Khurasan and Transoxiana

The Persianate east between the fading of direct Abbasid rule and the Mongol arrival — Khurasan, Transoxiana and the lands the Oxus and Jaxartes drain. Dense with succession: slave-generals taking their masters' provinces, vassals swallowing overlords, governors inheriting the empire that appointed them.

The line below is a time axis. Position on it is date, so concurrency is visible: concurrent polities sit side by side rather than in sequence.

17 sourced edges run between this region and another, to Abbasid Caliphate, Buyid Confederation, Delhi Sultanate, Mongol Empire, Marwanid Emirate, Burid Emirate of Damascus, Uqaylid Emirate, Mirdasid Emirate, Sultanate of Rum, Nizari Isma'ili State, Emirate of Derbend, Kakuyid Dynasty, Artuqid Dynasty, Gahadavala Dynasty of Kanauj, Chahamana Dynasty of Ajmer, Chandela Dynasty of Jejakabhukti and Sena Dynasty of Bengal. Those are not drawn on this line — a thread that crossed regions would assert a sequence nobody cited — but they are on each polity’s own page.
