First Saudi state

The first Saudi state (Arabic: الدَّوْلَةُ السُّعُودِيَّةُ الْأُولَىٰ, romanized: ad-dawla as-suʿūdiyya al-ʾūlā), officially the Emirate of Diriyah (Arabic: إمارة الدرعية, romanized: ʾimāra ad-dirʿiyya), was a polity that existed on the Arabian Peninsula between 1744 and 1818. The emir of a Najdi town called Diriyah, Muhammad bin Saud Al Muqrin, and the religious leader Muhammad ibn Abd al-Wahhab signed a pact founding a socio-religious reform movement that propagated the Wahhabi religious doctrine under the political leadership of the House of Saud. They then proceeded to expand their state throughout the Arabian Peninsula, the Levant, the coast of the Iranian city of Bandar Abbas, and the Bab al-Mandab Strait.
