Gondor and Arnor renew communications and form an alliance
Event Type: Political
Age: 3rd Age - The Kings
Years: 1936 ~ 1940
It was in the reign of Araphant in the North and of Ondoher son of Calimehtar in the South that the two kingdoms again took counsel together after long silence and estrangement. For at last they perceived that some single power and will was directing the assault from many quarters upon the survivors of Númenor. […] But neither kingdom was able to send help to the other; for Angmar renewed its attack upon Arthedain at the same time as the Wainriders reappeared in great force.
The Return of the King, LoTR Appendix A, Annals of the Kings and Rulers: Gondor and the Heirs of Anárion
Angmar recovers and makes war on the Dunedain. Araphant seeks to renew ancient alliance and kinship with Gondor. […] But Gondor is engaged in the long Wars of the Wainriders, and sends little help.

The Kings of Arthedain ... maintained a special warden at Amon Sûl, whose Stone was held to be the chief of the Northern palantíri, being the largest and most powerful and the one through which communication with Gondor was mainly conducted.

[Note 1: This must take place after Ondoher becomes King of Gondor in 1936 and before Arvedui, heir of Araphant, weds Fíriel, daughter of Ondoher in 1940 as a result of the renewed communications.]
