Each of these sent their deputies to the General Assembly, but these deputies had to refer all matters to their principals before they could give their assent, and each body of deputies gave this assent separately, and without regard to the others.
It was thus but a first provisional step towards unity of administration, but it did tend to promote a feeling of community of interests between the provinces and to lead to the deputies having intercourse with one another and interchanging their views upon the various important subjects that were brought before their consideration.
The period of disturbance and the weakening of the authority of the sovereign, which followed the death of Charles the Bold, led to the States-General obtaining a position of increased importance; and they may from that time be regarded as forming a regular and necessary part of the machinery of government in the Burgundian Netherlands.

The States-General however, like the Provincial States, could only meet when summoned by the sovereign or his stadholder; and the causes for which they were summoned were such special occasions as the accession of a new sovereign or the appointment of a new stadholder, or more usually for sanctioning the requests for levies of money, which were required for the maintenance of splendid courts and the cost of frequent wars.

For not only the Burgundian princes properly so-called, but even Charles V, had mainly to depend upon the wealth of the Netherlands for their financial needs.

And here a distinction must be drawn.

For solemn occasions, such as the accession of a new sovereign, or the acceptance of a newly appointed governor, representatives of all the provinces (eventually seventeen) were summoned, but for ordinary meetings for the purpose of money levies only those of the so-called patrimonial or old Burgundian provinces came together.
