Civilization first dawned on Pa'ri around 2700 B.C. and finally stabilized around 1861. During the First Shadow War Pa'ri was attacked by the Tak'cha after the Yolu declined to join Valen's alliance to fight the Shadows in favour of remaining neutral. Enraged by this assault on an innocent world, Valen expelled the Tak'cha from the alliance and all mention of them would be expunged from Minbari history. Originally a member of the League of Non-Aligned Worlds, Pa'ri joined the Interstellar Alliance in 2261. Pa'ri was among the first worlds of the Alliance to send recruits to Minbar to be trained as Anla'shok.
