Wales in the early Middle Ages covers the time between the Roman departure from Wales c. 383 and the rise of Merfyn Frych to the throne of Gwynedd c. 825. In that time there was a gradual consolidation of power into increasingly hierarchical kingdoms. The end of the early Middle Ages was the time that the Welsh language transitioned from the Primitive Welsh spoken throughout the era into Old Welsh, and the time when the modern Anglo-Welsh border would take its near-final form, a line broadly followed by Offa's Dyke, a late eighth-century earthwork. Successful unification into something recognisable as a Welsh state would come in the next era under the descendants of Merfyn Vrych.
