what did the abbasids do to the government
Abbasid Caliphate The Abbasid Caliphate (/əˈbæsɪd/ or /ˈæbəsɪd/ Arabic: ٱلْخِلافَةُ ٱلْعَبَّاسِيَّة‎, al-Khilāfatu al-ʿAbbāsiyyah) was the third of the Islamic caliphates to succeed the Islamic prophet Muhammad. The Abbasid dynasty descended from Muhammad's uncle, Abbas ibn Abdul-Muttalib (566–653 CE), from whom the dynasty takes its name.[2] They ruled as caliphs for most of the caliphate from their capital in Baghdad in modern-day Iraq, after having overthrown over the Umayyad Caliphate in the Abbasid Revolution of 750 CE (132 AH).
House of Saud The House of Saud has gone through 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.
