It was consistent with Haakon's conciliatory disposition that he did not molest or depose his nephews, Gudröd Björnsson and Tryggve Olafsson, but confirmed them as kings in Viken. It appears, however, that, nominally at least, they recognized his overlordship. Other sons and grandsons of Harold the Fairhaired he met with the same friendliness, giving to each what he considered to be his due. As soon as peace was thus established, and there was no one left to dispute his power, Haakon devoted himself energetically to the improvement of the internal administration of his kingdom. He divided the country into _Thing-Unions_, or judicial districts, and by the aid of wise and experienced men greatly improved the laws. One famous code, called the Gulathings-law, has particularly shed lustre upon his name, and the enlargement and improvement of the Frostathings-law is also, by some of the sagas, attributed to him. The only radical change which he introduced was the breaking up of his father's feudal state, by the restoration of the allodium to the peasants. But this one change necessitated many others. When the king relinquished his right to tax the land, he thereby deprived himself of the ability to keep an army, and had to consign, in part, to the peasants themselves the defence of their respective districts. It was naturally the sea-coast which was most exposed to attack; and in the absence of all but the most primitive means of communication it became possible for an enemy to ravage long stretches of land, before the intelligence of his presence reached the king. In order to remedy this, Haakon ordered _varder_ or signal-fires to be lighted, at fixed intervals, all along the coast at the approach of an enemy; but he partly counteracted the good effect of the reform by the severe punishment with which he threatened those who, without adequate cause, lighted the _varder_. In order to obtain the means to defend the coast, he divided it into marine districts, each of which was bound, on demand, to place a fully manned and equipped ship of war at the disposal of the king. This was, of course, but another form of taxation, but was less distasteful to the peasants, because its purpose and necessity were obvious, and no degrading dependence was implied, since the people had again become the free possessors of the soil. Nevertheless there are indications that the personal tax, derisively called the nose-tax, which had been introduced by Harold, was continued, at least for a while, by Haakon; as it is expressly stated that his first ships of war were built by the income of the nose-tax.
