How did early English jurors differ from modern trial jurors?

Early English jurors differed significantly from modern trial jurors in their fundamental role and the basis of their decision-making.

Originally, jurors in England functioned as neighborhood witnesses. They were expected to pass judgment based on their own personal knowledge of the facts or the parties involved in a case.1

In contrast, the role of the modern jury has evolved to be strictly impartial. Today, jurors are recruited at random from the general population and are tasked with determining the facts of a case based solely on the evidence presented to them in court, rather than on prior personal knowledge. This shift reflects the development of the common law system, which moved away from earlier, nonrational modes of trial—such as the ordeal—toward a process centered on the objective evaluation of testimony and proof.21
