Brehon Law refers to the ancient legal system of Ireland that was in use before the English conquest. It is named after the Brehons, who were the judges responsible for interpreting and applying these laws. Brehon Law was based on customary practices and focused on restitution rather than punishment, emphasizing compensation for wrongs done. The legal system was characterized by its flexibility and adaptability, allowing for local customs to influence decisions. It covered various aspects of life, including property rights, marriage, and social obligations, reflecting the values and norms of Irish society during its time.
