 All the magnates of England and Normandy were required to declare fealty to Matilda as Henry's heir, but when Henry I died in 1135, Stephen rushed to England and had himself crowned before either Theobald or Matilda could react.The Norman barons accepted Stephen as Duke of Normandy, and Theobald contented himself with his possessions in France.Matilda, though, was less sanguine, and secured the support of the Scottish king, David, who was her maternal uncle, and in 1138 also the support of her half-brother, Robert, Earl of Gloucester, an illegitimate son of Henry I.
