Salomon, King of Brittany

In 851, Charles the Bald, after his defeat at the Battle of Jengland, made peace with Salomon's cousin Erispoe, son of Nominoe, and granted him the counties of Rennes and Nantes and the Pays de Retz in Poitou as far as the river Mayenne.

[3] In 859, a synod met at Savonnières near Toul and tried to order Salomon to remember his oath of 852 and to resume paying the tribute which Brittany had paid in years past.

[5] Salomon also lent a force of Bretons to aid Louis the Stammerer, now in league with the rebels, in his war with Robert.

[6] This was the start of a new insurrection; even Pope Nicholas I wrote letters to Salomon urging him to resume the halted tribute payments.

Perhaps he simply wished to break the deadlock which had ensued following Nominoe's deposition of five Breton bishops a decade and a half earlier.

In 874, a conspiracy involving Pascweten, Wrhwant, and Wigo, son of Riwallon, Count of Cornouaille, plotted to kill Salomon.
