as Bophuthatswana, better known as the North West Province. From 1999 to 2001, he again studied in the North West Province, looking at occult-related violence. He researched this topic for 15 months. Then from 2002 to 2001, he studied crime and policing in this area. During 2005–2010 he researched the Tswana and San people and how ethnic identity and cultural property are becoming commoditised. Comaroff joined the American Bar Foundation in 1991 as a research fellow until 2012. In 2012, he and Jean Comaroff took teaching positions at Harvard University. He is no longer an affiliated scholar at the American Bar Foundation. Since 2009, Comaroff has worked on the project Ethnicity Inc., follow-up research being conducted in connection with the Comaroffs' book Ethnicity Inc. The project focuses on why ethnic groups have become increasingly like corporations, why culture has become more like intellectual property, and what about the contemporary world has made it that way. The Comaroffs published a book, Theory from the South, based on research conducted in South Africa. John and Jean Comaroff spent 34 years teaching at the University of Chicago. Research interests Witchcraft has been a topic of interest for the Comaroffs since 1969. The Comaroffs became particularly interested in this phenomenon after they returned to South Africa in the 1990s, shortly after apartheid had ended in South Africa. Global capitalism also serves as a topic of interest for both Comaroffs. They published Ethnicity Inc. (2009), which focuses specifically on the topic of global capitalism. They have also expressed an interest in the concept of lawfare, specifically how the law has been used to inflict violence indirectly by using the law to benefit oneself at the expense of others. This concept is used in their book Law and Disorder in the Postcolony (2006) in an analytical sense. In their book, Of Revelation and Revolution, the Comaroffs look closely at hegemony. Their definition states, "We take hegemony to refer to that order of signs and practices, relations and distinctions, images and epistemologies – drawn from a historically situated cultural field – that come to be taken for granted for as the natural and received shape of the world"(Comaroff, 1991). Comaroff has also been a lecturer in social anthropology at the University of Wales (1971–1972), University College of Swansea (1971–1972), and the University of Manchester (1972–1978). He was also a visiting professor at the University of California Riverside
