"I am home and I had almost forgotten its beauty."
– Spock, 2237 ("Yesteryear")
Ni'Var, formerly Vulcan, was an inhabited M-class planet in the 40 Eridani system of the Alpha Quadrant. It had no moons, but appeared to have close planetary companions. It was the homeworld of the Vulcans, a warp-capable humanoid species. (TOS: "The Man Trap", "Amok Time"; TAS: "Yesteryear"; Star Trek: The Motion Picture; VOY: "In the Flesh"; ENT: "Strange New World"; DIS: "Lethe", "Magic to Make the Sanest Man Go Mad", "Unification III")

Vulcan was a founding member of both the Coalition of Planets in 2155 and the United Federation of Planets in 2161. (ENT: "Zero Hour", "Demons", "Terra Prime", "These Are the Voyages...") During the Dominion War of the late 24th century, Vulcan's strategic importance was on par with worlds like Andor, Berengaria VII, and Earth. (DS9: "In the Cards", "In the Pale Moonlight")

In the post-Burn era, the planet – now called Ni'Var – became an independent world with the planetary government resolving centuries-old issues of reunification between the Romulans and the Vulcans. (DIS: "Unification III") In 3189, after the mystery of the Burn was solved and a repeat prevented, Ni'Var commenced negotiations to rejoin the Federation, doing so the following year. (DIS: "That Hope Is You, Part 2", "All Is Possible")
