The year 1433, the date of the incorporation of Holland and Zeeland in the Burgundian dominion, is therefore a convenient starting-point for a consideration of the character of the Burgundian rule in the Netherlands, and of the changes which the concentration of sovereign power in the hands of a single ruler brought into the relations of the various provinces with one another and into their internal administration. The Netherlands become now for the first time something more than a geographical expression for a number of petty feudal states, practically independent and almost always at strife. Henceforward there was peace; and throughout the whole of this northern part of his domains it was the constant policy of Philip gradually to abolish provincialism and to establish a centralised government. He was far too wise a statesman to attempt to abolish suddenly or arbitrarily the various rights and privileges, which the Flemings, Brabanters and Hollanders had wrung from their sovereigns, and to which they were deeply attached; but, while respecting these, he endeavoured to restrict them as far as possible to local usage, and to centralise the general administration of the whole of the "pays de par deçà" (as the Burgundian dukes were accustomed to name their Netherland dominions) by the summoning of representatives of the Provincial States to an assembly styled the States-General, and by the creation of a common Court of Appeal.
