Inside the palace:
I found this information written in a board inside the museum with the title: Mir Akbar Ali Khan Sikander Jah, Asaf Jah III:
Born: 11th November 1768 at Hyderabad. ( 1st Rajab 1182 Hijri)
Accession to the throne: 11th August 1803 at Hyderabad.
Died: 21st May 1829 at Hyderabad.
The third Nizam inherited a prosperous state. His succession was ratified by the Mughal emperor Shah Alam II and his father’s titles were also conferred upon him.
Sikander Jah recovered from the British the territories between Ajanta and the river Godavari- an area that included the whole of the mineral rich region of Berar. However, he continued to have close ties with the British.
To improve internal administration and to ensure just means of collecting revenue, Sikander Jah placed Europen officers in charge of his districts. This was to replace the earlier system of revenue collection by the wealthy farmers including Arab chiefs and sowcars.
Hyderabad enjoyed a new era of progress. In 1806, a large area north of the city was named Secunderabad after Sikander Jah. This area was to station 5000 troops of the British Garrison.
Secunderabad later became the largest British cantonment in India. As the cantonment grew rapidly many locals relocated there from the hustle of the walled city across the river Musi, thus creating the twin city of Secunderabad.
