House of Isildur

The House of Isildur were the descendants of Isildur, elder son of Elendil. The House came close to destruction at the beginning of the Third Age, when Isildur and his three eldest sons were lost at the Disaster of the Gladden Fields. His youngest son Valandil was kept safe in Rivendell, however, and from him came the line of the Kings of Arnor that led over three thousand years to Aragorn II Elessar.

== The Realm of Arnor ==
Elendil and his two sons, Isildur and Anárion founded the two Númenórean realms in exile: Arnor and Gondor. Elendil was the High King of all of the Dúnedain but the rule of the southern Kingdom of Gondor was delegated to joint rule under his sons. In the War of the Last Alliance
Elendil and Anárion both died and Isildur became the new High 
King. When he left Gondor to take up his kingship in Arnor he delegated
rule of Gondor to Anárion’s son, Meneldil. However, after the Disaster of the Gladden Fields the two realms were sundered, with the Kings of Gondor descending from the House of Anárion and the Kings of Arnor descending from the House of Isildur.
After the split of the North-kingdom into three, the Kings of Arthedain formed the senior and ultimately the only line of the House of Isildur, as the branches in Cardolan and Rhudaur quickly became extinct.
Following the fall of the North-kingdom the Chieftains of the Dúnedain continued the line and were also descended from Anárion through Fíriel, daughter of King Ondoher and mother of Aranarth. At the end of the War of the Ring, Aragorn II Elessar became King of Gondor and re-founded the realm of Arnor, becoming the first High King of all the Dúnedain since Isildur.
