Wars do not always begin with gunfire. Often, they start with trade. This book investigates how economic coercion—through sanctions, boycotts, and embargoes—has served as both a weapon and a provocation throughout history. From the naval blockades of the 19th century to oil embargoes and modern financial restrictions, "Sanctions, Boycotts and Embargoes" traces how pressure meant to prevent conflict can instead escalate it. Drawing on diplomatic archives, case studies, and economic data, it reveals how nations interpret financial measures as threats to sovereignty, prompting retaliation rather than restraint. The book exposes the thin line between deterrence and provocation, showing that economic warfare often reshapes alliances, destabilizes regions, and sets the stage for open conflict. It is a measured study of how money, not arms, can ignite global crises.
