The Emirate of Nejd and Hasa was the second iteration of the Third Saudi State from 1913 to 1921.

It was a monarchy led by the House of Saud.

[1] The state was formed after Saudi forces seized Al-Ahsa from the control of the Ottoman garrison, during the Conquest of al-Hasa.

It was the direct antecedent of the Sultanate of Nejd, and a legal predecessor of modern-day Saudi Arabia.
