Archanis IV was the inhabited fourth planet orbiting the primary Archanis. This star, located near to the Federation-Klingon border, was in the Archanis sector, in the Beta Quadrant. (TOS: "Day of the Dove"; DS9: "Broken Link"; DIS: "Context Is for Kings")

In the late 2260s, an alleged Federation research outpost on this planet was attacked by unidentified raiders. A hundred civilians were killed in the raid. This was one of several incidents that had taken place since a truce was declared between the Federation and the Klingon Empire. Although there was no proof of Klingon involvement in these incidents, some in the Federation believed them responsible. The Klingons claimed that they had observed the treaty to the letter for three years and that they were not responsible for the raids. In 2268, while under the influence of the Beta XII-A entity, Pavel Chekov was made to believe he had once had a brother, Piotr Chekov, who had been killed by the Klingons at the research outpost on Archanis IV. In reality, he had no brother; the entity wished to foment hostility between the crew of the USS Enterprise and the Klingons. (TOS: "Day of the Dove")

Circa 2272, the Klingons relinquished their claim on the Archanis sector to the Federation. (DS9: "Broken Link")

The Star Trek Chronology (2nd ed., p. 90) suggests this was more likely a concession made at the Khitomer Conference in 2293, rather than a result of the recently signed Treaty of Organia, which had provisions for the changing hands of planets.

Prior to the beginning of the Federation-Klingon War, Gowron sent a message to the Federation Council, telling them to abandon all starbases and military installations in the sector. During the war, the planet was raided by a Klingon force. As a condition of ending the war, Chancellor Gowron stated that the Federation must allow the Klingon Empire to annex Archanis and other worlds captured by Klingons. Captain Benjamin Sisko told the Klingon leader that he couldn't count on that condition being met. (DS9: "Broken Link", "Apocalypse Rising", "Nor the Battle to the Strong")

Background information Edit

This planet was only mentioned in dialogue.

"are-KANE-is" was the pronunciation for this planet's name from the script pronunciation guide for "Broken Link".

This planet, introduced in "Day of the Dove", was originally to have been called Alpha IV. On 13 August 1968, however, Kellam de Forest suggested changing the planet's name to Arcanis IV, as the name Alpha IV did "not conform with proper astronomical nomenclature." [1] Thereafter, in the revised final draft script of "Day of the Dove", the name of this planet was spelt "Arcanis 4".

The fate of Archanis IV after the brief Federation-Klingon war ended in mid-2373 has not been revealed on screen.

According to the Star Trek: Star Charts ("United Federation of Planets I"), in 2378, Archanis IV was a Federation member.
