Public Health Liberation (PHL) is an innovative general theory of public health aimed at accelerating health equity. This paper provides a rich synthesis of philosophical traditions, novel theories, and approaches to establish the basis for a new public health transdiscipline. The authors argue that the "public health economy" as a single analytic lens elucidates the contradictions and tensions that reproduce vast health inequity. Authored by a majority of Black women, community experiences and perspectives are a major strength of this paper because they draw upon leadership experiences with contemporary issues.

The authors begin by describing their background in public health advocacy and by demonstrating the need for PHL using lead-contaminated water crises from Flint, Michigan and Washington, DC. They discuss the benefits of horizontal and vertical integration that broaden public health discourse to include affected populations and that seek opportunities throughout the public health economy. Their philosophical and theoretical reasoning reinterprets and adopts disciplinary concepts in political theory, sociology, women's studies, African American emancipatory writing, anti-racism, and community psychology to form a culturally relevant worldview and cogent thesis. Several new constructs emerge that do not appear elsewhere in the literature - Gaze of the Enslaved, Morality Principle, liberation, illiberation, liberation safe spaces, public health realism, and hegemony. The authors use their ethical and theoretical assumptions to guide practice and community self-help. Public Health Liberation presents a major challenge to assumptions about public health effectiveness in addressing vast health inequity.
