Such measures would have been beneficial to Belgium, but they needed a deep knowledge of and sympathy for local conditions to be carried out successfully. Neither the king nor his Dutch ministers (the Belgians remained always in a minority in the Cabinet) were able to realize the difficulties which stood in the way and the legitimate grievances which might easily be created by hasty action.
When Holland entered the union, she had a debt of nearly 2,000,000,000 florins, while Belgium's debt was much smaller (30,000,000). The latter was, nevertheless, obliged to bear half of the total liabilities and the heavy taxes rendered necessary by the king's enterprising policy. Besides, in the distribution of such taxes the interests of Belgium, still almost entirely agricultural, were sacrificed to those of commercial Holland. The latter stood for free trade, the former for protection. It is characteristic of the situation that the first sharp conflict between Belgian and Dutch deputies took place in 1821 over a bill imposing taxes on the grinding of corn and the slaughter of cattle. These immediate grievances overshadowed, in the minds of the Belgians, the encouragement given by the Government to Belgian trade and industry.
A similar disregard for existing conditions and long-established traditions brought about the failure of the measures taken by William I to promote education. Not content with creating new schools, he endeavoured to give the monopoly of public education to the State and to subject the existing private establishments (almost all led by priests) to official control. He further increased Catholic opposition by establishing a Philosophical College at Louvain, where all those intending to enter a seminary were obliged to study.
These examples show how premature was the idea of a "complete union" between the two countries--an idea put forward, no doubt, owing to the necessity of creating a strong centralized State on the northern boundary of France. Had the Dutch Government possessed as much political wisdom as the Austrian Minister at the court of The Hague, they would have realized that the "kingdom of the Netherlands would never be consolidated as long as the constitutional and administrative union was not replaced by a federal system."
