This paper draws on the concepts of ideological and implementational spaces (Hornberger, 2002) to understand how different actors, at different historical moments characterized by the emergence and development of multilingual policies, and at different layers of the language planning and policy onion (Ricento & Hornberger, 1996), have sought to carve up, fill in and re-imagine spaces for the inclusion of Indigenous languages in Peru. Following a historical-textual analysis, I offer a historical and contemporary analysis of four instances of multilingual policy negotiation, addressing their contributions and shortcomings as well as pointing to areas of future research. Implications are offered for language policy and planning research and practices that seek to promote linguistic and cultural diversity for all.
