General Nawab Sir Sadiq Muhammad Khan V Abbasi GCSI GCIE KCVO (Urdu: جنرل نواب صادق محمد خان عباسی; 29 September 1904 – 24 May 1966) was the 12th and final Nawab (ruler) of the state of Bahawalpur from February 1907 to October 1955, and then as a titular figure until his death in 1966.

When only two and a half, his father fell ill and died while at sea off the Aden coast, on 15 February 1907, leaving Sadeq as ruler of Bahawalpur.

At the age of 15, Sadeq fought in the Third Afghan War in 1919, was knighted in 1922 when he reached his majority and was invested with the throne two years later by the Viceroy of India, Rufus Isaacs, Lord Reading.

Bahawalpur state also had a separate mint to cast coins for its public and the facility remained intact until 1940.

The British Government established a Regency Council under the supervision of Maulvi Sir Rahim Bakhsh until the minor Nawab grew up as a young man.

The Viceroy of India, Lord Reading awarded total authority of the state administration to Nawab Sadiq Muhammad Khan (V) on 8 March 1924.

[2] Sir Sadiq continued his military career in the British Indian Army, which he had begun as a Lieutenant in 1921; by 1932 he was a Major, by 1941 a Lieutenant-Colonel, commanding troops in the Middle East during the Second World War.

[2] From the 1930s Sir Sadiq began regularly holidaying in England, purchasing Ardene and the surrounding woodland on the outskirts of Farnham, Surrey.

[citation needed] After the partition of India Nawab proved to be very helpful and generous to the government of Pakistan.

[2] At the time of partition, all the princely states of the subcontinent were given the choice of joining Pakistan or India or remaining independent.

To try to convince the Nawab to join India, Pandit Nehru went to him while he was in London and offered various incentives in this regard, but he did not accept them.

In 1955, an accord was signed between Sadiq Mohammad and Governor-General Malik Ghulam Muhammad, according to which the State of Bahawalpur would become part of the province of West Pakistan and the Nawab was to receive a yearly stipend, or privy purse, of 32 lakhs of rupees and was to keep the title of Nawab and its precedence both inside and outside Pakistan.
