Prior to 1874, the exchange of international mail was entangled in a web of conflicting bilateral agreements. Each nation navigated a complex system where transit fees depended on the specific route taken, creating significant friction for global commerce and communication. The lack of standardization regarding weights and rates rendered the process inefficient and costly.
The diplomatic landscape shifted decisively with the initiative of Heinrich von Stephan, a senior postal official from the German Empire. Recognizing the strategic necessity of reform, he convened an international conference in Switzerland. The resulting Treaty of Bern dismantled the old barriers, establishing the General Postal Union, known today as the Universal Postal Union. This agreement declared the member countries a single postal territory for the reciprocal exchange of letters.
The brilliance of this reorganization lay in its simplification of financial accounts. The treaty introduced the principle that each nation would retain the postage it collected, eliminating the need for tedious accounting between borders for ordinary mail. By standardizing rates and removing the burden of transit calculations, the union optimized the flow of information. This foundation of international cooperation ensured that mail could move freely, securing a stable framework that has endured through centuries of geopolitical change.
