ICREA Research Professor Sandra Montón Subías exposes how Archaeology has come a long way from its origins as a colonial discipline to a more recent self-criticism and scrutiny in the wake of anti, post- and de-colonial thought. Beyond archaeologists' explicit unapologetic collaboration with colonialism during the 19th and most of the 20th centuries, an exploration of the effect of colonialism in archaeology reveals a myriad of other aspects in which archaeology became deeply entangled with what at first sight could be considered as a mere political and economic practice. Her own archaeological projects in the Mariana Islands (western Pacific) and the history of archaeological practice are brought to illustrate some of the issues raised.
