Lucknow became a central hub for this embroidery technique during Aurangzeb's reign in the 12th Century, when this imperial art form was encouraged under ruling Mughal beneficiaries. Their patronage encouraged Zardozi artists to spread throughout India. This distinguished style of traditional Indian embroidery has been practiced and passed on from generations, in various parts of Uttar Pradesh. Zardozi is the main source of income for artisans of Lucknow and other adjoining parts. These products are exported to foreign countries also. Zardozi embroidery is impressively ornamental and involves profound use of crusted gold thread work. Initially, the embroidery was done with pure silver wires and real gold leaves. However, today, craftsmen make use of a combination of copper wire, with a golden or silver polish, and a silk thread. In 2013 the Geographical Indication Registry (GIR) accorded the Geographical Indication (GI) registration to the Lucknow Zardozi – the world-renowned textile embroidery from Lucknow. The Zardozi products manufactured in areas in Lucknow and six surrounding districts of Barabanki, Unnao, Sitapur, Rae Bareli, Hardoi and Amethi.
