British Isles, 610-750 (Saint Muhammad)

The following is a timeline of the British Isles in the Saint Muhammad timeline.

(NOTE: I consider the British Isles part of, but since the POD impacts Britain more harshly than Europe, at least originally. The TL begins in 633, with the first intervention of the Middle East in Britain.)


 * 633: The Byzantines have a treaty with the King of Gwynedd so to get troops in the seemingly inevitable . Giving him a huge amount of gold and superior weaponry, is able to defeat the Northumbrians in battle single-handedly despite being outnumbered. This event gains him the admiration of most Celtic tribes and even respect from the King of Mercia. Oswald of Bernicia dies in the battle and Deira and Bernicia lose their chance of unification.
 * 634: Cadwallon, not satisfied with his victory over the Bernicians, withdraws from Anglo-Saxon England and attacks Powys with his army. Surprised, it easily falls to Gwynedd's army.
 * 635: Cadwallon marries the King of Strathclyde's daughter and his daughter marries the king's firstborn son, cementing the union between the two Brythonic kingdoms. Cadwallon also keeps his alliance with the Byzantines sending his own troops to help the Byzantines with the Persians. Relying on Cumbric aid on this time, while he waits for his troops to return, he begins building Cadwallon's Dyke (Clawdd Cadwallon).
 * 640: Penda of Mercia attempts to attack Gwynedd while it is weak, not counting on Cadwallon's good leadership skills and the armies of Strathclyde attacking it from the north, plus further fortifications in Cadwallon's Dyke. The war goes into stalemate for fifteen years.
 * 655: The remains of the Welsh army in the west finally return to Wales, and with extra aid, the Gwynedd-Strathclyde army breaks through the Mercian stalemate and soon seize over large parts of the westernmost Heptarchy. However, both the king of Strathclyde and his son die in battle (it is claimed by some, killed by Cadwallon so to ascend to the throne) and Gwynedd and Strathclyde are united into the new.
 * 656: A peace is signed between Mercia and Prydain, with the territory until the Seyern River going to Wales and the King of Mercia paying tribute to the Pyrdish king.
 * 657: Pyrdain bullies the rest of the Welsh kingdoms into joining Pyrdain as autonomous duchies.
