The year 1285 was a memorable one both for London and the kingdom. It witnessed the passing of two important statutes. In the first place the statute _De Donis_ legalised the principle of tying up real estate, so as to descend, in an exclusive perpetual line; in other words, it sanctioned entails, and its effect is still experienced at the present day in every ordinary settlement of land. In the next place the Assise of Arms of Henry II was improved so as to secure for the king a national support in the time of danger. In every hundred and franchise each man’s armour was to be viewed twice a year; and defaults reported to the king "who would find a remedy." The gates of walled towns were to be closed from sun-set to sun-rise, and watch and ward were to be kept as strictly as in times past, "that is to wit, from the day of the Ascension until the day of S. Michael, in every city by six men at every gate; in every borough, twelve men; every town, six or four, according to the number of the inhabitants of the town, and they shall watch the town continually all night from the sun-setting unto the sun-rising."(310) Three years previous to the passing of this statute the mayor, alderman and chamberlain had made very similar provisions for the keeping of the City of London, the city’s gates, and the river Thames.(311) (M196) For the city, the year was a memorable one, owing to the suspension of its franchise. The circumstances which caused the loss of its liberties for a period of thirteen years (1285-1298) were these. The king’s justiciars were sitting at the Tower, where the mayor, sheriffs, and aldermen of the city had been summoned to attend. Owing to some informality in the summons, Gregory de Rokesley, the Mayor, declined to attend in his official capacity, but formally "deposed himself" at the Church of All Hallows Barking—the limit of the city jurisdiction— by handing the city’s seal to Stephen Aswy or Eswy, a brother alderman. On entering the chamber where sat the justiciars, the mayor excused his unofficial appearance on the ground of insufficient notice. This was not what the justiciars had been accustomed to. On the contrary, the citizens had usually shown studied respect towards the justiciars whenever they came to the Tower for the purpose of holding pleas of the crown. (M197)
