The Dutch Revolt was the result of oppression by the monarch of Spain, at that time Philip II. So the people rose up, the start of the famous Dutch Revolt.
Philip II was concerned that the Dutch people had too much freedom. So he started cutting down on that freedom in different ways. One way was to impose taxes. Another more serious way was to bring the Inquisition over and to try and use its power to subjugate the people, especially the Protestants. The people, naturally, detested him for this, Catholic and Protestant alike, and so they rebelled.
William of Orange was a landholder in Germany. He had Protestant parents but he was raised by the king to be a Catholic. However, in his later years, he turned back to Protestantism. He led the Dutch Revolt for a time, and earned the nickname ‘William the Silent’ by remaining quiet when an announcement was made against the Protestants by the king. At the meeting he was posing as a Catholic. This information saved many Protestant lives.
Eventually the people, after much hard work and loss of precious lives, earned their freedom. They became their own country. They set forth a movement and a system called the demonstration effect. It was system where the citizens had rights to property, personal rights, etc., and the laws were obeyed with a surety and promptness remarkable for the times. Respect for land and rights were observed strictly, by the government and people in powerful positions.
By fighting for their freedom and the demonstration effect, the Dutch people set an example which some chose follow, the path to freedom.
