Khoja Shams-ud-din Gillani
"A great merchant, Khoja Shams-ud-din had his commercial establishments in Arabia & Persia.He received the "cartes" from the Portuguese to send his cargo ships to Mecca & Ormuz. In 1543, he sent three ships with commodities to Mecca and the Persian Gulf.
He had his brother, Abdul Jabbar, (Jaffer?ed.) in Arabia and there were great trading houses in the Red Sea. It was through this way that spices reached Cairo and other marts of the Mediterranean and finally various parts of the Continent (Europe ed.)
Thus, Shams-ud-din had a large network of international trade besides being one of the most important merchants of India collaborating with the Portuguese."

"Then, separate from these, there were important Isma’ili groups in coastal Gujarat which, according to tradition, all originated in the reign of Siddharaja (1094-1143). The Ismaili communities of Bohras and Khojas became larger in Gujarat than anywhere else in India, largely through conversion. Thanks to their connections with non-Muslim mercantile groups they were relatively successful in penetrating inland markets in western India as well, and they made their presence felt in many parts of the western Indian Ocean littoral."
