In the 13th century the development of law became a dominant concern, as is shown by the great treatise
Finance
Edward began his reign with heavy debts incurred on crusade, and his various wars also were costly. In 1275 Edward gained a secure financial basis when he negotiated a grant of export duties on wool, woolfells, and hides that brought in an average of £10,000 a year. He borrowed extensively from Italian bankers on the security of these customs revenues. The system of levying taxes on an assessment of the value of movable goods was also of great value. Successive profitable taxes were granted, mostly in Parliament. It was partly in return for one such tax, in 1290, that Edward expelled the Jews from England. Their moneylending activities had made them unpopular, and royal exploitation had so impoverished the Jews that there was no longer an advantage for Edward in keeping them in England.
The growth of Parliament
Edward fostered the concept of the community of the realm and the practice of calling representative knights of the shire and burgesses from the towns to Parliament. Representatives were needed to give consent to taxation, as well as to enhance communication between the king and his subjects. The process of petitioning the king and his council in Parliament was greatly encouraged. Historians have argued much about the nature of Edward’s Parliament, some seeing the dispensation of justice as the central element, others emphasizing the multifaceted character of an increasingly complex institution. Some see Edward as responding to the dictates of Roman law, while others interpret the development of Parliament in terms of the practical solution of financial and political problems. Historians used to refer to the 1295 assembly as the Model Parliament because it contained all the elements later associated with the word parliament, but in fact these can all be found earlier. The writs to the sheriffs asking them to call knights and burgesses did, however, reach a more or less final form in 1295. They were to be summoned “with full and sufficient authority on behalf of themselves and the community . . . to do whatever shall be ordained by common counsel.” Representatives of the lower clergy were also summoned. This Parliament was fully representative of local communities and of the whole community of the realm, but many Parliaments were attended solely by the magnates with no representatives present.
Edward’s wars
In the first half of his reign Edward was thoroughly successful in Wales. Llywelyn ap Gruffudd, prince of Gwynedd, had taken advantage of the Barons’ War to try to expand his authority throughout Wales. He refused to do homage to Edward, and in 1277 the English king conducted a short and methodical campaign against him. Using a partly feudal, partly paid army, the core of which was provided by the royal household knights, and a fleet from the Cinque Ports, Edward won a quick victory and exacted from Llywelyn the Treaty of Conway. Llywelyn agreed to perform fealty and homage, to pay a large indemnity (from which he was soon excused), and to surrender certain districts of North Wales. There was considerable Welsh resentment after 1277 at the manner in which Edward imposed his jurisdiction in Wales.
