Published in 1920 by pioneer historian John E. Rees, Oregon—Its Meaning, Origin and Application is a brief etymological tract dedicated to deciphering the heavily contested linguistic roots of the state's name. Expanding upon the speculative methodologies he applied to neighboring Idaho, Rees argues that "Oregon" derives from specific Native American phonetic roots, attempting to definitively anchor the title in regional Indigenous dialects rather than European cartographic errors. By weaving together regional folklore, early exploration accounts, and localized vocabulary, the monograph attempts to construct a seamless narrative of authentic native pedigree for the broader Oregon Territory. A keen insight drawn from the work is how early regional scholars felt compelled to anchor new geopolitical entities to an imagined, romanticized Indigenous past; by fiercely claiming a "pure" Native origin for the state's name, historians like Rees actively commodified Indigenous heritage to lend an air of ancient, natural legitimacy to a recently manufactured colonial government.
