The term Memon refers to a few Muslim ethnic groups from the western part of the Indian subcontinent, including Memons historically associated with Kathiawar (simply called Memons) and their descendants-speakers of the Memon language. It also can refer to Kutchi Memons and Sindhi Memons.
Sindhi, Gujarati origins
According to Anthovan, those Lohanas of Thatta who converted to Islam became Memons and were invited by Jarejho Roa Khanghar, ruler of Bhuj (1548–1584) to settle in Bhuj. It is from there that Kutchi Memons migrated to Kathiawar and Gujarat. Surat in Gujarat was an important trading center from 1580 to 1680 and Memons made their bounty there. Later, the Memons reached Bombay.
Subgroups of Memons from Kathiawar
Today, Memons are scattered throughout India but majority of them live in the port city of Karachi in Pakistan, with significant communities in the United Kingdom, Canada, USA, Bangladesh, Sri Lanka, UAE, Saudi Arabia, Tanzania, Botswana, Namibia, South Africa, Malawi, Kenya, Mauritius, Singapore, Australia and Burma. In Karachi today there is a community of Memon people from Bantva and their descendants known as Bantva Memons. Also another prominent category is Halari Memon who works under the banner of Halari Memon General Jama'at. Halari Memon is a group of several subcategories and are also the follower of Hanfi Muslim.
Memons are known for their involvement in business and philanthropy, with Memons having played a major part in the building of Pakistani industry, an increasing number of Memons are turning to professional occupations.
