under the regime. Nevertheless, the Caliphs and the Orthodox were not too happy about this and so, at least initially, welcomed the coming of the Orthodox Seljuks. The appeal of Shi'ism in Iran, evident here, later becomes the basis of Iranian nationalism in the Safavids. This is the nadir of the Abbasid Caliphate, with its secular power and prestige completely eclipsed.The origin of the name of Baghdad, , is itself obscure. The dad element looks like it is from the Indo-European verb "give," which we also see in Persian names like Mehrdad, "given by Mithra." With the first element, it could be Middle Persian "god," bag (Sanskrit bhaga), or Middle Persian "garden," bagh (also bagh in Punjabi, which looks like a borrowing from Persian -- the "gh" is not a voiced aspirate stop, as in Sanskrit or Hindi, but the fricative that is indicated, but not always pronounced, in Indian, i.e. Hindi and Urdu, borrowings from Persian or Arabic). My guess is that "garden" is more likely right, so that the meaning is probably "a garden is given," rather than "given by God." The complete genealogy of the Alids, Omayyads, and Abbasids is in The Cambridge History of Islam, Volume 1B, [edited by P.M. Holt, Ann K.S. Lambton, & Bernard Lewis, Cambridge University Press, 1970, pp.731-733]. Unfortunately, the diagrams contain no dates. Much the same information, with dates, is in The Arabs by Anthony Nutting [Mentor Books, 1964, p.202-203]. I have not found a complete genealogy of the Egyptian Abbasids. According to Bosworth's The New Islamic Dynasties [pp.7 & 9], the relationship of the two lines is uncertain anyway. Now, however, I have received from Derek Whaley a genealogy of the Egyptian Abbasids which he has assembled, with a connection to the main Abbasid line. Much of this can be confirmed in Bosworth, and I provide it, with a couple of additions and corrections, here, formerly just in a popup, but now connected up with the rest of the Abbasids. There is no reason why the Abbasid line should not have continued in Constantinople, but instead they disappear from history. I do not know whether they died out, the Ottomans exterminated them, or they just disappeared into obscurity.Below we see Islam in the year 1000 AD. The days of secular authority of the Abbasid Caliphs are now gone. The Caliphs are dominated by the Buwayid princes. The center of Islamic power and culture now seems to be in Egypt, with the Caliphate of the Shi'ite Fatimids. The Fatimids even control the sacred cities of Mecca and Medina. Representing Orthodoxy, the Omayyads in Spain have also declared a Caliphate. In the East, we now have the advent of the Turks, with the Ghaznawids beginning their inroads into India. This will permanently introduce Islam into India, even as these Turkish states mean the disappearance of Iranian people from Central Asia.THE IDRISID CALIPHS OF MOROCCO, 789-985 ADIdris I789-791Idris II791-828Muh.ammad al-Muntas.ir828-836'Ali I H.aydara836-849Yah.ya I849-863Yah.ya II863-866'Ali II866-?Yah.ya III al-Miqdam al-Jut.i?-905Yah.ya IV905-925Tributary to Fatimids, 917al-H.asan al-H.ajjam925-938al-Qasim Gannun938-948Ah.mad Abu'l-'Aysh948-954al-H.asan954-974,985Annexed by Fatimids, 985The Rustamids of Algeria, 778-909 AD'Abd ar-Rah.man778-788'Abd al-Wahhab788-824Aflah.
