1. The Foundation (1930)
In 1930, the Belgian government established the Régie des Télégraphes et des Téléphones (RTT), centralizing the nation’s communications infrastructure. This decisive move laid the foundation for modern connectivity in Belgium, an entity that would eventually evolve into the contemporary Proximus Group.
2. Development and Industrial Impact
Prior to 1930, telegraph and telephone services in Belgium were fragmented and struggled to meet the demands of a rapidly modernizing industrial economy. The creation of the RTT unified these vital services under a state monopoly, initiating a massive modernization program. The agency aggressively expanded the copper wire network, automated switching stations, and installed public telephones across urban and rural landscapes. This infrastructure survived the devastation of World War II and became the backbone of Belgium’s post-war economic resurgence.

4. Legacy
Privatized and rebranded as Belgacom in the 1990s, and later as Proximus, the organization remains Belgium’s largest telecommunications provider. Its origins in the 1930 RTT reflect a century-long commitment to connecting citizens and driving technological progress.
