Argentina and Brazil share a border and almost nothing else in how they chose to represent themselves. One flag was born out of a revolution, the other out of a change of government. Reading them side by side shows how much a design can reveal about the moment it was drawn.
What flags are for
A flag is a claim about who belongs. It gathers people under a common cause and works as a tool of political expression, which is why the same piece of cloth can appear at a celebration and at a protest in the same week.
The effect is easiest to notice at a sports event or an international summit, where a flag turns a crowd into a delegation.
Argentina: freedom and revolution
Argentina's flag emerged during the country's struggle for independence.
The blue and white date back to the 19th century and are said to stand for the sky and the clouds, a peaceful reading for a flag that came out of a war. The Sun of May at the center is the more pointed element: it marks the revolution of May 1810, the event that set independence in motion.

Brazil's flag comes from the late 19th century, when the country moved from monarchy to republic.
Green represents Brazil's forests, yellow the country's wealth in gold, and blue the sky with its stars. The motto across the middle, "Ordem e Progresso," comes out of positivist philosophy and states the ambitions of the new republic directly.

Set side by side, the two flags are doing different jobs. Argentina's is about rebellion and the fight for independence. Brazil's is about the country's natural wealth and its plans for the future. Same continent, same century, opposite emphasis.
Flags in diplomacy
At global events a flag becomes the face of a country and shapes how it is read from outside. That also makes flags contentious. Plenty of disputes in history have turned on the meaning or use of one, which is a strange amount of weight for a rectangle of cloth to carry.
Flags outside politics
Flags are not confined to poles. They appear in art, in media, on skin. Sports fans rally under them. Social movements adopt them and give them new meanings. An Olympics without flags is hard to picture at all.
