 In May 1490 Arthur was created warden of all the marches towards Scotland and the Earl of Surrey was appointed as the Prince 's deputy . From 1491 , Arthur was named on peace commissions . In October 1492 , when his father travelled to France , he was named Keeper of England and King 's Lieutenant . Following the example of Edward IV , Henry VII set up the Council of Wales and the Marches for Arthur in Wales , in order to enforce royal authority there . Although the council had already been set up in 1490 , it was headed by Jasper Tudor , Duke of Bedford . Arthur was first dispatched to Wales in 1501 , at the age of fifteen . In March 1493 , Arthur was granted the power to appoint justices of oyer and terminer and inquire into franchises , thus strengthening the council 's authority . In November of that year , the Prince also received an extensive land grant in Wales , including the County of March .
