What was the original name of the Assassin organization founded in Assassin's Creed Origins?

The original name of the Assassin organization founded in Assassin's Creed Origins was the Hidden Ones.

Bayek and Aya establish the Hidden Ones after confronting the Order of the Ancients, a secretive organization seeking political influence and control. Their new group adopts principles centered on protecting ordinary people and opposing domination by powerful rulers and manipulators.

The Hidden Ones are presented as the historical predecessor of the Assassin Brotherhood seen in later periods of the franchise. Their early creed and methods foreshadow the familiar maxim about avoiding harm to the innocent while working from the shadows.

The distinction matters because Origins is set centuries before the medieval Levantine Assassins depicted in the first game. The Order of Ancients is the opposing faction in Origins, not an earlier name for the Assassins. The Knights Templar belong to a later stage of the series' fictional history.
