[4] Between school and university, Duggan went on holiday to Italy and explored the country on a Honda CB175 motorbike.

He once had his flat raided by the DIGOS, the Italian anti-terrorist and organised crime unit, because they suspected him of being a foreign subversive; however, he was not arrested or charged.

[5] He returned to the University of Oxford to complete a Doctor of Philosophy (DPhil) degree under the supervision of Mack Smith.

[7] Duggan began his academic career as a junior research fellow at Wolfson College, Oxford between 1983 and 1985.

[5] During this period, he assisted Mack Smith and Moses Finley with updating their A History of Sicily book; this revised version was published in 1986.

[6] His first major work, Fascism and the Mafia, grew out of his DPhil, and was published in Italian in 1986 and in English in 1989.

[9] Shortly before his death, Duggan had been appointed to a research professorship in the Department of History, Reading,[10] and had been elected as a Two Year Fellow at All Souls College, Oxford.

[4] In 2013 Duggan's book Fascist Voices (2012) was awarded the prestigious Wolfson History Prize.

[15] His doctoral supervisor and mentor, Denis Mack Smith, had been awarded the same prize 36 years earlier.
