The sheriffs of the English counties were ordered to send "knights of the shire" to attend a number of parliaments before 1265, but they were not required to have them chosen by election. No such summonses are known to have required the attendance of citizens of cities or burgesses of other boroughs. Records of this sort of summons survive for the Oxford Parliament, which was the seventh parliament of King Henry III, assembled 27 October 1258 and presumed dissolved when writs "de expensis" were issued on 4 November 1258, and for the same king's sixteenth parliament, summoned on 4 June 1264 and assembled on 22 June 1264, although the date of dissolution is unknown.
