[4] The mahal of Sultanpur provided a force of 7,000 infantry and 200 cavalry to the Mughal army and was assessed at a tax value of 3,832,530 dams.

[4] The rest of Baraunsa then belonged to the small mahal of Bilahri, which supplied a military force of 2,000 infantry and 50 cavalry and was assessed at 815,831 dams.

[4] The two mahals of Kishni and Sathin (or Satanpur) were also in the sarkar of Awadh; they remained separate entities until 1750, when they were amalgamated into the pargana of Jagdishpur.

[4] Two mahals in the Lucknow sarkar would later form part of Sultanpur district: Amethi and Isauli.

[4] In Akbar's time, Manikpur also had two mahals in the present district: Jais, which was broken up beginning sometime before 1775, and Kathot, which as mentioned above covered the southern parts of pargana Miranpur.

[4] Sultanpur district remained split between the two subahs of Awadh and Allahabad until the late 1700s, when the latter was finally broken up.

[4] Nawab Saadat Ali Khan II enacted an administrative reform that replaced the subahs and sarkars with new divisions, called nizamats and chaklas.

[4] Among the more significant nizams were Sital Parshad (in office 1794–1800), Mir Ghulam Hussain (1812–14 and 1818–23), Raja Darshan Singh (1828–34 and 1837–38) and his son Raja Man Singh (1845–47), and Agha Ali Khan (the final nazim, in office from 1850 to 1856).

The effect of this change is shown in the table below as "new boundaries" - it does not take account of Baldirai sub-district, which did not exist at the time of the 2011 census.

[10] At the time of the 2011 Census of India, 70.03% of the population in the district spoke Hindi, 25.38% Awadhi and 4.35% Urdu as their first language.
