Boxwallahs were small-scale travelling merchant peddlers in India. They were known as boxwallahs because of the large boxes in which they carried their merchandise (usually clothes and costume jewelry), though the term has been known to be applied to any traveling peddler and also to people involved in business and commercial activities (as opposed to "babus" or civil servants). Boxwallahs, the peddlers with boxes, were a common sight in the streets of Delhi and other north Indian cities from about 1865 to 1948. Boxwallah English was the commercial and trade English that Englishmen used when interacting with Indians (traders) during the British Raj.
The Boxwallah is also the title of an ITV Playhouse TV film that aired on 31 July 1982 and starred Leo McKern and Rachel Kempson.
