Sunni leaders met last weekend to unite in their cause and negotiate with Shiites and Kurds.
Two years after war dramatically changed Iraq's political landscape, the former ruling minority Sunnis are developing plans to participate in a government formed by elections they boycotted.
In a significant shift, several Sunni groups that hitherto shunned the political process met last weekend to create a unified front and set of demands that they will present to the Shiite and Kurdish leaders now hammering out a new government.
The meeting was a reversal for Sunni leaders who have supported insurgents and urged US troops to leave Iraq immediately.
The new effort, observers say, appears to be an admission that their strategy - to stop Iraq's election and denounce the formation of a new government - has failed. Bringing the former ruling class into Iraq's emerging power structure, they add, could help quell the insurgency.
"Participation of the Sunnis is both religiously important and politically important," says John Esposito, a professor at Georgetown University who specializes in Islam and international affairs. "It can establish a precedent for other Sunni leaders to become involved."
The significance of the conference was underscored by its attendees. Participants included members of the Muslim Scholars Association, a group of Sunni religious leaders, among them some of the most extreme figures who have influence with the insurgency.
Also present were leaders from cities in the "Sunni Triangle," including Mosul, Haditha, and Salam Pak, which is bubbling with insurgent activity. Representatives of Waqaf Sunna, the powerful administrating body of Sunni religious affairs, attended as well.
