There is no doubt that few symbols convey a country's identity as strongly and explicitly as its national flag. From the battlefields of antiquity to today's diplomatic ceremonies and sporting competitions, national flags are a way of uniting history, culture, and visual symbolism.
There are almost 200 countries in the world recognized by the United Nations, each with its own national flag. In such a diverse world, even for those most knowledgeable about geopolitics and international relations, it is impossible to know the history behind each of these flags. Or is it?

A Symbol That Tells a Story
More than just pieces of colorful fabric fluttering in the wind, flags tell stories of peoples, achievements, and the ideals of one or more generations who inhabited a particular territory. The first flags emerged as authentic instruments of visual communication, allowing armies to be identified from a distance, for example. Over time, they evolved to represent historical events, values, religions, or visions of the future.
The origin of flags dates back to ancient times, even before they were used as symbols of countries. Civilizations such as the Egyptians, Romans, and Chinese already used banners and insignia to identify armies and leaders in the midst of battles. Over the centuries, especially in the Middle Ages, the use of flags expanded: kingdoms and empires adopted specific coats of arms and colors to represent dynasties, families, and political alliances.
Red with a white cross, the flag of Denmark, known as “Dannebrog,” is considered the oldest flag in the world, dating back to 1219.
However, the concept of the national flag as we know it today only began to take shape in the 17th and 18th centuries, a period marked by the consolidation of modern states, such as what happened after the French Revolution. From that moment on, flags began to represent not only monarchs, but also peoples and ideals.
In the 20th century, during the two World Wars, national flags were instruments of mobilization, pride, and patriotism. Each color carried with it a promise of freedom and sovereignty. After 1945, with the creation of several new states and the decolonization of various territories in Africa and Asia, national flags multiplied, incorporating colors and symbols linked to local culture and history.
A man's country is not just a certain area, mountains, rivers, or forests, but rather a principle, and patriotism is loyalty to that principle.

A Symbol in Constant Evolution
Despite their ancient origins, flags are more relevant than ever in the 21st century. They are displayed not only during official and diplomatic ceremonies but also at major international sports events such as the Olympics and the World Cup. Flags carry deep symbolic and emotional weight. In moments of national pride, a simple piece of cloth can unite entire populations around a common purpose.
In international relations, raising or lowering a flag remains a powerful act, signaling alliances, ruptures, sovereignty or solidarity. In the digital age, the concept of a flag has expanded. Beyond national and organizational flags such as those of the UN or EU, new emblems have appeared to represent causes and collective identities, like the rainbow flag for LGBTQIA+ pride, the peace flag or environmental banners calling for sustainability.
These new symbols show that even as the world changes and the concept of nation evolves, the human need for belonging and representation remains deeply rooted.
