10. The Dutch Republic

- Independent of: The Spanish Empire, especially the “Kingdom of Castile”
- Founder: Uncertain
- Known name today: Netherlands
Until the 16th century, many of the Dutch states consisted of duchies under the rule of the Holy Roman Empire. In the first half of the 16th century, these states first came under the rule of the French “Burgundy” family and then under the rule of the “Habsburg” royal family. During the Dutch revolution against Spain in the second half of the 16th century, most of the Dutch states gained independence according to the Act of Abjuration.

The decision to independence was made by the commander of the Dutch states; Because King Philip II, the ruler of Spain from the Habsburg dynasty, had not been able to fulfill his duties and suppress the rebels; That is, in practice, he lost his throne.
In the absence of a worthy ruler for the kingdom, the Dutch states moved towards the formation of a republic
After the revolution, a competent ruler who could rule the Dutch states was not found; For this reason, the newly independent states formed the Dutch Republic in order to take over the administration of the states. The Dutch Republic eventually became the Netherlands.
The Netherlands is the third country to have an elected parliament and is generally known for its progressive policies. This country is a founding member of many institutions and organizations, including the European Union and the Eurozone. The Netherlands ranks high in terms of freedom of the press, economic freedom, happiness, quality of life and human development and provides many social benefits to its citizens. The Dutch tax system is very egalitarian.
