In 1119, Ahmad Sanjar, with the aid of the Kakuyid ruler Garshasp II and several other minor rulers, invaded Jibal and forced Mahmud II to cede him Mazandaran and other parts of western Iran. Bahram then joined Ahmad Sanjar. Ahmad Sanjar then ordered Ali to meet him at his court. Ali, however, disobeyed, and instead sent his son Shah Ghazi Rustam IV, who was also related to Ahmad Sanjar from his mother's side.
