Khair al-Din led "the 'constitutional movement' that included luminaries such as Qabadu, Bayram V, bu Hajib, and Abi Diyaf, amongst a small group of reform-minded and Western-inspired figures. The 1861 constitution, the Muslim world's first such document, the legislative council and the civic bodies created on its basis all had the support of Khayr al-Din and his co-reformers."[26]
