The Cottesbrokes took their name from a Northamptonshire village where a Robert Cottesbroke of London, almost certainly a relative, held property before his death in 1393. William may even have been descended from David de Cotesbroke†, who in 1311, at the height of the popular movement for reform of London’s government, was appointed comptroller of the City chamber.
During the early part of his career Cottesbroke devoted much of his time to the development of his business and trading activities. From an early stage he seems to have ben buying and selling a wide range of goods, not necessarily just those which were traditionally retailed by grocers. In March 1417 a dispute between him and two other men was submitted by the mayor to the wardens of the Haberdashers, suggesting that the dispute centred on dealings which Cottesbroke had with members of that craft.
By the end of the decade there is clear evidence that Cottesbroke was becoming a successful and respected overseas trader. In November 1438 he and John Bale, a prominent tailor and fellow merchant, gave their judgement in a dispute between a Genoese merchant, Geronimo Centurione, and a grocer, John Alkerich, which centred upon a transaction involving casks of Seville oil.
Cottesbroke’s career had not always been so charmed. At some point in the first half of the 1420s, he and four other London merchants, including the prominent mercer John Coventry and the draper William Weston†, were accused of treason by one John Newman. The details of their purported offence are unknown, and with the aid of the chancellor, Bishop Beaufort, they succeeded in bringing the matter before the Parliament of 1425 and clearing their names.
In the meantime Cottesbroke became involved in another trade-related dispute and in the summer of 1441 he brought a suit against Peter Pope, a London barber, whom he accused of forcibly removing merchandise belonging to him in the parish of St. Dunstan in the East. The goods comprised 54 bars of ‘long iron’ and 47 pieces of ‘short iron’ and were said to be worth £22. In his bill, put up before the barons of the Exchequer on 26 Jan. 1442 (the day after the assembling of the Parliament in which he represented London), Cottesbroke alleged that the theft had taken place on the previous 18 Nov. and that Pope had kept the goods until 16 Jan. In his defence Pope argued that the goods had been brought into the port of London on 7 Nov. in the ship of one Richard Scot, but that Cottesbroke had failed to pay the customs duty on them.
It was not until the 1440s that Cottesbroke first began to make his mark upon London’s political and civic life. In February 1441 he was appointed to a committee of the common council, while in September that year he was one of the ‘notable and trustworthy citizens’ who were present at St. Martin le Grand for the examination of a citizen accused of forging another man’s seal.
Despite this it is almost certain that Cottesbroke had already established connexions with some of those who spearheaded the growing movement for political reform in the capital. This had been born out of a jurisdictional dispute between the Tailors and Drapers which developed into a wider ‘constitutional’ debate about the participation in elections of all citizens, rather than just those summoned by the mayor. The champion of the radical cause was Ralph Holland, a tailor alderman, whose candidacy for the mayoralty was rejected on three occasions, much to the resentment of his followers among the city’s artisans. Disturbances broke out in October 1441 following Holland’s third failure, and a number of skinners and tailors were put in prison. Over the course of the next two years the City put in place measures to prevent further trouble from occurring, including the obtaining of a royal writ which specifically allowed the mayor and sheriffs to select those who were to attend the mayor’s election. Discontent nevertheless continued to manifest itself, particularly after the establishment of a new peace commission for London in the spring of 1443, which was subsequently incorporated into a new charter granted to the City in the following year: this formalized the judicial powers of the mayor and aldermen, so that they were no longer merely guardians of the peace, but justices with powers to hear and determine cases. As one chronicler stated, ‘a commission was sued for the City of London which was called a charter, and the commons were greatly aggrieved therewith’. It was at the election of the sheriffs and chamberlain on 21 Sept. that trouble once again flared up, a few days after Holland himself had attacked the commission in the court of aldermen. According to contemporary reports a great number of ‘inferior’ citizens, who had not been summoned, gained entrance to the Guildhall. The sheriffs were elected without incident, but when those present were asked to re-elect John Chichele, who had served as chamberlain since 1434, ‘the greatest number of the commonalty with loud voice and uplifted hands clamoured “Cotisbrok, Cotisbrok”’. In response to this challenge the mayor and aldermen ordered all those who had not been personally summoned to depart. A new election was held and this time Chichele was elected. As a former MP and a serving auditor Cottesbroke was certainly qualified for the post of chamberlain, and his abilities were rewarded by his re-election by the commonalty to the post of auditor on 13 Oct. Yet, as the City began its investigation into the disturbances, it became clear that his popular support stemmed as much from his own radical politics as it did from his abilities as an administrator. On 16 Oct. evidence was heard by the court of aldermen which confirmed that an armed rising had been planned for the mayoral election three days before. It was claimed by John Sturgeon*, who clearly had some connexion with the radicals, that Cottesbroke had been present at secret meetings held to plan the rising, along with the prominent tailor, John Bale, John Leving*, and others. Cottesbroke himself was questioned regarding allegations that he had displayed a copy of the ‘Great Charter’ of 1319 to his associates and in the City at large, and had impugned the rule of the mayor and aldermen. The significance of this charter was that it had conferred privileges upon the wider body of freemen which, according to the radicals, were being ignored by the ruling oligarchy. It was also a contention of the radicals that, as the charter had been confirmed by Parliament, it could not be overturned by the King’s writ, such as the one which had been obtained to restrict attendance at elections. This, in any case, was popularly believed to be a forgery. Consistent with this view was evidence given by Thomas Canynges in which he accused Cottesbroke of saying that those who had not voted for Thomas Catworth as mayor on 13 Oct. need not obey him.
The impact of his alliance with the radicals on Cottesbroke’s civic career was not immediately apparent, as he continued to serve as auditor until September 1444. Yet it is striking that very little is heard of him after that date, a fact which implies that his career of office-holding at least had come to a premature end. His position within the Grocers’ Company may have been precarious too, for his very visible opposition to the court of aldermen in 1443 had run counter to the Grocers’ own attempts to preserve their control over the offices of weigher and garbler in the City, for which they needed the support of the Drapers’ aldermen.
