Lleuenydd was a relatively unimportant piece of land until the rise of Gwrwst, whose personal prowess would unite a relatively large portion of the British under one banner. After his death it would be relegated to a subservient status for the remainder of its existence, first under Arthur and later under Urien.
Lleuenydd was only given autonomy in the last few decades of Rome's presence on the island. That and its northwestern location allowed it to survive the initial onslaught of Germanic tribes and former foederati in the years around 441.
