In 1923, rural New England mill town Dover, New Hampshire, staged a Tercentenary pageant of extraordinary proportions to celebrate its "first" settlement. This public spectacle memorialized a specific, and deeply exclusionary, narrative of English settler colonialism, shaped by social anxieties of the post-First World War United States. Recent archaeological research has found possible remnants from this spectacle on a seventeenth-century site. In disturbing this site, the Tercentenary pageant appears to have disregarded actual significant material traces from the very era it aimed to memorialize--traces that offer distinct, fuller understandings of deeply nuanced Native-settler interactions in the Piscataqua River region. Dover's pageant is situated in a regional analysis of Native and Euro-colonial commemorative place-making of the early twentieth century, exploring how different communities pursued multivocal, monovocal, or other approaches in their performative engagements with the seventeenth century.
