three largest kingdoms, those of Northumbria, Mercia and Wessex, were the most powerful.was not until a century later that one of these kings, King Offa of Mercia (757-96), claimed " kingship of the English ". He had good reason to do so. He was powerful enough to employ thousands of men to build a huge dyke, or earth wall, the length of the Welsh border to keep out the troublesome Celts. But although he was the most powerful king of his time, he did not control all of England.power of Mercia did not survive after Offa's death. At that time, a king's power depended on the personal loyalty of his followers. After his death the next king had to work hard to rebuild these personal feelings of loyalty. Most people still believed, as the Celts had done, that a man's first duty was to his own family. However, things were changing. The Saxon kings began to replace loyalty to family with loyalty to lord and king.and societySaxons created institutions which made the English state strong for the next 500 years. One of these institutions was the King's Council, called the Witan. p align="justify"> The Witan probably grew out of informal groups of senior warriors and churchmen to whom kings like Offa had turned for advice or support on difficult matters. By the tenth century the Witan was a formal body, issuing laws and charters. It was not at all democratic, and the king could decide to ignore the Witan's advice. But he knew that it might be dangerous to do so. For the Witan's authority was based on its right to choose kings, and to agree the use of the king's laws. Without its support the king's own authority was in danger. The Witan established a system which remained an important part of the king's method of government. Even today, the king or queen has a Privy Council, a group of advisers on the affairs of state.Saxons divided the land into new administrative areas, based on shires, or counties. These shires, established by the end of the tenth century, remained almost exactly the same for a thousand years. "Shire" is the Saxon word, "county" the Norman one, but both are still used. (In 1974 the counties were reorganised, but the new system is very like the old one.) Over each shire was appointed a shire reeve, the king's local administrator. In time his name became shortened to "sheriff". Saxon technology changed the shape of English agriculture. The Celts had kept small, square fields which were well suited to the light plough they used, drawn either by an animal or two people. This plough could turn corners easily. The Anglo-Saxons introduced a far heavier plough which was better able to plough in long straight lines across the field. It was particularly useful for cultivating heavier soils. But it required six or eight oxen to pull it, and it was difficult to turn. This heavier plough led to changes in land ownership and organisation. In order to make the best use of village land, it was divided into two or three very large fields. These were then divided again into long thin strips. Each family had a number of strips in each of these fields, amounting probably to a family "holding" of twenty or so acres. Ploughing these long thin strips was easier because it avoided the problem of turning. Few individual families could afford to keep a team of oxen, and these had to be shared on a co-operative basis.of these fields would be used for planting spring crops, and another for autumn crops. The third area would be left to rest for a year, and with the other areas after harvest, would be used as common land for animals to feed on. This Anglo-Saxon pattern, which became more and more common, was the basis of English agriculture for a thousand years, until the eighteenth century.needs only a moment's thought to recognise that the fair division of land and of teams of oxen, and the sensible management of village land shared out between families, meant that villagers had to work more closely together than they had ever done before.Saxons settled previously unfarmed areas. They cut down many forested areas in valleys to farm the richer lowland soil, and they began to drain the wet land. As a result, almost all the villages which appear on eighteenth-century maps already existed by the eleventh century.each district was a "manor" or large house. This was a simple building where local villagers came to pay taxes, where justice was administered, and where men met together to join the Anglo-Saxon army, the fyrd. The lord of the manor had to organise all this, and make sure village land was properly shared. It was the beginning of the manorial system which reached its fullest development under the Normans.first the lords, or aldermen, were simply local officials. But by the beginning of the eleventh century they were warlords, and were often called by a new Danish name, earl. Both words, alderman and earl, remain with us today: aldermen ar...
