the 19th century, during which time Persian influence was dominant; and the "Modern School", which came into being as a result of the Western impact. According to Gibb in the introduction (Volume I): The Saljuqs had, in the words of the same author: Persianate culture of South Asia In general, from its earliest days, Persian culture was brought into the Subcontinent (or South Asia) by various Persianised Turkic and Afghan dynasties. South Asian society was enriched by the influx of Persian-speaking and Islamic scholars, historians, architects, musicians, and other specialists of high Persianate culture who fled the Mongol devastation. The sultans of Delhi, who were of Turko-Afghan origin, modeled their lifestyles after the Persian upper classes. They patronized Persian literature and music, but became especially notable for their architecture, because their builders drew from Irano-Islamic architecture, combining it with Indian traditions to produce a profusion of mosques, palaces, and tombs unmatched in any other Islamic country. The speculative thought of the times at the Mughal court, as in other Persianate courts, leaned towards the eclectic gnostic dimension of Sufi Islam, having similarities with Hindu Vedantism, indigenous Bhakti and popular theosophy. The Mughals, who were of Turco-Mongol descent, strengthened the Indo-Persian culture, in South Asia. For centuries, Iranian scholar-officials had immigrated to the region where their expertise in Persianate culture and administration secured them honored service within the Mughal Empire. Networks of learned masters and madrasas taught generations of young South Asian men Persian language and literature in addition to Islamic values and sciences. Furthermore, educational institutions such as Farangi Mahall and Delhi College developed innovative and integrated curricula for modernizing Persian-speaking South Asians. They cultivated Persian art, enticing to their courts artists and architects from Bukhara, Tabriz, Herat, Shiraz, and other cities of Greater Iran. The Taj Mahal and its Charbagh were commissioned by the Mughal emperor Shah Jahan for his Iranian bride. Iranian poets, such as Sa’di, Hafez, Rumi and Nizami, who were great masters of Sufi mysticism from the Persianate world, were the favorite poets of the Mughals. Their works were present in Mughal libraries and counted among the emperors’ prized possessions, which they gave to each other; Akbar and Jahangir often quoted from them, signifying that they had imbibed them to a great extent. An autographed note of both Jahangir and Shah Jahan on a copy of Sa’di's Gulestān states that it was their most precious possession.
