Isami was born in 1311, possibly in Delhi. His father's name was 'Izz ul-Din 'Isami. His ancestor Fakhr Malik Isami had migrated from Baghdad to India during the reign of Iltutmish. In 1327, the Delhi Sultanate ruler Muhammad bin Tughluq decided to move his capital from Delhi to Daulatabad in Deccan region. Several residents of Delhi, including Isami's family, were ordered to move to Daulatabad. His 90-year-old grandfather died during this journey.
In Bahman Shah's service
At Daulatabad, Isami was appalled with what he perceived as Tughluq's misdeeds and tyranny. At one point, he decided to migrate to Mecca, but he was determined to write a history of Muslim rule in India before leaving the country. He aspired to emulate the famous Persian poet Ferdowsi, who wrote Shahnameh, an epic poem outlining the history of Persia. Qazi Bahauddin of Daulatabad introduced him to Ala-ud-Din Bahman Shah, who had rebelled against Tughluq. Bahman Shah, who established the independent Bahmani Sultanate in the Deccan region, became Isami's patron. Isami thus became the earliest panegyrist at the Bahmani court. Under the patronage of Bahman Shah, he started writing Futuh-us-Salatin in 1349. Isami claims to have composed its 12,000 verses in 5 months. According to him, he started writing the book on 10 December 1349, and completed it on 14 May 1350. Nothing is known about Isami's life after this point.
''Futuh-us-Salatin''
The Futuh-us-Salatin is a history of Muslim rule in India until 1349-50. Isami also called it Shahnama-i Hind. According to Isami, his sources included anecdotes, legends, and reports by his friends and acquaintances. Unlike several earlier chronicles, the book's language is devoid of "rhetorical artifices and unpleasant exaggeration". The book begins with an account of the conquests of the Ghaznavid ruler Ghazni and the Ghurid ruler Muhammad. It then goes on to narrate the history of the Delhi Sultanate until 1349-50. The book also describes the early years of the establishment of the Bahmani Sultanate.
Historical reliability
Futuh-us-Salatin is written in masnavi style, and is not fully reliable for the purposes of history. It contains factual mistakes and omits several important events. In addition, Isami implies that the various historical events were pre-determined by divine will and destiny. He believed that the presence of spiritually powerfulSufi leaders affected the fortunes of a kingdom. For example, he attributes to the decline of the Delhi Sultanate to the death of the Sufi saintNizamuddin Auliya. Similarly, he claims that the Deccan region prospered because Burhanuddin Gharib and his successor Zainuddin Shirazi lived in Daulatabad. Isami is highly critical of Muhammad bin Tughluq. On the other hand, he calls his patron Bahman Shah as the rightful caliph. He claims that Tughluq forced the entire population of Delhi to move to Daulatabad, and that only 10% of the migrants survived the journey. Both these claims appear to be exaggerations. According to Isami, this unfortunate situation was a result of God's punishment to the corrupt Muslims. Despite these defects, Isami's book is a valuable source of information about the political history and social life of 14th century India.
