Answer: Religious and economic reasons.
Step-by-step explanation:
It is possible to involve political reasons in the whole story. The Netherlands was one of the most powerful economic powers in the world during the 16th century. It was composed of seventeen provinces, but Spain held power. The uprising broke out primarily due to the efforts of the Spanish King Philip II to strengthen the central government. In addition to the above, the king worked intensively to strengthen Catholicism but also increased taxes. In such circumstances, there was a revolt of the Dutch in February 1566. The war was fought in several stages for decades. The country was divided into two parts: Spain still had dominance and the part under Dutch administration. Belgium will emerge from the Spanish part in the 19th century.
