Saudi Arabia tribes are the tribes that appeared in Arabian Peninsula. Ancient genealogists of 14th century believed that there were three kinds of Arabs. One of them is Perishing Arabs. There is no much information about this kind of tribe because reasons of their perishing were genocide and their own decadence. Second kind of tribes is Qahtanite Arabs, also known as Pure Arabs, who were from Yemen. They are also believed to be descendants of Ya‘rub bin Yashjub bin Qahtan. And the third kind of ancient Saudi Arabia tribes are Arabized Arabs, who are also called Adnani Arabs; they originate from the first son of the patriarch Abraham. It is believed by genealogists that Muhammad was one of the Adnanite Arabs. Modern historians say that distinction between Qahtanite Arabs and Adnani Arabs lacks evidences, and they think that such distinction appeared because of fact fighting during the Umayyad period.
One of the most well-known modern tribes in Saudi Arabia is Ajman. Ajman is a tribal confederation, which is situated in northeastern Saudi Arabia. Members of this famous tribe are widely spread across such countries as Kuwait, Qatar, U. A. E. and Saudi Arabia. The word «Ajman» itself can be translated as «Persians». They were very strong during battles, that is why they were very important players in wars and politic conflicts during 19th and early 20th centuries in central Arabia. One section of this tribe military supported Ibn Saud, but later the tribe rebelled against him. Nearly all the members of Ajman tribe members gave up on nomadic life and decided to live on the territories of Persian Gulf states.
Another well-known tribe is the Jubur tribe; it is the largest tribe in Iraq. The Al Jubur tribe is a Bedouin Arabian tribe that used to govern Eastern Arabia and the island of Bahrain. After the Portuguese intrusion, their standard broken down and for the most part fled to Iraq in the sixteenth century. They settled generally in Nineveh, Northern Iraq. The Al Jubur tribe generally takes after the religion of Sunni Islam. Today only a little measure of the tribe still lives in Bahrain and are faithful to the Al-Khalifa government. The Al Jubur tribe has regularly kept up a well-disposed association with its neighboring Shammar tribe, particularly in Northern Iraq. Some members of the tribe lived in Hawija during the eighteenth century. The Jubur were Sunni Muslims but in the nineteenth century some of them began to change over to Shi'ism. Nevertheless, in 2014 and 2015 onwards the Jubouri tribe has fought against the Islamic State of Iraq and the Levant and has retaken control of urban areas and towns in North Iraq. After that, in March 2015, the Jubur tribe and the Iraqi Armed Forces are confronting with the Islamic State of Iraq.
In conclusion, Suadi Arabia region is very rich in terms of tribe diversity. For most people arabians can be just one nation but looking deep inside there are lots of tribes such as Ajman, Jubur, Qahtanite and others. The extent of the number of inhabitants in Saudi Arabia that claims a tribal association is obscure. About every single roaming people are sorted out in tribal affiliations, and in 1950 Saudi Arabia's itinerant populace was assessed at 50 percent.
