When Britain was trading opium with China, Baldeo Das Birla, who was an adopted son of Shiv Narayan Birla used this opportunity to engage cargo ships in partnership with other tradesmen to trade opium with China. In 1887, Baldeo Das moved to Calcutta to set up business.^[2]

In the book by his great-grandson, Yash Birla mentioned that Baldeo Das Birla was named Raja by the British. The book further states that both Baldeo and his wife were both simple people who were deeply religious and superstitious.^[3]

Baladeo Birla and his wife had four sons: Jugal Kishore, Rameshwar Das, Ghanshyam Das Birla, and Brij Mohan Birla.
