Philip, the eldest of Charles's younger brothers, had become bishop of Beauvais in 1356,[2] and so their mother obtained permission from King John II of France to divide the counties between the remaining brothers, Peter and Robert. Peter received Alençon, and became Count of Alençon, while Perche was assigned to Robert, who became Count of Perche.[4]
Robert established his court at Nogent-le-Rotrou, a fortified town about 10 miles (16 km) south of Bellême and the county capital of Perche.[5]
On 5 April 1374, at the age of 30, Robert married Joan of Rohan (d. aft. 20 January 1407), the daughter of John I (Jean I), viscount of Rohan (1324–1396), and his wife, Joan, Princess of Navarre (1339–1409), the daughter of Philip III, King of Navarre and Joan II of Navarre.[6] They had one son, Charles (1375–1377), who did not survive his father.
^Jager lists the year of Robert's inheritance as 1367, but Siguret lists it as 1361.
