Henry tackled all of the domestic policies together and gradually built on them a wider policy. From the first, he made it clear that he would rule England as the head of a united nation. He let past differences be forgotten –the late Richard II was honourably re-interred; the young Edmund Mortimer, 5th Earl of March, was taken into favour; the heirs of those who had suffered under the last reign were restored gradually to their titles and estates. Yet, where Henry saw a grave domestic danger, he acted firmly and ruthlessly, such as the Lollard discontent in January 1414 and including the execution by burning of Henry's old friend Sir John Oldcastle in 1417 to "nip the movement in the bud" and make his own position as ruler secure.
