Continental and Welsh politics, 1108–1114 Normandy faced an increased threat from France,
Anjou and
Flanders after 1108. Louis VI succeeded to the French throne in 1108 and began to reassert central royal power. Henry refused, and Louis responded by mobilising an army. After some arguments, the two kings negotiated a truce and retreated without fighting, leaving the underlying issues unresolved. He inherited the
county of Maine, but refused to recognise Henry as his feudal lord and instead allied himself with Louis.
Robert II of Flanders also briefly joined the alliance, before his death in 1111. of Henry's rival,
Louis VI of France In 1108, Henry betrothed his six-year-old daughter Matilda to
Henry V of Germany. For the English king, this was a prestigious match; for Henry V, it was an opportunity to restore his financial situation and fund an expedition to Italy, as he received a dowry of £6,666 from England and Normandy. Raising this money proved challenging, and required the implementation of a special "aid", or tax, in England. Matilda was crowned
German queen in 1110. Henry responded to the French and Angevin threat by expanding his own network of supporters beyond the Norman borders. Some Norman barons deemed unreliable were arrested or dispossessed, and Henry used their forfeited estates to bribe his potential allies in the neighbouring territories, in particular Maine. Around 1110, Henry attempted to arrest the young William Clito, but William's mentors moved him to the safety of Flanders before he could be taken. At about this time, Henry probably began to style himself as the duke of Normandy. Robert of Bellême turned against Henry once again, and when he appeared at Henry's court in 1112 in a new role as a French ambassador, he was arrested and imprisoned. Rebellions broke out in France and Anjou between 1111 and 1113, and Henry crossed into Normandy to support his nephew
Theobald IV, Count of Blois, who had sided against Louis in the uprising. In a bid to isolate Louis diplomatically, Henry created alliances with Anjou and
Brittany by betrothing his young son, William Adelin, to Fulk of Anjou's daughter
Matilda and marrying his illegitimate daughter
Matilda to
Conan III, Duke of Brittany. Louis backed down and in March 1113 met with Henry near Gisors to agree a peace settlement, giving Henry the disputed fortresses and confirming Henry's overlordship of Maine,
Bellême and Brittany. Meanwhile, the situation in Wales was deteriorating. Henry had conducted a campaign in South Wales in 1108, pushing out royal power in the region and colonising the area around Pembroke with Flemings. By 1114, some of the resident Norman lords were under attack, while in Mid-Wales,
Owain ap Cadwgan blinded one of the political hostages he was holding, and in
North Wales Gruffudd ap Cynan threatened the power of the
Earl of Chester. Henry sent three armies into Wales that year, with
Gilbert Fitz Richard leading a force from the south,
Alexander I of Scotland pressing from the north and Henry himself advancing into Mid-Wales. He reinforced the Welsh Marches with his own appointees, strengthening the border territories.
Rebellion, 1115–1120 of Henry I, struck at the
Oxford mint Concerned about the succession, Henry sought to persuade Louis VI to accept his son, William Adelin, as the legitimate future Duke of Normandy, in exchange for his son's homage. Henry crossed into Normandy in 1115 and assembled the Norman barons to swear loyalty; he also almost successfully negotiated a settlement with Louis, affirming William's right to the Duchy in exchange for a large sum of money. Louis, backed by his ally
Baldwin VII of Flanders, instead declared that he considered William Clito the legitimate heir to the Duchy. War broke out after Henry returned to Normandy with an army to support Theobald of Blois, who was under attack from Louis. Henry and Louis raided each other's towns along the border, and a wider conflict then broke out, probably in 1116.
Amaury III of Montfort and many other barons rose up against Henry, and there was an assassination plot from within his own household. Henry responded by mounting campaigns against the rebel barons and deepening his alliance with Theobald. Baldwin of Flanders was wounded in battle and died in September 1118, easing the pressure on Normandy from the north-east. Henry attempted to crush a revolt in the city of
Alençon, but was defeated by Fulk and the Angevin army. Forced to retreat from Alençon, Henry's position deteriorated alarmingly, as his resources became overstretched and more barons abandoned his cause. Early in 1119, Henry's daughter Juliane and son-in-law Eustace of Breteuil threatened to join the baronial revolt. Hostages were exchanged in a bid to avoid conflict, but relations broke down and both sides mutilated their captives. In the aftermath, Henry dispossessed the couple of almost all of their lands in Normandy. Henry's situation improved in May 1119 when he enticed Fulk to switch sides by finally agreeing to marry William Adelin to Fulk's daughter Matilda and paying Fulk a large sum of money. Fulk left for the
Levant, leaving the County of Maine in Henry's care, and the King was free to focus on crushing his remaining enemies. During the summer Henry advanced into the Norman Vexin, where he encountered Louis's army, resulting in the
Battle of Brémule. Henry appears to have deployed scouts and then organised his troops into several carefully formed lines of dismounted knights. Unlike Henry's forces, the French knights remained mounted; they hastily charged the Anglo-Norman positions, breaking through the first rank of the defences but then becoming entangled in Henry's second line of knights. Surrounded, the French army began to collapse. Louis and William Clito escaped from the battle, leaving Henry to return to Rouen in triumph. The war slowly petered out after this battle, and Louis took the dispute over Normandy to
Pope Callixtus II's council in
Reims that October. Henry faced French complaints concerning his acquisition and subsequent management of Normandy, and despite being defended by
Geoffrey, the Archbishop of Rouen, Henry's case was shouted down by the pro-French elements of the council. Callixtus declined to support Louis, and merely advised the two rulers to seek peace. Amaury de Montfort came to terms with Henry, but Henry and William Clito failed to find a mutually satisfactory compromise. In June 1120, Henry and Louis formally made peace on terms advantageous to the English king: William Adelin gave homage to Louis, and in return Louis confirmed William's rights to the Duchy.
Succession crisis, 1120–1124 '' at
Barfleur on 25 November 1120 Henry's succession plans were thrown into chaos by the sinking of the
White Ship off the French coast on 25 November 1120. Henry had left the port of
Barfleur for England in the early evening, leaving William Adelin and many of the younger members of the court to follow on that night in a separate vessel, the
White Ship. Both the crew and passengers were drunk and, just outside the harbour, the ship hit a submerged rock. The ship sank, killing as many as 300 people, with only one survivor, a butcher from Rouen. The disaster left Henry with no legitimate son, his nephews now the closest possible male heirs. Henry announced he would take a new wife,
Adeliza of Louvain, opening up the prospect of a new royal son, and the two were married at
Windsor Castle in January 1121. Henry appears to have chosen her because she was attractive and came from a prestigious noble line. Adeliza seems to have been fond of Henry and joined him in his travels, probably to maximise the chances of her conceiving a child. The
White Ship disaster initiated fresh conflict in Wales, where the drowning of Richard, Earl of Chester, encouraged a rebellion led by
Maredudd ap Bleddyn. Henry intervened in North Wales that summer with an army and, although he was hit by a Welsh arrow, the campaign reaffirmed royal power across the region. Fulk returned from the Levant and demanded that Henry return Matilda and her dowry, a range of estates and fortifications in Maine. Fulk married his daughter
Sibylla to William Clito, and granted them Maine. Once again, conflict broke out, as Amaury de Montfort allied himself with Fulk and led a revolt along the Norman-Anjou border in 1123. Henry dispatched his illegitimate son
Robert of Gloucester and
Ranulf le Meschin to Normandy and then intervened himself in late 1123. He began the process of besieging the rebel castles, before wintering in the Duchy. In the spring of 1124, campaigning began again. In the
Battle of Bourgthéroulde, fought near
Rouen, Borleng, castellan of
Bernay, Eure, led the King's army and received intelligence that the rebels were departing from the rebel base in
Beaumont-le-Roger allowing him to ambush them as they traversed through the
Brotonne forest. Waleran charged the royal forces, but his knights were cut down by Odo's archers and the rebels were quickly overwhelmed. Waleran was captured, but Amaury escaped. He paid Pope Callixtus a large amount of money, in exchange for the Papacy annulling the marriage of William Clito and Sibylla on the grounds of
consanguinity.
Planning the succession, 1125–1134 Henry and Adeliza did not conceive any children, generating prurient speculation as to the possible explanation, and the future of the dynasty appeared at risk. Henry may have begun to look among his nephews for a possible heir. He may have considered
Stephen of Blois as a possible option and, perhaps in preparation for this, he arranged a beneficial marriage for Stephen to the wealthy heiress
Matilda of Boulogne. Theobald of Blois, his close ally, may have also felt that he was in favour with Henry. William Clito, who was Louis VI's preferred choice, remained opposed to Henry and was therefore unsuitable. Henry may have also considered his own illegitimate son, Robert of Gloucester, as a possible candidate, but English tradition and custom would have looked unfavourably on this. Henry's plans shifted when his son-in-law, Holy Roman Emperor Henry V, died in 1125. The King recalled his widowed daughter, Empress Matilda, to England the next year and declared that, should he die without a male heir, she was to be his rightful successor. The Anglo-Norman barons were gathered together at Westminster at Christmas 1126, where they swore to recognise Matilda and any future legitimate heir she might have. Fresh conflict broke out in 1127, when the childless
Charles I, Count of Flanders, was murdered, creating a local succession crisis. With Louis's support, the Flemings chose William Clito to become their new ruler. This development potentially threatened Normandy, and Henry began to finance a
proxy war in Flanders, promoting the claims of William's Flemish rivals. In an effort to disrupt the French alliance with William, Henry mounted an attack into France in 1128, forcing Louis to cut his aid to William. William died unexpectedly in July, removing the last major challenger to Henry's rule and bringing the war in Flanders to a halt. Without William, the baronial opposition in Normandy lacked a leader. A fresh peace was made with France, and Henry was finally able to release the remaining prisoners from the revolt of 1123, including Waleran of Meulan, who was rehabilitated into the royal court. Meanwhile, Henry rebuilt his alliance with Fulk of Anjou, this time by marrying Matilda to Fulk's eldest son, Geoffrey. The pair were betrothed in 1127 and married the following year. It is unknown whether Henry intended Geoffrey to have any future claim on England or Normandy, and he was probably keeping his son-in-law's status deliberately uncertain. Similarly, although Matilda was granted several castles in Normandy as part of her dowry, it was not specified when the couple would actually take possession of them. Fulk left Anjou for
Jerusalem in 1129, declaring Geoffrey the Count of Anjou and Maine. The marriage proved difficult, as the couple did not particularly like each other and the disputed castles proved a point of contention, resulting in Matilda returning to Normandy later that year. Henry appears to have blamed Geoffrey for the separation, but in 1131 the couple were reconciled. Much to the pleasure and relief of Henry, Matilda then gave birth to two sons,
Henry and
Geoffrey, in 1133 and 1134. == Death and legacy ==
