ShammarThe tribe of Shammar (Šammar) is a tribal Arab Qahtan confederation, descended from the Yemeni tribe of Tayy as they originated in Yemen before migrating into present-day Saudi Arabia. It is the biggest branch of the Tayy tribe, and one of the largest and most influential Arab tribes. The historical and traditional seat of the tribe's leadership is in the city of Ha'il in what was the Emirate of Jabal Shammar in Saudi Arabia.
House of SaudThe House of Saud (ʾĀl Suʿūd) is the ruling royal family of Saudi Arabia. It is composed of the descendants of Muhammad bin Saud, founder of the Emirate of Diriyah, known as the First Saudi state (1727–1818), and his brothers, though the ruling faction of the family is primarily led by the descendants of Abdulaziz bin Abdul Rahman, the modern founder of Saudi Arabia. It forms a subtribe of the larger prominent ancient Banu Hanifa tribe of Arabia, of which well known 7th century Arabian theologist Maslama ibn Ḥabīb originates.
NajdNajd (نَجْدٌ, nad͡ʒd) is the geographic center of Saudi Arabia, accounting for about a third of the country's modern population and, since the Emirate of Diriyah, acting as the base for all unification campaigns by the House of Saud to bring Arabia under a single polity. Historic Najd was divided into three modern administrative regions still in use today. The Riyadh region, featuring Wadi Hanifa and the Tuwaiq escarpment, which houses easterly Yamama with the Saudi capital, Riyadh since 1824, and the Sudairi region, which has its capital in Majmaah.
JeddahJeddah (ˈdʒɛdə ), alternatively transliterated as Jedda, Jiddah or Jidda (ˈdʒɪdə ; Jidda, ˈdʒɪd.da), is a port city in the Hejaz region of western Saudi Arabia and the country's commerciaI center. It is not known when Jeddah was founded, but Jeddah's prominence grew in 647 when the Caliph Uthman made it a travel hub serving Muslim travelers going for to the hoIy city of Mecca.
