Run of Strathclyde ^{1 2}

   Another name for Run was Rhun f Arthgal.

  General Notes:

The Vikings had laid siege to Dumbarton for four months in 870, eventually defeating the inhabitants when they cut off their water supply. The Norse king Olaf returned to the Viking city of Dublin in 871, with two hundred ships full of slaves and looted treasures. Olaf came to an agreement with Constantine I, king of Scots, and Arthgal f Dyfnwal (son of Dyfnwal), king of Strathclyde, was executed. Rhun f Arthgal, brother-in-law of Constantine, became king of Strathclyde, apparently as a client or sub-king of Constantine.

Rhun was to die c. 878, possibly in the same battle as Constantine, who was killed fighting the Norse. He was succeeded by Eochaid f Rhun, who allied himself with Giric f Dungal of the Scots. The two reigned jointly over Alba and Strathclyde until 889, when they were expelled, effectively ending Strathclyde's status as an independent state, c. 890.

  Noted events in his life were:

• He was a King of Strathclyde.

Run married daughter of Kenneth, daughter of Kenneth I of Scotland and Unknown.
