Wales had been an unruly area during the Wars of the Roses due to no rule from London.
Edward IV had established the Council of Wales and the Marches in 1472, there was still no attempt at creating a single system of counties and lordships, or abolish privileges of Marcher lords.
Henry revived the Council in 1493 and put it under the nominal head of Arthur.
The king used his Welsh connections and the death and loss of lands by many Marcher Lords (whom had been killed in the War of the Roses) to increase control in Wales.
