 The Norman baron allegiance set the stage for a race between the heirs of William I, where the Duke of Normandy and the King of England sought to gain as much support from powerful and influential houses as possible against each other.Throughout the power struggle between Normandy and England in the early 1090s, Ranulph ended up switching sides and submitting to the Duke of Normandy.At the Welsh Marches in 1093, Ranulph joined Norman forces, leading with Earl Roger of Shrewsbury, Ralph Tosny of Clifford Castle and Philip de Braose of Radnor.
