The House of Yawar has been the head of the Shammar tribe for centuries. The Shammar is one of Iraq's biggest tribal confederations with more than 1.5 million people covering vast territories from Iraq into Syria and Saudi Arabia. Composed of both Sunnis and Shiites, the Shammar are generally religiously and politically moderate. "My mother would take me to visit the holy shrines in Najaf and Karbala, in addition to the Sunni mosques in Baghdad and St. Mary's Church," Yawar told the Iraqi paper "Al Zaman". This had an impact on al-Yawar's leadership approach later in his political career, and one that made a lasting impression. According to Jaffar Saheb Said, an elder at the northern Baghdad shrine of Imam Kadhem, a Shiite saint, "he's deep-rooted and well-known among Arab clans. He's able to navigate between both Shias and Sunnis and solve their problems."
