What powers did the provincial estates have in the Spanish Netherlands?

In the Spanish Netherlands, the provincial estates (or assemblies) served as the most significant representative bodies. Their primary powers included:

• Taxation: The estates possessed the authority to levy and collect taxes, which allowed them to ensure that a substantial portion of tax revenue was utilized within the country.1
• Public Works: A permanent deputation, which was drawn from the estates, held the responsibility of supervising public works.1

While these provincial assemblies were influential, their collective power through the States General—which consisted of delegates from all the provincial estates—diminished significantly over time, eventually ceasing to meet after 1632.1
