 Sultan Iskandar is reputed to have been a staunch disciplinarian, with willingness to occasionally voice personal opinions on governmental issues. On the personal side, subjects who have personally approached the Sultan in his later years described him as a person with a warm and generous personality. However, past critics had also argued that Sultan Iskandar was a person with a turbulent temper. These claims were made by citing records of past notorious incidents, which include an experience of being disinherited from being the Tunku Mahkota of Johor (or Crown Prince in English) by his father, in 1961, as well as a series of alleged criminal acts occurring between the 1970s and the 1990s which were published in the press and provoked widespread moral outrage within the Malaysian public.
