The Kin-strife was a disastrous decades-long civil war in Gondor during the Third Age.



The unrest that eventually built up to the Kin-strife began when Valacar, the son of King Rómendacil II of Gondor, married a woman of the Northmen of Rhovanion, Vidunavi. She bore him a son, Eldacar, but many of the people of Gondor of Númenórean blood were angered by this mixing of the blood of Middle Men and Númenóreans, and the coastal provinces rebelled when Valacar grew old.


In TA 1432, when Eldacar succeeded his father, the already-present unrest grew into open rebellion. Many people saw Eldacar as a half-breed, therefore having no right to rule. The chief of them was his distant relative Castamir the Usurper, also known as the "Lord of Ships," who in TA 1437 usurped the throne, forcing Eldacar into exile. Castamir was supported by the people of the realm of Umbar, who sought revenge against Gondor. During the rebellion, Osgiliath was sacked, and the great Dome of Stars was lost along with the city's Palantír.

Castamir also murdered Eldacar's son and heir Ornendil. Eldacar fled to Rhovanion, and Castamir ruled in his stead.

A full decade later, in TA 1447, Eldacar returned with Rhovanion troops; at the same time, a rebellion against Castamir's cruel rule took place. Eldacar managed to kill Castamir at the Battle of Erui, but Castamir's sons and many of their supporters fled south to Umbar. Eldacar could not follow them, as the fleet was under Castamir's control.[1]


As a result of the conflict, Gondor lost the city of Umbar for four centuries and gained a new enemy in the Corsairs of Umbar and the descendants of Castamir's sons. Also, many Gondorians of Númenórean blood were killed during the civil war, leaving Gondor significantly weakened.

The Kin-strife was, along with the losses suffered in the Great Plague and Wainrider War, one of the chief reasons for the abandonment of the fortresses in and surrounding the lands of Mordor.
