The 50 paintings, dated between 1760 and 1886, were assembled by Greig over 45 years of research.
The collection spans Indian and European artists, including Sita Ram, Ghulam Ali Khan, Johan Zoffany, Rudolf Swoboda, and the Daniell brothers, offering dual perspectives on colonial India.
Tate’s press release said the works will join the museum’s existing Anglo‑Indian holdings, enabling a broader narrative of British‑Indian artistic exchange.
Greig said he chose to donate the collection to ensure it remains a public resource, rather than a private one.
A free public display is slated for 2028 at Tate Britain, allowing visitors to confront a visual record of pre‑photographic colonial India.
