Richard I was King of England from 1189 until his death in 1199. He also ruled as Duke of Normandy, Aquitaine and Gascony; Lord of Cyprus; Count of Poitiers, Anjou, Maine, and Nantes; and was overlord of Brittany at various times during the same period. He was the third of five sons of Henry II of England and Eleanor of Aquitaine and seemed unlikely to become king, but his two elder brothers predeceased their father. Richard is known as Richard Cœur de Lion or Richard the Lionheart because of his reputation as a great military leader and warrior. The troubadour Bertran de Born also called him Richard Oc-e-Non, possibly from a reputation for terseness.

<span class="mw-page-title-main">Siege of Acre (1189–1191)</span> Battle of the Third Crusade

The siege of Acre was the first significant counterattack by Guy of Jerusalem against Saladin, leader of the Muslims in Syria and Egypt. This pivotal siege formed part of what later became known as the Third Crusade. The siege lasted from August 1189 until July 1191, in which time the city's coastal position meant the attacking Latin force were unable to fully invest the city and Saladin was unable to fully relieve it with both sides receiving supplies and resources by sea. Finally, it was a key victory for the Crusaders and a serious setback for Saladin's ambition to destroy the Crusader states.

<span class="mw-page-title-main">Crusades</span> Religious wars of the High Middle Ages

The Crusades were a series of religious wars initiated, supported, and sometimes directed by the Christian Latin Church in the medieval period. The best known of these military expeditions are those to the Holy Land in the period between 1095 and 1291 that were intended to conquer Jerusalem and its surrounding area from Muslim rule. Beginning with the First Crusade, which resulted in the conquest of Jerusalem in 1099, dozens of military campaigns were organised, providing a focal point of European history for centuries. Crusading declined rapidly after the 15th century.

The Crusade of 1197, also known as the Crusade of Henry VI or the German Crusade, was a crusade launched by the Hohenstaufen emperor Henry VI in response to the aborted attempt of his father, Emperor Frederick I, during the Third Crusade in 1189–90. Thus the military campaign is also known as the "Emperor's Crusade".

<span class="mw-page-title-main">Garnier de Nablus</span> Grand Master of the Knights Hospitaller

He fought at the Battle of Arsuf in 1191 during the Third Crusade. It was under his magistracy that the headquarters of the Order were transferred from Tyre to Acre. He was succeeded by Geoffroy de Donjon.

His paternal grandparents were Erard I, Count of Brienne and Alix de Roucy.

Rotrou IV (1135-1191), was the Count of Perche. He joined Louis VII of France in a war against Henry II of England, in which he lost lands to the English. Rotrou later went on crusade with Philip II of France and died after the Siege of Acre in 1191.

<span class="mw-page-title-main">Armengol de Aspa</span> Catholic military knight and leader

Armengol de Aspa, also known as Hermangard d'Asp, was the ninth Grand Master of the Knights Hospitaller, holding the office from 1188 until his resignation in 1189 or 1190. He succeeded William Borrel who was interim Grand Master. It was under his magistracy that the headquarters of the Order was transferred from Jerusalem to Tyre. It was probably during the winter of 1189 or 1190 that Armengol's magistracy ceased, but this was not due to his death, since he appears again as lord of Amposta from December 1190 to April 1191. We have no information on what this first abdication in the history of the Order was, but he was succeeded by Garnier de Nablus sometime in 1190.

The Almohad Caliphate launched a major offensive against the Kingdom of Portugal in the spring of 1190 that lasted into the summer of 1191. The Caliph Yaʿqūb al-Manṣūr crossed over from Africa to take personal command of his forces. The campaign of 1190 was underwhelming because of assistance Portugal received from passing armies of the Third Crusade. The sieges of Tomar, Santarém and Silves had to be abandoned, but the caliph overwintered in Seville. The campaign of 1191 reversed Portugal's recent reconquistas (reconquests), captured Silves after a second siege and pushed the frontier north to the Tagus.

<span class="mw-page-title-main">Siege of Silves (1189)</span>

The siege of Silves was an action of the Third Crusade and the Portuguese Reconquista in 1189. The city of Silves in the Almohad Caliphate was besieged from 21 July until 3 September by the forces of Portugal and a group of crusaders from northern Europe on their way to the siege of Acre. The defenders capitulated on terms, the city was handed over to Portugal and the crusaders took a portion of the spoils.
