In 1913, Ibn Saud, with support from the Ikhwan, conquered al-Hasa from an Ottoman garrison, who had controlled the area from 1871. He then integrated al-Hasa and Qatif into the Emirate. The people in these areas were Shias and the Saudis Wahhabi puritans, resulting in harsh penalties for Shi'a Islam in Saudi Arabia, contrary to what the traditionally tolerant Sunni Ottomans allowed.
