Zaccaria Márton Leódr. Nemes, Zoltán2025-06-172025-06-172025-05-30https://hdl.handle.net/2437/391977This thesis explores the historical and legal dimensions of the territorial dispute between Venezuela and Guyana over the Essequibo region. It traces the origins of the conflict back to colonial times, analyzing competing claims stemming from Spanish exploration, Dutch settlement, and British inheritance. The paper examines how the uti possidetis juris principle and the 1899 arbitral award have shaped the legal arguments of both states. It also evaluates the resurgence of the dispute during Guyana’s independence, the discovery of oil, and Venezuela’s recent unilateral actions. The study culminates with an analysis of the case before the International Court of Justice, highlighting key legal doctrines such as the finality of arbitral awards and the right to self-determination. Ultimately, the thesis argues that the dispute is as much about law as it is about power, colonial legacy, and evolving international norms.66enGuyana, Venezuela, 1899, colonialism, ICJ, international court of justice, border, territorial dispute, border dispute,public international lawLawHozzáférhető a 2022 decemberi felsőoktatási törvénymódosítás értelmében.
