Deheubarth was a historical kingdom located in the southern part of Wales. It emerged in the 9th century and was known for its rich culture and political significance. The kingdom was formed from the unification of several smaller territories and played a crucial role in the resistance against Viking invasions. The name "Deheubarth" translates to "the southern part," reflecting its geographical position. It was ruled by various notable figures, including Rhys ap Tewdwr, who became a prominent leader in the 11th century. The kingdom eventually fell under the control of the Normans in the late 11th century, leading to significant changes in the region.
