The Al Bin Ali were the dominant group controlling the town of Zubarah on the Qatar peninsula, originally the centre of power of the Bani Utbah. After the Bani Utbah gained control of Bahrain, the Al Bin Ali had a practically independent status there as a self-governing tribe. They used a flag with four red and three white stripes, called the Al-Sulami flag in Bahrain, Qatar, Kuwait, and the Eastern province of the Kingdom of Saudi Arabia. Later, different Arab family clans and tribes from Qatar moved to Bahrain to settle after the fall of Nasr Al-Madhkur of Bushehr. These families included the House of Khalifa, Al-Ma'awdah, Al-Fadhil, Al-Mannai, Al-Noaimi, Al-Sulaiti, Al-Sadah, Al-Thawadi and other families and tribes.
