Charles I Of Sicily
Charles I (early 1226/12277 January 1285), commonly called Charles of Anjou, was a member of the royal Capetian dynasty and the founder of the second House of Anjou. He was Count of Provence (1246–85) and Forcalquier (1246–48, 1256–85) in the Holy Roman Empire, Count of Anjou and Maine (1246–85) in France; he was also King of Sicily (1266–85) and Prince of Achaea (1278–85). In 1272, he was proclaimed King of Albania, and in 1277 he purchased a claim to the Kingdom of Jerusalem. The youngest son of Louis VIII of France and Blanche of Castile, Charles was destined for a Church career until the early 1240s. He acquired Provence and Forcalquier through his marriage to their heiress, Beatrice. His attempts to restore central authority brought him into conflict with his mother-in-law, Beatrice of Savoy, and the nobility. Charles received Anjou and Maine from his brother, Louis IX of France, in appanage. He accompanied Louis during the Seventh Crusade to Egypt. Short ...

Second Barons' War
The Second Barons' War (1264–1267) was a civil war in England between the forces of a number of barons led by Simon de Montfort against the royalist forces of King Henry III, led initially by the king himself and later by his son, the future King Edward I. The barons sought to force the king to rule with a council of barons, rather than through his favourites. The war also involved a series of massacres of Jews by de Montfort's supporters, including his sons Henry and Simon, in attacks aimed at seizing and destroying evidence of baronial debts. To bolster the initial success of his baronial regime, de Montfort sought to broaden the social foundations of parliament by extending the franchise to the commons for the first time. However, after a rule of just over a year, de Montfort was killed by forces loyal to the king at the Battle of Evesham. Causes The reign of Henry III is most remembered for the constitutional crisis in this period of civil strife, which was provoked o ...

Treaty Of Montgomery
The Treaty of Montgomery was an Anglo-Welsh treaty signed on 29 September 1267 in Montgomeryshire by which Llywelyn ap Gruffudd was acknowledged as Prince of Wales by King Henry III of England (r. 1216–1272). It was the only time an English ruler recognised the right of a ruler of Gwynedd over Wales. Llywelyn's grandfather Llywelyn the Great had previously laid claim to be the effective prince of Wales by using the title "Prince of Aberffraw, Lord of Snowdon" in the 1230s, after subduing all the other Welsh dynasties. Likewise Llywelyn's uncle, Dafydd ap Llywelyn, claimed the title of Prince of Wales during his reign from 1240 to 1246. However, Llywelyn's supremacy in the late 1260s forced recognition of his authority in Wales by an English Crown weakened by internal division. Conditions of the treaty Many of the conditions of the treaty had been anticipated by the Treaty of Pipton (1265) between Llywelyn and Simon de Montfort. The 1267 treaty ceded Builth to Llywelyn, a ...

Pope Clement IV
Pope Clement IV ( la, Clemens IV; 23 November 1190 – 29 November 1268), born Gui Foucois ( la, Guido Falcodius; french: Guy de Foulques or ') and also known as Guy le Gros ( French for "Guy the Fat"; it, Guido il Grosso), was bishop of Le Puy (1257–1260), archbishop of Narbonne (1259–1261), cardinal of Sabina (1261–1265), and head of the Catholic Church from 5 February 1265 until his death. His election as pope occurred at a conclave held at Perugia that lasted four months while cardinals argued over whether to call in Charles I of Anjou, the youngest brother of Louis IX of France, to carry on the papal war against the Hohenstaufens. Pope Clement was a patron of Thomas Aquinas and of Roger Bacon, encouraging Bacon in the writing of his ''Opus Majus'', which included important treatises on optics and the scientific method. Early life Clement was born in Saint-Gilles-du-Gard in the Languedoc region of France, to a successful lawyer, Pierre Foucois, and his wife Margu ...

Roger Bacon
Roger Bacon (; la, Rogerus or ', also '' Rogerus''; ), also known by the scholastic accolade ''Doctor Mirabilis'', was a medieval English philosopher and Franciscan friar who placed considerable emphasis on the study of nature through empiricism. In the early modern era, he was regarded as a wizard and particularly famed for the story of his mechanical or necromantic brazen head. He is sometimes credited (mainly since the 19th century) as one of the earliest European advocates of the modern scientific method, along with his teacher Robert Grosseteste. Bacon applied the empirical method of Ibn al-Haytham (Alhazen) to observations in texts attributed to Aristotle. Bacon discovered the importance of empirical testing when the results he obtained were different from those that would have been predicted by Aristotle. His linguistic work has been heralded for its early exposition of a universal grammar, and 21st-century re-evaluations emphasise that Bacon was essentially a medi ...

Treaty Of Viterbo
The Treaty of Viterbo (or the Treaties of Viterbo) was a pair of agreements made by Charles I of Sicily with Baldwin II of Constantinople and William II Villehardouin, Prince of Achaea, on 24 and 27 May 1267, which transferred much of the rights to the defunct Latin Empire from Baldwin to Charles. Background The recapture of Constantinople by the Greeks in 1261 had sent Baldwin, the Latin Emperor of Constantinople, always impoverished, to seek aid in Western Europe for a crusade to recapture the throne of the Latin Empire for him. For some time, he had expected aid from Manfred of Sicily, who hoped (like his father, Emperor Frederick II) that a crusade might put him in better standing with the Papacy; but Manfred was ousted from Sicily in 1266 by Charles, acting for Pope Clement IV, severely discomfiting Baldwin. Baldwin was residing at the Papal court in Viterbo in 1267 when Clement arranged to reconcile the Emperor and the newly seated King. As the principal vassal of what remaine ...

Dictum Of Kenilworth
The Dictum of Kenilworth, issued on 31 October 1266, was a pronouncement designed to reconcile the rebels of the Second Barons' War with the royal government of England. After the baronial victory at the Battle of Lewes in 1264, Simon de Montfort took control of royal government, but at the Battle of Evesham the next year Montfort was killed, and King Henry III restored to power. A group of rebels held out in the stronghold of Kenilworth Castle, however, and their resistance proved difficult to crush. A siege of the castle was started, but through papal intervention King Henry later entered on a more conciliatory path. A commission was appointed to draw up an arrangement that would be acceptable to both sides. The resulting Dictum of Kenilworth offered the rebels the right to buy back forfeited estates, at prices depending on their level of involvement in the rebellion. After initial resistance, the terms were eventually accepted. By the summer of 1267, the country was pacifie ...

Henry III Of England
Henry III (1 October 1207 – 16 November 1272), also known as Henry of Winchester, was King of England, Lord of Ireland, and Duke of Aquitaine from 1216 until his death in 1272. The son of King John and Isabella of Angoulême, Henry assumed the throne when he was only nine in the middle of the First Barons' War. Cardinal Guala Bicchieri declared the war against the rebel barons to be a religious crusade and Henry's forces, led by William Marshal, defeated the rebels at the battles of Lincoln and Sandwich in 1217. Henry promised to abide by the Great Charter of 1225, a later version of the 1215 '' Magna Carta'', which limited royal power and protected the rights of the major barons. His early rule was dominated first by Hubert de Burgh and then Peter des Roches, who re-established royal authority after the war. In 1230, the King attempted to reconquer the provinces of France that had once belonged to his father, but the invasion was a debacle. A revolt led by William ...

Kingdom Of The Algarve
The Kingdom of the Algarve (Portuguese: ''Reino do Algarve'', from the Arabic ''Gharb al-Andalus'' ), after 1471 Kingdom of the Algarves (Portuguese: ''Reino dos Algarves''), was a nominal kingdom within the Kingdom of Portugal, located in the southernmost region of continental Portugal. It was a dominion of the Portuguese Crown and supposedly a kingdom apart from Portugal, though in fact the "Algarvian kingdom" had no institutions, special privileges, or autonomy. The Algarve was politically very similar to the rest of the Portuguese provinces, and "King of the Algarve" was just an honorific title, based on the Algarve's history as the last area of Portugal to be conquered from the Moors during the Portuguese Reconquista. The title ''King of Silves'' was first used by Sancho I of Portugal after the first conquest of the Algarvian city of Silves in 1189. At the time of his grandson, Afonso III of Portugal (1210 – 1279), the rest of the Algarve had finally been conquered, so "Ki ...

''o Bolonhês''), King of Portugal (5 May 121016 February 1279) was the first to use the title ''King of Portugal and the Algarve'', from 1249. He was the second son of King Afonso II of Portugal and his wife, Urraca of Castile; he succeeded his brother, King Sancho II of Portugal, who died on 4 January 1248. Early life Afonso was born in Coimbra. As the second son of King Afonso II of Portugal, he was not expected to inherit the throne, which was destined to go to his elder brother Sancho. He lived mostly in France, where he married Countess Matilda II of Boulogne in 1238, thereby becoming count of Boulogne, Mortain, Aumale and Dammartin-en-Goële ''jure uxoris''. Reign In 1246, conflicts between his brother, the king, and the church became unbearable. In 1247, Pope Inno ...

Ostrava
Ostrava (; pl, Ostrawa; german: Ostrau ) is a city in the north-east of the Czech Republic, and the capital of the Moravian-Silesian Region. It has about 280,000 inhabitants. It lies from the border with Poland, at the confluences of four rivers: Oder, Opava, Ostravice and Lučina. Ostrava is the third largest city in the Czech Republic in terms of both population and area, the second largest city in the region of Moravia, and the largest city in the historical land of Czech Silesia.
