Portugal vs Spain Timeline
The Portugal-Spain rivalry is defined by Europe’s oldest fixed border, established in 1297, yet its history is a dramatic saga far beyond a simple line on a map. From medieval battles for independence to a 60-year dynastic union, and from global colonial competition to parallel 20th-century dictatorships, their relationship has shaped the destiny of the Iberian Peninsula.
This timeline explores the decisive “matches” military, diplomatic, and cultural that transformed these two kingdoms, born from the same Reconquista, into distinct nations. Today, the rivalry has matured into a model of European partnership, where fierce football matches and shared management of the Schengen border coexist, proving that ancient divisions can evolve into modern, cooperative strength.
Early Years That Shaped the Tone: Forged in Battle and Treaty (1143-1385)
The defining tone of the Portugal-Spain rivalry was set not by a single event, but through a century-spanning struggle for sovereign existence. It began with the Treaty of Zamora (1143), where the Kingdom of León recognized Portuguese independence a diplomatic victory. The rivalry’s permanent character was cemented by the Treaty of Alcañices (1297), creating Europe’s oldest stable border.
Finally, the Battle of Aljubarrota (1385) was the decisive military climax, where Portugal, against all odds, crushed Castilian forces to secure its dynasty and sovereignty forever. This foundational era established a core dynamic: Portugal resisting absorption by its larger neighbor through resilient defense and strategic diplomacy.

Portugal vs Spain Today: A Model of European Partnership
Today, Portugal and Spain represent one of Europe’s most successful bilateral relationships, transformed from historical rivals into integrated partners. Within the European Union and Schengen Area, their border is a symbol of open cooperation, with deep economic ties, shared infrastructure projects, and constant cultural exchange.
Friendly rivalry persists primarily in football and tourism metrics, while governments coordinate closely on energy policy through the Iberian electricity market (MIBEL) and foreign affairs. The joint bid for the 2030 FIFA World Cup epitomizes this modern alliance. While distinct national identities remain proudly intact, the two nations now function as complementary halves of the Iberian Peninsula, leveraging shared history to build a common future.
Where Did It All Begin?
Long ago, the land wasn’t called Portugal or Spain. It was ruled by kings from the north and sultans from the south. Christian fighters were taking back land from Muslim rulers. This was the Reconquista. From this fight, a new kingdom appeared. In 1139, a brave count named Afonso won a big battle. He declared himself the first King of Portugal. This was the first big step in our Portugal vs Spain timeline. It set the stage for everything that followed.
The Battle That Saved Portugal
For over 200 years, Portugal fought to keep its freedom. Its bigger neighbor, Castile (which later became Spain), was very powerful. The most important moment came in 1385. The Castilian king invaded Portugal to take over. The Portuguese army was smaller. But they chose a great spot to fight near the town of Aljubarrota. They built clever defenses. They won a huge victory! This Battle of Aljubarrota guaranteed Portugal’s independence. It is the most celebrated win in Portuguese history. Without it, our Portugal vs Spain timeline might have ended long ago.
Shaking Hands on a Border
Before phones or maps, kings made deals in person. In 1297, two kings met. King Denis of Portugal and King Ferdinand IV of Castile signed the Treaty of Alcañices. They drew a line on the land. This line marked where one kingdom ended and the other began. That border is still there today! It is the oldest border in all of Europe. This treaty is a key point in the Portugal vs Spain timeline. It shows that sometimes, talking is better than fighting.
When Spain and Portugal Became One
Now for a crazy twist in our story. In 1580, the King of Portugal died without a clear heir. The powerful King Philip II of Spain was his nephew. Philip sent his army and said the Portuguese crown was his. For the next 60 years, Portugal was ruled from Madrid. Historians call this the Iberian Union. This period is a strange chapter in the Portugal vs Spain timeline. Portugal kept its own laws and money. But it had to follow Spain’s foreign wars. Many Portuguese people were not happy about it.
Portugal Fights Back and Wins Its Freedom
Enough was enough! On December 1, 1640, Portuguese nobles staged a quiet revolution. They went to the palace in Lisbon. They arrested the Spanish official in charge. Then they crowned a new Portuguese king, the Duke of Braganza. Spain was not happy. A long war began. It lasted 28 years! Finally, in 1668, Spain was tired of fighting. They signed the Treaty of Lisbon. They agreed that Portugal was, and always would be, a free country. This restoration is a proud moment in the Portugal vs Spain timeline.
Two Kings With Similar Rules
Let’s jump to the 1900s. Both countries had very tough leaders. Portugal had António de Oliveira Salazar. Spain had Francisco Franco. Both men were dictators. They believed in old-fashioned, strict rules. For a long time, both countries were closed off from the rest of Europe. They were poor and quiet. This part of the Portugal vs Spain timeline shows how they lived similar lives, side by side, but still separately. Their people couldn’t easily travel or share ideas.
The Wonderful Year Everything Changed
1974 and 1975 were magical years. In Portugal, people put flowers in soldiers’ guns. This “Carnation Revolution” brought democracy without violence. Next door in Spain, the old dictator Franco died. Spain began its own peaceful move to democracy. Then, in 1986, the biggest change happened. Both Portugal and Spain joined the European Economic Community on the same day! This modern chapter of the Portugal vs Spain timeline changed everything. They were no longer rivals on the edge of Europe. They were now a team at Europe’s heart.

From medieval battlefields to co-hosting the world’s biggest sports event. That’s real teamwork.
The Tiny Town That Still Causes Chatter
There is one little, quiet argument left. It’s about a small town named Olivenza (in Spanish) or Olivença (in Portuguese). Spain has controlled it since 1801. But Portugal has never officially said it’s Spain’s town. It’s a friendly dispute. You won’t see any soldiers there. Just normal people living their lives. It’s a curious footnote in the long Portugal vs Spain timeline. It reminds us that history leaves little marks that last for centuries.
