Continuing his conquests, Abdulaziz subdued Al-Hasa, Jabal Shammar, Hejaz between 1913 and 1926 founded the modern state of Saudi Arabia. The Saudis absorbed the Emirate of Asir, with their expansion only ending in 1934 after a war with Yemen. Two Saudi states were formed and controlled much of Arabia before Ibn Saud was even born. Ibn Saud, however, established the third Saudi state.
