The government of theKingdom of England in theMiddle Ages was amonarchy based on the principles offeudalism. Theking possessed ultimate executive, legislative, and judicial power. However, some limits to the king's authority had been imposed by the 13th century.Magna Carta established the principle that taxes could not be levied without common consent, andParliament was able to assert its power over taxation throughout this period.

Under thePlantagenets, rules ofprimogeniture were established, and a new reign was considered to have begun on the death of the old king. WhenHenry III died in 1272, his sonEdward I became king even though he was on acrusade at the time and would not be crowned until 1274.[1]
Henry III was crowned twice. The nine-year-old Henry was first given a hasty coronation in 1216 atGloucester Cathedral byGuala Bicchieri, thepapal legate. In a second coronation at Westminster Abbey, the king was crowned by the Archbishop of Canterbury as was customary.[2]
Edward II was not crowned until February 1308, seven months after his accession. Edward III was crowned quickly out of necessity due to his accession after the deposition of his father. Edward II was deposed on 20 January 1327 and his son was crowned on 1 February.[1]
At the coronation, the new king swore an oath. The precise wording is unknown before 1308. The king probably swore to uphold the laws of King Edward the Confessor, to work for the peace of the church and the people, and to prevent rapacity and oppression. Both Henry III and Edward I additionally promised to preserve and recover the rights of the Crown. Edward II added the clause promising "to maintain and preserve the laws and rightful customs which the community of your realm shall have chosen".[1]
As a feudal overlord, the king had various rights overtenants-in-chief (or feudal barons) including the rights:[3]
Unlike other lords, kings were anointed and had greater power. The Crown alone:[4][5]
The king carried with him a special jurisdiction called theverge, which was the 12 mile area around the king's person where local courts did not have authority to hear cases. Only the courts of the royal household had jurisdiction.[6]
TheRoman law principle of necessity was also an important component of the Crown's powers. If the king could demonstrate an urgent necessity, his subjects were obliged to assist him. In 1294, Edward I justifiedhis seizure of wool based on the "certain and urgent necessity" that existed.Edward III also requested taxation on the basis of the necessity of defending the realm.[7]
Royal authority was challenged.Henry de Bracton argued that the king was under the law, and if he went beyond the law he should be "bridled" by his earls and barons.[7]
In the 13th century, the distinction between the king and the Crown developed. In the reign of Henry III, there are some indications that the Crown was regarded as distinct from the king in terms of the alienation of royal land.[8] By the reign of Edward III, this distinction was well developed. TheCrown Estate belonged to the Crown and should not be alienated by individual kings.[4]
During the reign ofEdward II, theearl of Lincoln presented theDeclaration of 1308 arguing that homage and allegiance were due more to the Crown than to the person of the king(seeDoctrine of capacities).[9] One of the arguments fordeposing Edward II was that he had not defended the rights of the Crown, specifically that he failed to preserve royal lands and had taken evil counsel.[6]
The king's council provided the monarch with expert advice and assistance in governing the kingdom. It was involved in legal, financial, and diplomatic business. It heard important legal cases, and it could reach decisions without reference to thecommon law.[10] It could draft legislation in the form of administrative orders issued asletters patent orletters close.[11]
Members included the king's ministers and closest advisers, such as judges, thechancellor, and thetreasurer. Members took an oath to give the king faithful counsel. The council met in theStar Chamber at Westminster Palace.[10]

In the Middle Ages, there was no clear distinction between the royal court and the royal household. The court might refer to everyone around the king, while the household referred to the specific institution that served the king.[12]
There were around 500 members of the household. The most important department was thewardrobe. It managed the household's finances and oversaw war spending. It was led by thekeeper of the wardrobe, who was one of the king's most important ministers. The wardrobe controlled theprivy seal, which was used to issue orders to the chancery and exchequer. Under Edward II, this writing office was separated from the wardrobe, and the king began using thesecret seal when issuing orders to thekeeper of the privy seal.[13]
The military household includedbannerets,knights,squires, andsergeants-at-arms. In addition to a military role, they also served as administrators and diplomats.[12]

The main financial department was theexchequer. The exchequer developed under Henry I (r. 1100–1135) and audited the accounts of sheriffs and other royal officials.[14] At the end of the 12th century, it moved from Winchester to a chamber adjacent toWestminster Hall.[15] The lower exchequer received payments and issued receipts in the form oftally sticks. The upper exchequer was a court called theExchequer of Pleas.[16]
In theory, the exchequer controlled government finances. All royal revenue was supposed to be paid to the exchequer, and its officers (thetreasurer andexchequer chamberlains) would pay out funds as needed to the royal household. In reality, there were periods, such as in the reign of Edward I, where the wardrobe was outside of the exchequer's control. Household officials often diverted royal revenue before it ever reached the exchequer, and the wardrobe did not always submit its accounts to be audited.[17]
Thechancellor oversaw thechancery or government writing office. It was originally part of the royal chapel. The clerks in the chapel served both the king's spiritual and secretarial needs.[18] During Edward I's reign, the chancery clerks started to stay in England rather than accompany the king on foreign military expeditions. By the reign of Edward III, it was permanently based at Westminster.[19]
In 1324, there were about a hundred clerks who produced around 29,000 writs. At the head of the chancery's organization were 12 master clerks who were termed "first form" clerks. Beneath them were 12 second form clerks. Beneath them were the 24 cursitors who wrote the standardized writs. Below these were assistant clerks and servants.[19]
Government administration could be needlessly complicated. In the 14th century, a royal order could be issued originally under the king's secret seal, then sent to the privy seal office which would instruct the chancery to prepare the final writ. "Three documents were used where one would have sufficed. This might lead to long delays."[20]
Parliament evolved out of themagnum concilium and met occasionally when summoned by the king.[21] Parliament differed from the older great council by being "an institution of the community rather than the crown". For the community of the realm, "it acts as representative, approaching the government from without, and 'parleying' with the king and his council".[22]
Before 1258, legislation was not a major part of parliamentary business.[11] It is in the reign of Edward I that Parliament passed the first major statutes. "However, they were notmade by theKing in Parliament, but simply announced by the king or his ministers in a parliament" [emphasis in original].[23] The actual work of law-making was done by the king and his council.[24] Completed legislation was then presented to Parliament for ratification.[25]
Parliament successfully asserted for itself the right to consent to taxation, and a pattern developed in which the king would make concessions (such as reaffirming Magna Carta) in return for grants of taxation.[26] This was its main tool in disputes with the king. Nevertheless, this proved ineffective at restraining the king as he was still able to raise lesser amounts of revenue from sources that did not require parliamentary consent:[27][28]
England was divided into 39counties, which existed with only minor boundary changes until 1974 when theLocal Government Act 1972 went into effect.[29]
The most important county officer was thesheriff. Sheriffs were appointed by the king and served at his pleasure. He presided over the county court, collected taxes, and paid the county farm owed to the king.[30] As the main communication channel between the Crown and the counties, the sheriff was responsible for sharing royal proclamations. He was assisted by an under-sheriff, clerks,bailiffs, and sub-bailiffs. One clerk was responsible for county finances, and another was responsible for recording writs received and actions taken.[31] Henry III preferred to appoint local knights to the office, and this trend continued after his reign.[32]
The king appointed anescheator for counties north of the Trent and another for those counties south of it. These appointed sub-escheators in each county to enforce royal wardship rights and manage lands that escheated to the Crown.[33]
The king was the fount of justice.[35] Initially, important cases were heardcoram rege (Latin for "in the presence of the king") with the advice of hiscuria regis. But the growth of the legal system required specialization, and the judicial functions of thecuria regis were delegated to two courts sitting atWestminster Hall.[36]
TheCourt of Common Pleas split from the Exchequer of Pleas in the 1190s. It had jurisdiction over civil cases (such as debts, property rights, and trespass). It was staffed by achief justice of the Common Pleas and several otherjustices of the Common Pleas.[37][38]
In the 1230s, the earliercoram rege court developed into theCourt of King's Bench.[38] It originally traveled with the king but was permanently based at Westminster Hall by the 1300s. Cases came before the King's Bench as appeals from lower courts (including Common Pleas) bywrits of error. It had jurisdiction over civil matters involving the king and criminal cases. It was staffed by thechief justice of the King's Bench and severaljustices of the King's Bench.[37][39]
