course of the Ostsiedlung . In 1163 Frederick waged a successful campaign against the Kingdom of Poland in order to re-install

5561-409: The principality became the Duchy of Brunswick , ruled by the senior branch of the House of Welf. In 1432 the estates gained by the Principality of Brunswick-Wolfenbüttel between the Deister and Leine split away as the Principality of Calenberg . In 1495 it was expanded around Göttingen and in 1584 went back to the Wolfenbüttel Line. In 1634, as a result of inheritance distributions, it went to

By the time of Frederick's death in 1250, the crown in Germany was still formidable and Conrad IV , Frederick’s eldest surviving legitimate son and heir, enjoyed a strong position. However after Conrad’s death in 1254, The Great Interregnum followed which saw several rival claimants elected as King of

The angle of repose is, in turn, dependent on the composition of the lava , its viscosity and rate of solidification, and also the amount of ejected loose rock . Many volcanoes tend to produce subsidiary craters or adventive cones . These are new openings formed on the sides of

5810-410: The rival House of Welf . When the last male member of the Salian dynasty, Emperor Henry V , died without heirs in 1125, a controversy arose about the succession.
