Anglo-Saxon Institutions. 449-1066 41 will be readily seen how favourable was the state of so- ciety produced by commendation to the growth of courts presided over by great landholders. These courts were called hattmoots, probably to contrast them with the open-air courts of hundred and shire. They must be regarded as private courts, but the people of the time did not so think of them. Private courts were new, and they must wait some time before contrasting ideas of public and private jurisdiction could arise. It was an institu- tionally unconscious age.

Where such courts were held by them—and there were many instances in Edward the Confessor's reign—they did it as a special privilege or franchise from the crown, and it was looked on as a variant way of carrying on ordinary public juris- diction in part of a hundred. It has been said that the grants of bookland were at first made only to churches. Had they remained thus limited, they could not have caused changes of great importance. But their extension was inevitable, for there were nearly as many motives for making such grants to lay nobles as to bishops or abbots. The rapidly growing class of thegns was the class concerned. Whatever their origin,1 the thegns in the later Anglo-Saxon period were forming a nobility of wealth and birth about the rank in society of the later country gentlemen: a man "throve to thegnright" when he acquired a certain amount of land, and the rank was heritable. An aristocracy was growing through economic differentiation of the freemen. There is much about the thegn that reminds one of the feudal 1 See above, pp. 13, 14.
