This work examines the sinking of Titanic as a systemic failure rather than an isolated maritime accident. Drawing on the United States Senate Inquiry, the British Wreck Commissioner's Report, contemporary documentation, and vetted modern research, it analyzes how class structure, labor roles, and institutional assumptions shaped survival outcomes. Particular attention is given to third-class passengers and crew members, including immigrant communities whose experiences have historically been marginalized in popular narratives. The book also addresses the legacy of the disaster, tracing how regulatory reforms emerged-and where structural inequalities remained unaddressed. Written in a restrained, evidence-based style, this volume contributes to social and labor history, migration studies, and disaster analysis. It is suitable for general readers, libraries, and academic collections seeking a non-sensational, human-centered examination of Titanic and its aftermath.
