He was born in TA 1126, the last year of the long reign of Hyarmendacil I as Minalcar and he rose to a powerful position early because his uncle Narmacil I (first son of Atanatar II) felt uncomfortable with the Kingship.
He was Regent from TA 1240 and struck a decisive blow against the Easterlings whom he defeated near the Sea of Rhûn. He also fortified Gondor and made pacts with the Northmen of Rhovanion, all before he took the throne. After Narmacil's death, he remained Regent for ten years under his father Calmacil.
When he finally ascended to the throne after the death of his father, he immediately took the name Rómendacil, the East-victor, as his distant forefather Tarostar had done.
To cement an alliance with the Northmen, Rómendacil II sent his son Valacar as an ambassador. While Valacar was on his mission he married Vidumavi, the daughter of Vidugavia, the King of Rhovanion, which would ultimately lead to the disastrous Kin-strife.
Rómendacil died in TA 1366 after sixty-two years of rule and was succeeded by Valacar.
