Reflecting on what it means to be ‘global’, this issue of frieze examines the relationship between culture and colonialism: from the imperial provenance of many European museum collections to rethinking the Euro-American canon; from the use of technology and the prison system to control bodies, to the resurgence of nationalist sentiments and fears. Featured artists, curators and writers include Teresa Burga, Rey Chow, Aruna D’Souza, Ângela Ferreira, Natasha Ginwala, Hou Hanru, Simon Njami, Ngũgĩ wa Thiong’o and Trinh T. Minh-ha.
