The “Archipelagic Doctrine” is a legal principle wherein an archipelago is to be regarded as a single unit, such that the waters around, between, and connecting the islands of the archipelago, irrespective of their breadth and dimensions, form part of the internal waters of an archipelagic state, and are subject to its exclusive sovereignty. This is reflected in Part IV of the United Nations Convention on the Law of the Sea (UNCLOS) and enshrined in Article I of the Philippine Constitution.


Gaining acceptance of this principle as a doctrine of international law was a struggle that took decades, with the Philippines leading the charge, in order to preserve the territorial integrity of the Philippine archipelago through the inseparable unity of the land and water domain. Without the archipelagic doctrine, each island of the country would only have its own territorial sea and corresponding maritime zones, with the effect of allowing the waters beyond the territorial sea to become international waters thus dismembering parts of the Philippines from each other due to the breadth of the waters interweaving our islands.


The battle was fought by some of the best and the brightest of the Philippine foreign service, luminaries who are featured in this online exhibit, which shows that through the diplomatic efforts of the Philippines and other archipelagic states such as Indonesia, Fiji and Mauritius, the archipelagic doctrine overcame challenges and has earned its legal and international recognition in the UNCLOS.


In this online exhibit, witness the story of how the Philippines' advocated and fought to be acknowledged as an archipelagic State in the international community.
