This chapter focuses on four inter-connected forms of archaeology: public archaeology, community archaeology, activist archaeology, and engaged archaeology. While most sub-disciplines or fields in archaeology are named according to a time (e.g., medieval archaeology) or a type of environment (e.g., maritime archaeology), each of these sub-fields relates to a form of archaeological practice. Though all are linked by a remit to engage with the public, each has developed into a recognisable entity within archaeology. Public archaeology is primarily concerned with educating the public about archaeology (Matsuda and Okamura 2011: 4; Comer 2014: 6195), or with the protection of public heritage by governments (Merriman 2004a, 2004b), while community archaeology involves the community having a level of control over the project, among other factors (Marshall 2002; Moser et al. 2002; Olivier 2017). Activist archaeology is the use of archaeology to support direct action in support of, or in opposition, to a cause or issue (Zimmerman 2014: 19). Engaged archaeology is archaeology that is so embedded in the community that it is shaped by the needs and vision of community members. This may, or may not, involve direct action in relation to a social or political cause or issue.
