Why was William the 1st called William the silent?

William I, known as William the Silent, earned this title due to his reserved and diplomatic nature, particularly in contrast to the more aggressive leaders of his time. He was a key figure in the Dutch Revolt against Spanish rule and often employed strategic silence to enhance his political maneuvering. His ability to remain calm and collected in tense situations, while carefully planning his actions, contributed to his reputation as a silent yet formidable leader.
