Under this Duke, Lancaster Castle was partly rebuilt, and a considerable portion of the gateway tower (which still bears his name) added.

Henry Bolingbroke, who was now Duke of Hereford, was the next heir to the dukedom, but as he was in exile for his supposed treason, the King (Richard II.) seized the possessions of the late John of Gaunt, and shortly afterwards proceeded to Ireland, where he learnt that during his absence Bolingbroke had returned to England, and that the whole kingdom had received him with open arms. The King’s flight to Wales, his surrender, first of his person and then of his throne, followed in rapid succession, and on September 29, 1399, the head of the House of Lancaster became King of England under the title of Henry IV.

It must be remembered that the County Palatine and Duchy of Lancaster are not identical, as the latter comprises many places which are not in Lancashire, but are scattered over fourteen counties in England and Wales. The Duchy of Lancaster was held by Henry IV. as heir to his father, but his right to the Crown of England was by no means of such an indefeasible character. To remedy this defect, the King obtained several Acts of Parliament, declaring that neither the inheritance of his Duchy of Lancaster nor its liberties should be affected in consequence of his having assumed the royal dignity; also that all ecclesiastical benefices in the county should be conferred by himself or his heirs; that the right of succession to the duchy after his death should belong to his eldest son, Henry, Prince of Wales, and his heirs, or, in default of such heirs, to his second son, Thomas.[90] He also established the duchy court of Lancaster, which was held at Westminster.[91] The county also held its Star Chamber, the decrees of which were certainly not in accordance with the provisions of Magna Charta. This court, with others of the same character, was abolished in 1640–41 by Act of Parliament. Henry V., who succeeded to the dukedom, confirmed all that his father had done respecting the duchy. Henry VI., being pressed for money, mortgaged the revenues of his duchies of Lancaster and Cornwall for a term of five years, and on their reverting to the Crown in 1460–61, several new officers were appointed—amongst others, a chancellor, a receiver–general, an attorney–general for the duchy, and one for the county palatine.[92]

In 1461 Edward IV. obtained an Act of Parliament “for incorporating and also for confiscating the Duchy of Lancaster to the Crown of England for ever,” and since then the ruling monarch has held the duchy with all its liberties and privileges. In the time of Philip and Mary, in an Act for enlarging the duchy, it is styled “one of the most Princeliest and Stateliest peeces of our Sovereigne Ladie, the Queenes, auncyent inheritance.”

From the time of the creation of the palatinate, all justices of assize, of gaol–delivery, and of the peace, have been made under the seal of the county palatine, as are also the sheriffs for the county; an almost complete list of the latter from A.D. 1156 to the present time has been preserved.[93]

One of the privileges of a county palatine was that none of its inhabitants could be summoned out of their own county except for certain offences. This exemption, it appears, was not always observed, and its non–observance led to several serious riots, and resulted in the passing of an Act of Parliament in A.D. 1449, which declared that anyone making a distress where he had no “fee, seigniory or cause” in the Duchy of Lancaster should be treated as a felon. Another Act passed in 1453 directed that, if a person was outlawed in Lancashire, only his goods and lands in that county were to be forfeited; this law was, however, repealed two years afterwards.

The population of Lancashire shortly before the Black Death in 1349 was no doubt very much greater than it was for many years subsequently, notwithstanding the very heavy levies made upon it for the various wars in which the three Edwards were engaged. For the war in Wales, in 1282, the Sheriff of Lancashire was instructed to call upon every person owning land or rents worth £30 a year to provide a horse and armour and to join the royal forces; whilst William le Boteler, of Warrington, was ordered to meet the King at Worcester, and with the assistance of others he was to raise in Lancashire 1,000 strong and able men to serve in the Welsh war. Amongst the accounts of this campaign we find an entry referring to this: “To Master William le Boteler for the wages of one constable, two hundred and six archers, with ten captains of twenties, from Saturday, January 16 [1283], to Wednesday, the 27th of the same month, for twelve days, £22 4s.”[94]

The Crusaders also had many followers from this county, whilst for the wars with France and Scotland writ followed writ in quick succession, all calling for men and arms. And again in the fifteenth century the drain continued to be heavy, and culminated with the War of the Roses, which began in 1455. None of the battles between the Houses of York and Lancaster were fought within this county, but during the struggle Lancashire must have sent some of her bravest sons to perish in that ignoble strife between the roses red and white.

It should also be noted that in 1422 a second visitation of the plague appeared in the north of Lancashire, which, though not so widespread as it was in 1349, appears to have been quite as deadly, for on June 24, 1422, a precept was sent to the Sheriff to make proclamation in all the market towns and elsewhere within the county, that the sessions fixed to be held at Lancaster on Tuesday, the morrow of St. Lawrence, would be adjourned to Preston, because the King had heard both by vulgar report and the credible testimony of honest men, that in certain parts of Lancashire, and especially in the town of Lancaster, there was raging so great a mortality that a large portion of the people there, from the corrupt and pestiferous air, infected with divers infirmities and deadly diseases, were dying rapidly, and the survivors quitting the place from dread of death, so that in many cases the land remained untilled, and the most grievous desolation reigned where late was plenty.[95]

The Parliamentary representation of Lancashire began in the thirteenth century. Previous to this the King had three times a year called together his Council, consisting of the barons, the heads of the Church, and the military chief tenants of the Crown; but in 1213 King John directed the sheriffs of counties to send four men of each shire to confer with him on national affairs.[96] In 1254 the number was reduced to two for each county; in 1261 Henry III. summoned three, which was shortly afterwards again reduced to two. In 1265 Simon de Montford, Earl of Leicester, in the King’s name summoned to Westminster two knights from each shire and two burgesses from each town. The exact character of these meetings is unknown, as is the method of the selections of the knights of the shire; but in 1290 they were formally summoned to Parliament, and in 1294 became a necessary part of the national council chamber.
