Muhammad IV al-Hadi (Arabic: محمد الرابع الهادي), commonly referred to as Hédi Bey (Arabic: الهادي باي ; 24 June 1855 in Le Bardo - 11 May 1906 in Carthage)[1] was the son of Ali III ibn al-Husayn and the fourteenth Husainid Bey of Tunis, ruling from 1902 until his death.[2] [3]
He was named Bey al-Mahalla (Heir Apparent) on 3 December 1898 and succeeded as Bey of Tunis on the day of his predecessor's death, 11 June 1902, at a ceremony in the throne room of the palace in Tunis, in the presence of the French resident.[4] [1] Before the French protectorate of Tunisia the Ottoman sultan had bestowed honorific military ranks on the Bey of Tunis and his Heir Apparent. Hédi Bey did not receive such an honour, but was instead made Divisional General of the Beylical Guard when he became Heir Apparent, and became Marshal on his accession.
Following a dispute in 1904 with the French Resident General Stephen Pichon over the dismissal of his Grand Vizier Mohammed Aziz Bouattour, he suffered a stroke which caused paralysis of his lower limbs. Shortly before his death, the first violent resistance to authority since the start of the protectorate took place in the Thala-Kasserine Disturbances.
He died in his palace at Carthage Dermech and was buried in the Tourbet el Bey mausoleum in the medina of Tunis. He was succeeded by his cousin Muhammad V an-Nasir.
