The treaty that united Poland and Germany in nineteen ninety-one

Published on June 17, 2026 | Translated from Spanish

In 1991, Poland and Germany signed a friendship treaty that buried decades of resentment after World War II. This agreement paved the way for Poland to join the EU and NATO, with German support. Today, free movement, school exchanges, and economic cooperation are a daily reality for millions of people, strengthening regional peace and prosperity.

Two hands shaking over an unfolded map of Central Europe, one holding a blue ink pen signing a document, the other pointing to a blurred border line between Poland and Germany, EU and NATO flags waving in the background over a landscape of green fields and connected highways, showing diplomatic cooperation during the 1991 treaty signing, photorealistic cinematic style, warm office lighting, rough paper texture, soft shadows, symbolism of economic union and lasting peace, historical action scene.

How integration boosted infrastructure and connectivity 🚄

Bilateral cooperation allowed for the modernization of transport corridors, such as the A2 highway connecting Berlin with Warsaw. Additionally, digital border management systems were implemented to streamline the transit of goods. In the energy sector, both countries collaborate on power grid interconnection projects, facilitating the trade of renewable energy. These technical advances reduce logistics costs and improve the efficiency of supply chains in the region.

The day Germans stopped being the enemy 🤝

Before the treaty, crossing the border was like negotiating with an internet troll: slow, confusing, and with a risk of losing patience. Now, Poles can go buy sausages in Berlin without being asked for their family tree. And Germans, for their part, discovered that pierogi are not an existential threat. In the end, peace only needed less bureaucracy and more shared food.
