Vietnamese History and Maritime Law

Vietnamese History and Maritime Law: An Integrated Overview

Understanding Vietnam’s rich historical legacy and its modern maritime legal framework is essential for anyone studying Southeast Asian history, international law, or regional geopolitics. This course combines key events, notable figures, and fundamental legal concepts that shape Vietnam’s national identity and its claims in the East Sea (also known as the South China Sea).

1. National Heroes in Folk Tradition

Vietnamese folk riddles often embed references to celebrated patriots, preserving their memory across generations. One such riddle mentions the phrase "Bao giờ hết có mước Nam", which directly points to a national hero.

• Correct Answer: Nguyễn Trung Trực
• Other options such as Trương Trụ, Nguyễn Hữu Huân, and Võ Duy Dương, while important in their own right, are not linked to this particular riddle.

Nguyễn Trung Trực (1839‑1868) is renowned for his daring naval attacks against French forces, especially the famous Battle of the Đà Nẵng River. His legacy illustrates the intertwining of cultural expression and resistance.

2. The French Attack on Hanoi – 25 April 1882

During the French colonial expansion, the imperial capital of Hanoi faced a decisive assault on 25 April 1882. The defense was led by a prominent official:

• Correct Answer: Tổng đốc Hoàng Diệu
• Other figures such as Tổng đốc Nguyễn Tri Phương, Nguyễn Trung Trực, and Trương Định played crucial roles in different battles but were not in command on that day.

Hoàng Diệu, the governor of Hanoi, famously chose to fight to the end rather than surrender, symbolizing the steadfast spirit of the Vietnamese court against foreign aggression.

3. Foundations of the 1884 Treaty of Pa‑tơ‑nốt

The 1884 Treaty of Pa‑tơ‑nốt, a pivotal agreement that solidified French control over Vietnam, was not created in isolation. It built upon two earlier treaties:

• Nhâm Tuất (1862) – the first major concession after the French capture of Saigon.
• Giáp Tuất (1874) – a subsequent treaty that expanded French influence in the central and northern regions.

The Hắc‑măng treaty of 1883, though significant in other contexts, does not serve as a direct predecessor to the 1884 agreement.

Mnemonic: Remember “N‑G” – Nhâm (1862) + Giáp (1874) = New Ground for Pa‑tơ‑nốt. Visualizing the letters “N” and “G” as a new guide helps retain the connection.

4. Defining "Nội Thủy" in Vietnamese Maritime Law

Vietnam’s maritime zones are defined by specific legal terminology. The term "nội thủy" refers to:

• Correct Description: The waters that are directly adjacent to the coastline, lying inside the baseline (đường cơ sở) and forming part of Vietnam’s sovereign territory.
• Incorrect options describe zones outside the baseline, such as the territorial sea (200 nautical miles) or the exclusive economic zone (12 nautical miles from the baseline).

This definition is crucial for understanding Vietnam’s claims over its coastal waters and the legal basis for resource exploitation.

5. The Most Comprehensive Late‑19th Century Reformist

During the late 1800s, several Vietnamese intellectuals proposed reforms to modernize the nation. Among them, the most extensive and forward‑thinking plan came from:

• Correct Answer: Nguyễn Trường Tộ
• Other reformists like Trần Đình Túc, Nguyễn Lộ Trạch, and Nguyễn Huy Tế contributed valuable ideas but did not produce a proposal as all‑encompassing as Nguyễn Trường Tộ’s.

Nguyễn Trường Tộ advocated for educational reform, legal modernization, and the adoption of Western technology, laying groundwork for future national development.

6. Facts About the East Sea (Biển Đông)

The East Sea, a strategically vital body of water, possesses several well‑documented characteristics. Identify the false statement among the following:

• It is a semi‑enclosed sea – true.
• It shares maritime borders with China, Myanmar, the Philippines, and Brunei – true.
• Its area is about 3.4 million km² – true.
• False Statement: It is the smallest sea in the world.

In reality, the East Sea is one of the largest semi‑enclosed seas, far exceeding many other regional seas in size.

7. The Role of the "Đường Cơ Sở" in Maritime Delimitation

In international maritime law, the đường cơ sở (baseline) serves a specific purpose:

• Correct Function: It acts as the reference line from which the breadth of all other maritime zones—territorial sea, contiguous zone, exclusive economic zone, and continental shelf—is measured.
• It does not indicate the deepest point of the continental shelf, nor does it solely mark the 12‑nautical‑mile limit.

Understanding baselines is essential for interpreting Vietnam’s maritime claims and for negotiating boundaries with neighboring states.

8. Treaties Completing the French Colonial Conquest

The final phase of French domination over Vietnam was sealed by a specific pair of treaties:

• Correct Pair: The Hắc‑măng treaty (1883) and the Pa‑tơ‑nốt treaty (1884).
• Other combinations, such as Giáp Tuất with Pa‑tơ‑nốt or Nhâm Tuất with Hắc‑măng, do not represent the concluding agreements.

These two treaties together marked the end of Vietnamese sovereignty and the full integration of the country into French Indochina.

9. Synthesis: Connecting History and Maritime Law

Vietnam’s historical narrative and its contemporary maritime legal framework are deeply intertwined. The legacy of national heroes like Nguyễn Trung Trực and reformers such as Nguyễn Trường Tộ informs modern assertions of sovereignty, especially in contested waters like the East Sea. By recognizing the legal foundations—baselines, maritime zones, and historic treaties—students can appreciate how past events shape present‑day policy and international relations.

10. Key Takeaways for Review

• Nguyễn Trung Trực is the hero referenced in the folk riddle about "Bao giờ hết có mước Nam".
• Hoàng Diệu commanded the defense of Hanoi on 25 April 1882.
• The 1884 Treaty of Pa‑tơ‑nốt rests on the Nhâm Tuất (1862) and Giáp Tuất (1874) treaties.
• "Nội thủy" denotes waters inside the baseline, forming part of Vietnam’s sovereign territory.
• Nguyễn Trường Tộ proposed the most comprehensive reform in the late‑19th century.
• The East Sea is not the smallest sea; it is a large semi‑enclosed sea covering about 3.4 million km².
• The baseline (đường cơ sở) is the reference line for measuring all maritime zones.
• The Hắc‑măng and Pa‑tơ‑nốt treaties completed the French colonial conquest of Vietnam.

By mastering these points, learners will be equipped to analyze Vietnam’s historical resilience and its strategic maritime posture in the 21st century.
