Why did trial by ordeal and combat end?

Trial by ordeal and combat gradually ended due to the rise of more rational legal systems that emphasized evidence and due process over supernatural judgments. As societies evolved and the Enlightenment promoted reason and empirical evidence, these methods were increasingly viewed as barbaric and unreliable. Additionally, the influence of the Church and legal reforms sought to establish fairer, more humane approaches to justice, ultimately leading to the abandonment of these practices in favor of structured legal procedures.
