The House of Saud has had three phases: the Emirate of Diriyah, the First Saudi State (1744–1818), marked by the expansion of Wahhabism; the Emirate of Nejd, the Second Saudi State (1824–1891), marked with continuous infighting; and the Third Saudi State (1902–present), which evolved into Saudi Arabia in 1932 and now wields considerable influence in the Middle East. The family has had conflicts with the Ottoman Empire, the Sharif of Mecca, the Al Rashid family of Ha'il and their vassal houses in Najd, numerous Islamist groups both inside and outside Saudi Arabia and Shia minority in Saudi Arabia.
