The Marwari or Marwadi are an Indian ethnic group that originate from the Marwar region of Rajasthan, India. Their language, also called Marwari, comes under the umbrella of Rajasthani languages, which is part of the Western Zone of Indo-Aryan languages. They have been a highly successful business community, first as inland traders during the era of Rajput kingdoms, and later also as investors in industrial production and other sectors. Today, they control many of the country's largest media groups. Although spread throughout India, historically they have been most concentrated in Kolkata, Mumbai, Chennai, Delhi, Nagpur, Pune and the hinterlands of central and eastern India. Etymology The term Marwari once referred to the area encompassed by the former princely state of Marwar, also called the Jodhpur region of southwest Rajasthan in India. The Jodhpur region includes the present districts of Barmer, Jalore, Jodhpur, Nagaur, Pali and parts of Sikar. It has evolved to be a designation for the Rajasthani people in general but it is used particularly with reference to certain jātis that fall within the Bania community. The most prominent among these communities, are the Agrawals, Khandelwals, Maheshwaris and Oswals. It is possible that the association of the Marwari term with Jodhpur owes more to the high status of that place in pre-independence India. Dwijendra Tripathi believes that the term Marwari was probably used by the traders only when they were outside their home region; that is, by the diaspora. Anne Hardgrove also supports this argument, saying that the Marwari identity could only exist in the context of a diaspora who came from somewhere and that until they migrated they had no such designation. History Early origins Marwari traders have historically been migratory in habit. The possible causes of this trait include the proximity of their homeland to the major Ganges - Yamuna trade route; movement to escape famine; and the encouragement given to them by various rulers of northern India who saw advantages in having their skills in banking and finance. The pattern of Marwari migration became increasingly divergent following the decline in wars between Rajput kingdoms, which the Marwaris had helped to finance, and the decreasing influence of the community over the North Indian caravan trading routes that resulted from the British establishing themselves in the region. The changed focus of migration was also encouraged by the British, who established or patronised new trading routes and centres, as
