man carried a horn slung on his shoulder as he went about his work so that he could at once send out a warning to his fellow villagers or call them in chasing a thief or other offender. The forests were full of outlaws, so strangers who did not blow a horn to announce themselves were presumed to be fugitive offenders who could be shot on sight. An eorl could call upon the ceorl farmers for about forty days to fight off an invading group. There were several kingdoms, whose boundaries kept changing due to warfare, which was a sin according to the church. They were each governed by a king and witan of wise men who met at a witanegemot, which was usually held three times a year, mostly on great church festivals and at the end of the harvest. The king and witan chose the witan's members of bishops, eorldormen, and thegns [landholding farmers]. The king and hereditary claims played a major part in the selection of the eorldormen, who were the highest military leaders and often of the royal family. They were also chief magistrates of large jurisdictional areas of land. The witan included officers of the king's household and perhaps other of his retinue. There was little distinction then between his gesith, fighting men, guards, household companions, dependents, and servants. The king was sometimes accompanied by his wife and sons at the witanagemot. A king was selected by the witan according to his worthiness, usually from among the royal family, and could be deposed by it. The witan and king decided on laws, taxes, and transfers of land. They made determinations of war and peace and directed the army and the fleet. The king wore a crown or royal helmet. He extended certain protections by the king's peace. He could erect castles and bridges and could provide a special protection to strangers.
