Digvijaysinhji, a Jadeja Rajput, was born at Sadodar, Gujarat on 18 September 1895 during the British Raj, nephew of the famed cricketer K.S.

Commissioned as second lieutenant in the British Indian Army in 1919, Digvijaysinhji enjoyed a military career for over a decade.

[10] In 2016, 50 years after Jam Saheb's death, Poland's Parliament unanimously adopted a special resolution honouring Jam Saheb Digvijay Sinhji for his aid to Polish children refugees during World War II.

[11][12] A documentary titled "Little Poland in India" was made in collaboration of both Indian and Polish governments to honour the efforts of Maharaja Jam Sahib[13] and Kira Banasinska, who led the movement in India to rehabilitate Polish refugees.

On 7 March 1935 at Sirohi, Sir Digvijaysinhji married Maharajkumari Baiji Raj Shri Kanchan Kunverba Sahiba (1910–1994), second daughter of Maharajadhiraj Maharao Sri Sir Sarup Ram Singhji Bahadur, the Maharao of Sirohi.

The 2022 Indo-Polish war epic film The Good Maharaja (2022) depicted Digvijaysinhji Ranjitsinhji Jadeja.
