The Marches were the border
lands between England
. Since Norman
times these troublesome areas had been placed under the control of "Marcher Lords". These Lords had a long tradition of independence
, and they came to be seen as a considerable threat to English Kings in the 15th
century. The Marcher Lords provided England with help in defence in return for their privileges.
The powers of the Welsh Marcher Lords were eventually curbed with The Act of Welsh Union with England (1536 and 1543).
