Answer
The Laws of Hywel Dda were a set of Welsh laws that Owain Glyndŵr planned to reintroduce during his rebellion against English rule in the 15th century. These laws, originally compiled by Hywel Dda in the 10th century, covered a wide range of topics, including criminal justice, property rights, and family law. Owain believed that the reintroduction of these laws would help to restore Welsh independence and preserve Welsh culture.
