Aga Khan I (; or, less commonly but more correctly (; ), was the title accorded to Hasan Ali Shah (; ; 1804 in Kohak, Iran – 1881 in Bombay, India ), the governor of Kirman, 46th Imam of the Nizari Ismaili Muslims, and prominent Muslim leader in Iran and later in the Indian Subcontinent.

The Imam Hasan Ali Shah was born in 1804 in Kahak, Iran to Shah Khalil Allah, the 45th Ismaili Imam, and Bibi Sarkara, the daughter of Muhammad Sadiq Mahallati ( d. 1815 ), a poet and a Ni ‘ mat Allahi Sufi.

He was succeeded by his eldest son Hasan Ali Shah, also known as Muhammad Hasan, who became the 46th Imam.

The Imam Hasan Ali Shah's mother decided to go to the Qajar court in Tehran to obtain justice for her husband's death and was eventually successful.

Those who had been involved in the Shah Khalil Allah's murder were punished and the Persian king Fath Ali Shah increased Hasan Ali Shah's land holdings in the Mahallat region and gave him one of his daughters, Sarv-i Jahan Khanum, in marriage.

Fath Ali Shah also appointed Hasan Ali Shah as governor of Qumm and bestowed upon him the honorific of Aga Khan.

Hasan Ali Shah thus become known as Aga Khan Mahallati, and the title of Aga Khan was inherited by his successors.

Until Fath Ali Shah's death in 1834, the Imam Hasan Ali Shah enjoyed a quiet life and was held in high esteem at the Qajar court.

Soon after the accession of Muhammad Shah Qajar to the throne of his grandfather, Fath Ali Shah, the Imam Hasan Ali Shah was appointed governor of Kerman in 1835.

Hasan Ali Shah managed to restore order in Kerman, as well as in Bam and Narmishair, which were also held by rebellious groups.

Hasan Ali Shah sent a report of his success to Tehran, but did not receive any compensation for his achievements.

Despite the service he rendered to the Qajar government, Hasan Ali Shah was dismissed from the governorship of Kerman in 1837, less than two years after his arrival there, and was replaced by Firuz Mirza Nusrat al-Dawla, a younger brother of Muhammad Shah Qajar.

Refusing to accept his dismissal, Hasan Ali Shah withdrew with his forces to the citadel at Bam.

When it was clear that continuing the resistance was of little use, Hasan Ali Shah sent one of his brothers to Shiraz in order to speak to the governor of Fars to intervene on his behalf and arrange for safe passage out of Kerman.

With the governor having interceded, Hasan Ali Shah surrendered and emerged from the citadel of Bam only to be double-crossed.

Hasan Ali Shah and his dependents were sent to Kerman and remained as prisoners there for eight months.

Hasan Ali Shah remained in Mahallat for about two years.

He managed to gather an army in Mahallat which alarmed Muhammad Shah, who travelled to Delijan near Mahallat to determine the truth of the reports about Hasan Ali Shah.

Permission was given, and Hasan Ali Shah's mother and a few relatives were sent to Najaf and other holy cities in Iraq in which the shrines of his ancestors, the Shiite Imams are found.

At the time of his arrival in Shahr-i Babak, a formal local governor was engaged in a campaign to drive out the Afghans from the city's citadel, and Hasan Ali Shah joined him in forcing the Afghans to surrender.

The British also negotiated the safe return of Hasan Ali Shah to Persia, which was in accordance with his own wish.

The government agreed to Hasan Ali Shah's return provided that he would avoid passing through Baluchistan and Kirman and that he was to settle peacefully in Mahallat.

Hasan Ali Shah was eventually forced to leave for Calcutta in April 1847, where he remained until he received news of the death of Muhammad Shah Qajar.

Although some of his lands were restored to the control of his relatives, his safe return could not be arranged, and Hasan Ali Shah was forced to remain a permanent resident of India.

While in India, Hasan Ali Shah continued his close relationship with the British, and was even visited by the Prince of Wales when the future King Edward VII was on a state visit to India.

The judgement was significant in that it legally established the status of the Khojas as a community referred to as Shia Imami Ismailis, and of Hasan Ali Shah as the spiritual head of that community.

Hasan Ali Shah's authority thereafter was not seriously challenged again.

Soon, a government force of 24, 000 men forced Hasan Ali Shah to flee from Bam to Rigan on the border of Baluchistan, where he suffered a decisive defeat.
