Ghaznavid High-Tin Bronze Jar - AMD.188, Origin: Central Asia, Circa: 963 AD to 1187 AD, Dimensions: 8.2" (20.8cm) high x 9.6" (24.4cm) wide, Collection: Islamic Art, Style: Ghaznavid, Medium: High-Tin Bronze. The Ghaznavids started as Turkish slave governors of the Samanids in the Afghanistan area around Ghazna, which became an important cultural centre under their rule. Due to the previous Persian influences, the Turkic Ghaznavids became fully Persianised. Shah Mahmud expanded their empire from India to Iran. The Ghaznavids lost Iran to the Seljuks, and much of Afghanistan to the Gurids who sacked Ghazna in 1151. The capital was moved to Lahore until it was captured by the Ghurids in 1186.
