forests, the largest of which, Morfe Forest, at its origin extended at least 8 miles in length and 6 miles in width, and became a favorite hunting-ground of the English Kings. The forest of Wrekin, or 'Mount Gilbert' as it was then called, covered the whole of that hill and extended eastward as far as Sheriffhales. Other forests were Stiperstones, the jurisdiction of which was from time immemorial annexed to the Barony of Caus, Wyre, Shirlot, Clee, Long Forest and Brewood. Welsh Marches The early political history of Shropshire is largely concerned with the constant incursions and depredations of the Welsh from across the border. Various statutory measures to keep the Welsh in check were enforced in the 14th and 15th centuries. In 1379 Welshmen were forbidden to purchase land in the county save on certain conditions, and this enactment was reinforced in 1400. In 1379 the men of Shropshire forwarded to parliament a complaint of the felonies committed by the men of Cheshire and of the Welsh marches, and declared the gaol of Shrewsbury Castle to be in such a ruinous condition that they had no place of imprisonment for the offenders when captured. In 1442 and again as late as 1535 acts were passed for the protection of Shropshire against the Welsh. Medieval national affairs Apart from the border warfare in which they were constantly engaged, the great Shropshire lords were actively concerned in the more national struggles. Shrewsbury Castle was garrisoned for the empress Maud by William Fitz-Alan in 1138, but was captured by King Stephen in the same year. Holgate Castle was taken by King John from Thomas Mauduit, one of the rebellious barons. Ludlow and Shrewsbury were both held for a time by Simon de Montfort. At Acton Burnell in 1283 was held the parliament which passed the famous Statute of Acton Burnell, and a parliament was summoned to meet at Shrewsbury in 1398. During the Percy rebellion Shrewsbury was in 1403 the site of a battle between the Lancastrian Henry IV, and Henry Percy ('Harry Hotspur') of Northumberland. The Battle of Shrewsbury was fought on 21 July 1403, at what is now Battlefield, just to the north of present-day Shrewsbury town. The battle resulted in the death of Henry Percy, and a victory to King Henry IV, who established a chapel at the site to commemorate the fallen. Religious foundations Among the Norman religious
