Vidugavia

King of Rhovanion.

in Appendix A (I, iv) to The Lord of the Rings, there is a piece of information saying that Vidugavia, who called himself King of Rhovanion, was the most powerful of the princes of the Northmen.

He was shown favour by Rómendacil II King of Gondor (died 1366), whom he had aided in war against the Easterlings, and the marriage of Rómendacil's son Valacar to Vidugavia's daughter Vidumavi led to the destructive Kin-strife in Gondor in the fifteenth century.
