I found this information written in a board in the palace with the title: Mir Tahniyat Ali Khan Afzal ud Daula, Asaf Jah V:
Born: 11th October 1827 at Hyderabad. (30th Rabi Awal 1243 Hijri)
Accession to the throne: 18th May 1857 at Hyderabad (24th Ramzan 1273 Hijri)
Died: 26th February 1869 at Hyderabad (13th Ziqat 1285 Hijri)
The fifth Nizam ascended the throne in a turbulent year, 1857- the year of the “Sepoy Mutiny”, later known as the first war of Independence.
Guided by the administrative reforms initiated by Sir Salar Jung, the progress of the state continued. The administration of the dominion was further recognized under five Subas that mnaged the 16 districts of the state. This was a period of steady economic development when the revenue and judicial systems were reorganized and the telegraph and postal systems introduced. The first railway line of the state were laid, however, Afzal ud Daula was not entirely convinced of the benefits of the railways. He said, ” it would give the British simple access to my dominions and my relatives an easy method of escaping.”
A generous man, the Nizam, often gave food to the poor. Each year, in the holy month of Moharram, the pious Nizam donated large sums of money for a charitable cause. In 1861, during a severe drought, using resources from his treasury, he arranged to bring food to the State, thus saving many lives.
