* Unification of Wales: Hywel Dda is credited with unifying much of Wales under his rule in the 10th century. This marked a significant period of stability and growth for the Welsh kingdoms, laying the groundwork for a stronger Welsh identity.
* Codification of Welsh Law: Hywel Dda is most famous for his "Laws of Hywel," which codified existing Welsh laws and customs. These laws covered a wide range of topics, from inheritance and property to social customs and criminal justice. The "Laws of Hywel" are considered a landmark achievement in Welsh legal history and provide valuable insights into Welsh society during that time.
* Symbol of Welsh Identity: Despite the fact that Hywel Dda ruled only a portion of Wales, his legacy has cemented him as a figure of unity and pride for the Welsh people. The "Laws of Hywel" are seen as a symbol of Welsh autonomy and cultural heritage, even after the Norman conquest of Wales.
* Inspiration for Welsh Nationalism: Hywel Dda's story has been used as an inspirational figure in the Welsh nationalist movement, highlighting the potential for unity and self-governance within Wales.
While the historical context of Hywel Dda's reign is complex and there's ongoing debate about the extent of his unification and the authenticity of the "Laws of Hywel," his legacy remains deeply embedded in the Welsh national consciousness.
