By bringing craftsmen from different conquered lands to his capital in Samarqand, Timur initiated one of the most brilliant periods in Islamic art. Timurid art and architecture provided inspiration to lands stretching from Anatolia to India. Though Timur's extensive empire itself was relatively short-lived, his descendants continued to rule over Transoxiana as leading patrons of Islamic art. Through their patronage, the eastern Islamic world became a prominent cultural center, with Herat, the new Timurid capital, as its focal point. Timurid rulers were sympathetic to Persian culture and lured artists, architects, and men of letters who would contribute to their high court culture.
Many Timurid princes were also prodigious builders—religious institutions and foundations such as mosques, madrasas, khanqahs (convents), and Sufi shrines were the main beneficiaries of their building programs ... Trademarks of the Timurid style were monumental scale, multiple minarets, polychromy tilework, and large bulbous double domes.
