Sir Streynsham Master was an English colonial administrator who was one of the 17th-century pioneers of the English East India Company. He served as the Agent of Madras from 27 January 1678 to 3 July 1681, and is credited with having introduced the first administrative reforms in the Madras Government. He banned sati and prohibited the burning of a Hindu widow in 1680 in what is the first official British response to sati. He made English the sole official language and language of court in the Madras Presidency, replacing the Portuguese, Tamil and Malayalam languages.

Sati was a historical practice in Hindu communities in which a widow sacrifices herself by sitting atop her deceased husband's funeral pyre. Although it is debated whether it received scriptural mention in early Hinduism, it has been linked to related Hindu practices in the Indo-Aryan-speaking regions of India. Greek sources from around 300 BCE make isolated mention of sati, but it probably developed into a real fire sacrifice in the medieval era within the northwestern Rajput clans to which it initially remained limited, to become more widespread during the late medieval era.
