The Treaty of Windsor

The Treaty of Windsor, signed in 1386, was an important agreement between England and Portugal. It established a strong alliance between the two nations, facilitating mutual support and military cooperation. The treaty ensured that England would assist Portugal against its enemies, while Portugal would reciprocate. This alliance helped Portugal secure its independence and trade routes during a time of conflict in Europe. The Treaty of Windsor laid the foundations for a long-lasting relationship, and it remains notable as one of the oldest diplomatic treaties still in force today.
