In this reign were several other dreadful fires, and London bridge was in 1091 carried away by a land flood; but a few years after another wooden bridge was built in its room. In 1099 a high flood caused the Thames to overflow its banks, by which a great number of villages were laid under water, and many of their inhabitants drowned: at this time part of the lands belonging to Godwin Earl of Kent, were swallowed up by the sea, and are now denominated Goodwin’s Sands; and this being a reign of prodigies, there happened fifteen years after such a defect of water in the river Thames, that numbers of people crossed not only above and below London bridge, but even through some of the arches, without wetting their feet. We have already mentioned the first charter granted by William the Conqueror to the city; he afterwards granted them another; but London obtained one much more extensive from Henry I. by which the citizens not only had their ancient customs and immunities confirmed, but the county of Middlesex added to their jurisdiction, on paying the quit rent of 300l. a year; with a power of appointing not only a Sheriff but a Justiciary from among themselves. This was granted to prevent that county’s being any longer an asylum for bankrupts, and fraudulent persons, who having deserted London with the goods and effects of their creditors, lived there in open defiance of those they had injured. By this charter the citizens were allowed the privilege of not being compelled to plead without the walls of the city, and excused from paying scot, lot, and danegelt, duties payable to the King by all his other subjects. The city was not to be amerced for the escape of a murderer; nor any citizen, when accused of a crime, be obliged to vindicate his innocence by a duel. They were exempted from paying toll in fairs or markets in any part of the kingdom; and if any was exacted, they might make reprisals in London, upon the inhabitants of the town where it was exacted, &c. Before the grant of this charter, London seems to have been entirely subject to the arbitrary will of the King. But the liberties of the citizens being now guarded by so strong a fence, they endeavoured to secure their customs by converting them into written laws; and the several bodies professing the arts and mysteries of trade and manufacture, which had hitherto been kept up by prescription only, were now strengthened by being formed into established companies. The King however reserved to himself the power of appointing the Portreve, or chief officer of the city.
