During the disputes concerning the succession, on the death of the Conqueror, the Grentemaisnells seized Leicester castle, and held it for duke Robert. This subjected it to the fury of the successful partizans of William Rufus, and the castle lay for some time in a dismantled state. In the next reign it was granted by Henry to his favourite Robert first earl of Leicester, who repaired the damages and it became the principal place of residence of himself and the second earl, Robert Bossu. The third earl Robert surnamed Blanchmains, encreased his property and power, by his marriage with Petronilla, or Parnel, the heiress of the Grentemaisnells, but the violent temper of this earl involved him in disputes with king Henry the second, whose forces under the command of the Chief Justiciary, Richard de Lucy, took Leicester and its castle by assault, and reduced both to an almost uninhabited heap of ruins. Blanchmains regained however the favor of his king and was restored to his estates, but both he and his son, Robert Fitz-Parnel engaging in the crusades, the town of Leicester was but ill rebuilt, and the castle remained in a state of delapidation for many years. Fitz-Parnel dying without issue, the _honor_ of Leicester, as part of the Bellomont estates were called, passed into the family of Simon de Montfort, in consequence of his marriage with one of the sisters of Fitz-Parnels. But the Montfort earls of Leicester, both father and son, were too much engaged in the busy transactions of their times to pay much attention to their property at Leicester. After the death of the latter, in the Battle of Evesham, the Leicester property was conferred by Henry the third on his second son Edmond earl of Lancaster, whose second son Henry, heir and successor to Thomas earl of Lancaster, beheaded at Pontefract, in the year 1322 made Leicester his principal place of residence, and under him and the two next succeeding earls, the castle recovered and probably surpassed its former state of splendor.
