In international news, we often hear the term annexation . This term usually arises when there are territorial conflicts between countries, land disputes, or changes in national borders. But what exactly does annexation mean? Why is this act often considered controversial and even illegal under international law?
This article will discuss in full the definition of annexation, its history in world politics, and the major impact it has had on society and relations between countries.
Definition of Annexation
Simply put, annexation is the act of one country taking over another country's territory and making it part of its sovereignty . This process is usually carried out without the consent of the conquered party, making it different from the unification of territory through a legitimate agreement or referendum.
Under modern international law, annexation is considered illegal because it violates the principle of state sovereignty. However, throughout history, this practice has often been employed by powerful nations to expand their territory, control resources, or strengthen their strategic positions.
The Difference Between Annexation and Invasion

Many people often equate annexation with invasion. However, the two are distinct.
- Invasion is a military action to enter another territory to control or occupy it.
- Annexation is the next step, namely the formal annexation of the territory into the attacking country.
This means that not all invasions end in annexation. However, almost all annexations begin with invasion or political pressure.
History of Annexation in the World

Annexation is nothing new. From the time of empires to the modern era, this practice has been commonplace. Here are some notable examples:
- Annexation of Alsace-Lorraine (1871)
Following the Franco-Prussian War, Germany annexed the Alsace-Lorraine region from France. This annexation sparked long-standing tensions and was one of the causes of the outbreak of World War I. - Annexation of Hawaii by the United States (1898)
The Kingdom of Hawaii was officially annexed and made part of the United States. This event remains a matter of debate, particularly regarding the rights of Native Hawaiians. - Annexation of Austria by Nazi Germany (1938)
This event, known as the Anschluss , expanded the power of Nazi Germany in the lead-up to World War II. - Annexation of Kuwait by Iraq (1990)
Iraq under Saddam Hussein annexed Kuwait for economic and political reasons. This action sparked the Gulf War , in which an international coalition intervened to liberate Kuwait. - Annexation of Crimea by Russia (2014)
Russia claims that the Crimean people want to join its territory. However, the international community considers this action illegal and a violation of international law.
These examples show that annexation often triggers major conflicts and changes the political map of the world.
Reasons for Countries to Annex

There are several main reasons why a country carries out annexation:
- Politics and Power : expanding territory to show dominance on the international stage.
- Economy : the annexed territories are usually rich in natural resources or have a strategic position in trade.
- Defense and Security : controlling certain areas is considered important to protect the country from external threats.
- Identity and Nationalism : some countries claim certain territories as part of their history or national identity.
The Impact of Annexation on the World

Annexation has significant consequences for both the occupying and the occupied country. The annexed country or territory loses its right to self-government as its people are forced to submit to new laws and governments. Annexation often leads to armed conflict, both local and international, such as Iraq's annexation of Kuwait, which sparked the Gulf War.
Furthermore, communities in annexed territories often face humanitarian crises, including mass displacement, human rights violations, and the loss of cultural identity. Annexation is almost always rejected by the international community, leading to economic sanctions, political isolation, and prolonged diplomatic tensions. Furthermore, annexation redraws national borders and geopolitical maps, with impacts that can last for decades, even generations to come.
International Legal Perspective

Under international law, particularly the United Nations Charter, annexation without consent is considered a serious violation . The UN emphasizes the principle of sovereignty and the right of self-determination for every nation.
However, there are some cases where annexation is accepted through a formal agreement or a legitimate referendum. However, such cases are extremely rare.
Conclusion
Annexation is the unilateral act of one country to take over another country's territory and incorporate it into its sovereignty. Throughout history, this practice has often been carried out for political, economic, or defense reasons, but it almost always results in conflict and suffering.
From Alsace-Lorraine to Crimea, annexation has reshaped the world map and impacted relations between nations. In the modern era, international law rejects annexation as a legitimate means of territorial expansion. However, the practice still occurs and remains a sensitive issue in global politics.
Understanding what annexation is, its history, and its impacts allows us to be more critical in viewing international news. Because, behind every annexation, there's always a story of power, struggle, and the fate of the people affected.
