Here's a breakdown:
* Oppression: The story depicts an oppressive regime under the rule of Gessler, the tyrannical Austrian governor, who imposes harsh laws and tries to enforce his authority through fear and violence.
* Resistance: William Tell, a skilled archer and a symbol of Swiss independence, embodies the spirit of resistance against Gessler's rule. His defiance is fueled by the unjust laws, the mistreatment of his people, and the threat to his son's life.
* The Act of Defiance: Tell's legendary act of shooting the apple off his son's head is a powerful act of defiance, showcasing his courage, skill, and unwavering commitment to his people's freedom.
* Ultimate Triumph: The story concludes with Tell's escape, which inspires others to rise up against Gessler's tyranny. This leads to the downfall of the oppressive regime and ultimately, the liberation of Switzerland.
Therefore, the main idea of the William Tell story is that even against overwhelming power, one person's courage and defiance can ignite a revolution and bring about freedom and justice. It's a story about the fight for liberty and the triumph of the human spirit.
