The Governor who possessed the confidence of Londoners, although all the rest of the country was against him, needed not to despair, while he who had the support of the rest of the country, but was opposed by London, could not be considered as triumphant. The so-called Heptarchy was constantly changing the relative positions of its several parts, until Egbert, the King of Wessex, became 'Rex totius Britanniæ' (A.D. 827). The seven kingdoms were at some hypothetical period 1. Kent, } 2. Sussex, } South of the Thames. 3. Wessex, } 4. Essex, } 5. East Anglia, } North of the Thames. 6. Mercia, } 7. Northumbria } North of the Humber, (including Deira } and as far north as the and Bernicia), } Forth. The walled city of London was a distinct political unit, although it owed a certain allegiance to one of the kingdoms, which was the most powerful for the time being. This allegiance therefore frequently changed, and London retained its identity and individuality all through. Essex seems seldom to have held an independent position, for when London first appears as connected with the East Saxons the real power was in the hands of the King of Kent. According to Bede, Wini, being expelled from his bishopric of Wessex in 635, took refuge with Wulfhere, King of the Mercians, of whom he purchased the See of London. Hence the Mercian King must then have been the overlord of London. Not many years afterwards the King of Kent again seems to have held some jurisdiction here. From the laws of the Kentish Kings, Lhothhere and Eadric, 673-685, we learn that the Wic-reeve was an officer of the King of Kent, who exercised a jurisdiction over the Kentish men trading with or at London, or who was appointed to watch over their interests.[15] There is a very interesting question connected with the position of the two counties in which London is situated. It is necessary to remember that London is older than these counties, whose names, viz., Middlesex and Surrey, indicate their relative position to the city and the surrounding country. We have neither record of their settlement nor of the origin of their names. Both must have been peopled from the river. The name Middle Saxons clearly proves that Middlesex must have been settled after the East and West Saxons had given their names to their respective districts. There has been much discussion as to the etymology of Surrey, more particularly of the second syllable. A once favourite explanation was that Surrey stood for South Kingdom (A.S. _rice_), but there is no evidence that Surrey ever was a kingdom, and this etymology must surely be put aside.
