Mahmud of Ghazni frequently invaded the hills of Ghur which lay to the west of him, but never made any practical impression on the Ghuri tribespeople. In 1020, however, Mahomedans conquered Ghur effectually from Herat. About a century later (this is after the time of Idrisi, whose records we are following) a member of the ruling Ghuri family (Shansabi) was recognized as lord of Ghur, and it was one of his sons (Alauddin) who inflicted such terrible reprisals on Ghazni when he sacked and destroyed that city and its people. It was about this time (according to some authorities) that the kingdom of Bamian was founded by another member of the same family; but we find Bamian distinctly recognized as a separate kingdom by Idrisi a century or so earlier. From 1174 to 1214 Bamian was the seat of government of a branch of this family ruling all Tokharistan (Turkistan), during which period Seistan and Herat were certainly tributary to Ghur. Ghur then became so powerful, that it was said that prayers in the name of the Ghuri were read from uttermost India to Persia, and from the Oxus to Hormuz.
In 1214 Ghur was reduced first by Mahomedans from Khwarezm (Khiva), and shortly afterwards by Chenghis Khan and his Mongol hosts. About the middle of the thirteenth century, however, a recrudescence of power appeared under the Kurt (or Tajik) dynasty subject to the supreme government of the Mongols. Seistan, Kabul, and Tirah were then ruled from Herat as the capital of Ghur. Timur finally broke up Herat and Ghur in 1383, since which time its history has been as obscure as the geography of the region which surrounded it. Such in brief is the stormy tale of Ghur, and it leads to one or two interesting deductions. There was evidently constant and ready communication with Herat, Bamian, and Ghazni. The capital of Ghur must have been an important town, situated in a fertile and fairly populous district, which, although it was mountainous, yet enjoyed an excellent climate. It must have been a military centre too, with fortresses and places of defence. During its later history it is clear that Ghur was often governed from Herat, but in earlier mediæval days Ghur possessed a distinct capital and a separate entity amongst Afghan kingdoms, and was able to hold its own against even so powerful an adversary as Mahmud of Ghazni, whilst its communications were with Bamian on the north-east rather than with Kabul, which was then regarded as an "Indian" city. We can at any rate trace no record of a direct route between Ghur and Kabul.
In the twelfth century we read that the capital of Ghur was known as Firozkohi, which name (says Yule) was probably appropriated by the nomad Aimak tribe now called Firozkohi; but within the limits of what is now recognized as the habitat of the Firozkohi (i.e. the plateau which forms the basin of the Upper Murghab), it is impossible to find any place which would answer to what we know of the general condition of the surroundings and climate of the capital of Ghur, and which would justify a claim to be considered a position of commanding eminence. The altitude of the Upper Murghab branches is not more than 6000 to 7000 feet above sea-level, at which height the climate certainly admits of agriculture, but no place that has been visited, nor indeed any position in the valleys of the Upper Murghab affluents, corresponds in any way to what we are told of this capital.
If we look for the best modern lines of communication through Central Afghanistan we shall certainly find that they correspond with mediæval routes, fitting themselves to the conformation of the country. Central Afghanistan is open to invasion from the north, west, and south, but not directly from the east. The invasion of Ghur from Ghazni, for instance, must have been directed by Kalat-i-Gilzai, Kariut, and Musa Kila (in Zamindawar), to Yaman, which lies a little to the east of Ghur (or Taiwara). So far as we know there are no passes leading due west from Ghazni to the heart of the Taimani country.
From the south the Helmund and its affluents offer several openings into the heart of the Hazara highlands to the east of Taimani land, amidst the great rocky peaks of which the positions were fixed from stations on the Band-i-Baian. But there is no certain information about the inhabited centres of Hazara population; and from what we know of that desolate region of winter snow and wind, there never could have been anything to tempt an invader, nor would any sound commercial traveller have dreamt of passing that way from Seistan to Bamian and Kabul. The idea that Alexander ever took an army up the Helmund valley, and over the Bamian passes, must be regarded as most improbable in spite of the description of Quintus Curtius, who undoubtedly describes a route which presented more difficulties than are quite appropriate to the regular Kandahar to Kabul road. On the other hand, from Seistan by the Farah Rud there is a route which is open to wheeled traffic all the way to Daolatyar on the upper Hari Rud. Daolatyar may be regarded as the focus of several routes trending north-eastward from Seistan, with the ultimate objective of Bamian and the populous valleys of Ghur.
One of the chief affluents of the Farah Rud is now known as the Ghur, and we need look no farther than this valley for the central interest of the Ghur kingdom, although the exact position of the capital may still be open to discussion. Between the Tagao Ghur and the Farah Rud are the Park Mountains, which are almost Himalayan in general characteristics and beauty, with delightful valleys and open spaces, terraced fields, well-built two-storied wooden houses, pretty villages, orchards with an abundance of walnuts and vines trailing over the trees; the Ghur valley itself being broad and open with a clear river of sweet water in its midst. This is near its junction with the Farah Rud. Above this, for a space, the valley narrows to a gorge and there is no passing along it, whilst above the gorge again it becomes wide, cultivated, and well populated, and this is where the Taimani headquarters of Taiwara are found. Taiwara is locally known as Ghur, and may be absolutely on the site of the ancient capital, for there are ruins enough to support the theory. Beyond an intervening band of hills to the south are two valleys full of cultivation and trees, wherein are two important places, Nili and Zarni, which likewise boast of extensive ruins, whilst at Jam Kala, hard by, there is perched on a high spur above the road with only one approach, a remarkable stone-built fort. Yaman, to the east of Taiwara, in the Helmund drainage, is a permanent Taimani village. Here also are very ancient ruins, and the people say that they date from the time of Moses. At that time they say that cups were buried with the dead, one at the head and one at the foot of the corpse. Our native surveyor Imám Sharif saw one of these cups with an inscription on it, but was unable to secure the relic.
Nili and Zarni are in direct connection with Farah, with no inconvenient break in the comparatively easy line of communication; and they all (including Taiwara) are in direct communication with Herat, by a good khafila route (i.e. good for camels). But the routes differ widely, that from Herat to Taiwara by Farsi being more direct, whilst the route from Herat to Zarni by Parjuman (which is well kept up between these two places) passes well to the south. All these places, again, are connected with the Hari Rud valley at Khwaja Chist (the Ghur frontier) by a good passable high-road, which first crosses the hills between Zarni and Taiwara, then passes under the shadow of a remarkable mountain called Chalapdalan, or Chahil Abdal (12,700 feet high—about which many mysterious traditions still hover), over the Burma Pass into the Farah Rud drainage, thence over another pass into the valleys of the Tagao Ishlan, and finally over the Band-i-Baian into the Hari Rud valley at Khwaja Chist.
This is the route described by Idrisi as connecting Ghur with Herat, as we shall see. The Ghur district is linked up with Daolatyar and Bamian by the Farah Rud line of approach, or by a route, described as good, which runs east into the Hazara highlands, and then follows the Helmund. The latter is very high. There is therefore absolutely no difficulty in traversing these Taimani mountain regions in almost any direction, and the facility for movement, combined with the beauty and fertility of the country, all point unmistakably to Taiwara and its neighbourhood as the seat of the Ghuri dynasty of the Afghan kings.
The picturesque characteristics of Ghur extend southward to Zamindawar on its southern frontier, the valleys of the Helmund, the Arghandab, the Tarnak, and Arghastan—this is a land of open, rolling watersheds, treeless, but covered with grass and flowers in spring, and crowned with rocky peaks and ridges of rugged grandeur alternating with the rich beauty of pastoral fields. The summer of their existence is in curious contrast to the stern winter of the storm-swept highlands above them, or the dreary expanse of drab sand-dusted desert below. The route upstream to the backbone of the mountains, and so over the divide to the kingdom of Bamian, was once a well-trodden route.
Since so many routes converge on Daolatyar at the head of the Hari Rud valley, one would naturally look for Daolatyar to figure in mediæval geography as an important centre. It is not easy, however, to identify any of the places mentioned by Idrisi as representing this particular focus of highland routes. Between Ghur and Herat, or between Ghur and Ghazni, the difficulty lies in the number and extent of populous towns, any one of which may represent an ancient site, to say nothing of ruins innumerable. Between Taiwara and Herat we get no information from Idrisi till we reach Khwaja Chist on the frontier. He merely mentions the existence of a khafila road, and then he counts seven days' journey between Khwaja Chist and Herat, reckoning the first as "short."
