It is worthy of note that during Brembre's mayoralty, in 1378, Nicholas Twyford, one of the sheriffs, was brought up for contumacy towards the Mayor, and punished for the same. There had been a conflict in Cheapside between the goldsmiths and the pepperers (grocers), and John Worsele, one of the sheriff's suite, was brought before the Mayor as a principal mover in the strife. Twyford refused to do the Mayor's behests as to the imprisonment of his follower after arrest.[231] With the fall of the King, Brembre also fell, and there was a revolution in the government of the city as well as in that of the country. Northampton was released from Tintagel Castle, and restored to his property; and Brembre was tried for his life, condemned to death, and executed in the Tower in February 1388. The companies who petitioned for Brembre's punishment were Mercers, Cordwainers, and eight others, all opposed to the victualling trades. In 1387 a proclamation was made in the city, by the King's command, forbidding, on pain of death and forfeiture of goods, all true lieges of London to speak evil of the King and Queen. The issuing of this proclamation in the city formed one of the charges of high treason against Brembre and his followers. In this same year, 1387, a book of civic regulations called _Jubile_, promulgated by John de Northampton and his party, was ordered to be burnt. Mr. Riley refers to the petitions in Parliament for 1386-1387,[232] where we learn from the petition of the Cordwainers against Nicholas Brembre and his adherents that in this book of _Le Jubile_ 'were comprised all the good articles pertaining to the good governance of the said city, and that Nicholas Extone, the Mayor, and all the aldermen and good Commons of the city had sworn for ever to maintain them, to the honour of God and the profit of the common people; but that the said Nicholas Extone and his accomplices have burnt it without consent of the good Commons of the city, to the annihilation of many good liberties, franchises and customs of the city.'[233] The feuds of those days continued to agitate the city for some years, but at last the differences between the various trades cooled down somewhat. In 1391, however, a proclamation was issued that 'no person shall speak or give his opinion as to either Nicholas Brembre or John Norhamptone' on pain of imprisonment for a year and a day. The preamble is as follows: 'Whereas many dissensions, quarrels and false reports have prevailed in the City of London as between trade and trade, person and person, because of divers controversies lately moved between Nicholas Brembre, knight, and John Norhamptone, of late Mayors of the same city, who were men of great power and estate, and had many friendships and friends within the same; to the great peril of the same city, and maybe of all the realm.'[234]
