A rebel movement within the ranks of the Jaffa during the existence of the Goa'uld empire, scattered throughout the Goa'uld territories. The resistance was forged in large part by the efforts of Teal'c and Bra'tac. Thanks to Teal'c, the Jaffa Rak'nor was also an influential leader in the movement. When the Goa'uld were overthrown, the movement gave birth to the Free Jaffa Nation.
The group opposed oppression by Goa'uld, who would use Jaffa as their armies and incubators to their symbiotes. Their message was freedom from slavery, and that without them the Goa'uld were powerless. While the group succeed in winning many converts, they also suffered heavy losses at the hands of the Goa'uld and those Jaffa who remained loyal to the false gods. One gathering of the Jaffa resistance -- under the leadership of Kytano, who was revealed to be the Goa'uld Imhotep -- proved to be a trap, with dozens of their leaders massacred by Goa'uld forces.
The Jaffa M'zel was also a resistance leader, who led the Jaffa in withdrawing from Earth's Alpha Site, believing that they must build their own communities and learn to stand on their own feet before relying on allies.
Now the leaders of the once underground movement must forge a new government for their people, and continue to work to convince various Jaffa factions across the galaxy to cast off the old ways and embrace their freedom.
