Abstract

This dissertation argues that corruption in twentieth-century Arizona flourished because the regulatory structures created during the Progressive era contained foundational vulnerabilities that were exposed and exploited by Sunbelt-era economic growth. While scholars have tended to treat Arizona’s corruption scandals as episodic, this study demonstrates that they were the predictable outcome of institutional weaknesses embedded at statehood. Covering Arizona’s political structures and identity from statehood in 1912 through the post-Bolles reform era ending in 1980, the dissertation focuses on institutional development while using Don Bolles’s investigations and 1976 assassination as a focal point. This study draws primarily on contemporary newspaper reporting, particularly Don Bolles’s investigations and the Arizona Project series, supported by government documents and archival collections, including the Arizona Attorney General’s Don Bolles investigative files, which the author processed as lead archivist. Analytically, it combines Robert Klitgaard’s “C = M + D – A formula,” Susan Rose-Ackerman’s principal-agent theory, and Arnold Heidenheimer’s typology of corruption perception to address the structural, individual, and cultural dimensions of corruption.

The dissertation’s findings move in sequence. Arizona’s Progressive constitutional design created mechanisms for public accountability but embedded vulnerabilities that would later be exploited. Mid-century Sunbelt growth activated those vulnerabilities, transforming structural weakness into active accommodation and institutional capture. Three case studies, specifically Ned Warren’s land fraud operations, Kemper Marley’s business and political network, and Emprise Corporation’s infiltration of Arizona racing, demonstrate how corruption operated through coordinated networks that Don Bolles investigated. The reforms that followed his death proved largely cosmetic, leaving the underlying structures intact and demonstrating that external accountability, particularly investigative journalism, had become the only check in a system whose internal oversight mechanisms were themselves compromised. By connecting Arizona’s Progressive constitutional moment to its postwar governance failures, the dissertation reframes Arizona’s corruption scandals as structural outcomes rather than episodic misconduct. It extends its implications to broader questions of accountability under rapid growth.
