Empress Matilda, a key figure in English medieval history, has long been remembered primarily for her dramatic escape from Oxford Castle in 1142 during the civil war known as The Anarchy. According to popular accounts, Matilda, besieged by her cousin and rival Stephen of Blois, fled the castle under cover of a heavy snowfall by descending from a window using a rope, crossing a frozen river while wearing white cloaks for camouflage, and eventually reaching the safety of Wallingford Castle. However, a new biography by Professor Elisabeth van Houts of the University of Cambridge offers a more measured account, suggesting the escape was likely less theatrical and more pragmatic, involving a discreet departure through a little-used gate during a moment of lax guard.

Born in 1102 to King Henry I of England and Matilda of Scotland, Empress Matilda was betrothed at the age of eight to Henry V, Holy Roman Emperor, who was nearly two decades her senior. Their marriage in 1114 elevated her status as empress and a significant political figure in Germany until Henry V’s death in 1125. Following his demise, Matilda returned to England, where her father arranged her marriage to Geoffrey of Anjou, a teenage nobleman. Henry I designated Matilda as his successor after the death of his only legitimate son in 1120, compelling the English nobility to swear allegiance to her.

Despite this, upon Henry’s death in 1135, Stephen of Blois quickly seized the throne, leading to a protracted conflict between the two claimants that spanned more than a decade. This period, characterized by widespread instability and described contemporaneously as a time when "Christ and all his saints slept," involved fierce military campaigns between the supporters of Stephen and Matilda.

The civil strife concluded with the Treaty of Westminster in 1153, in which Stephen acknowledged Matilda’s son as his heir. Following Stephen’s death in 1154, her son ascended to the throne as King Henry II. Matilda subsequently withdrew to Normandy, where she lived until her death in 1167.

Contemporary writers often depicted Matilda as imperious and haughty, traits which modern scholarship attributes to the gender biases of medieval chroniclers. Professor van Houts’ biography portrays her instead as a determined, intelligent, and resourceful leader. This new work aims to provide a balanced and comprehensive perspective on Empress Matilda, refining the historical narrative that has been shaped by legend and partial accounts. It is poised to become a definitive resource on her life for both scholars and general readers alike.
