In the early 20th century, the Dutch East Indies government decided to relocate the capital from Batavia to Bandung. The idea was to separate the busy trading port and the commercial centre (Batavia) from the new administrative and political centre (Bandung). By the 1920s the plan to transfer the capital to Bandung was underway. As the city began the master plan of a new city, some government buildings, telecommunication (now Telkom Indonesia), railway networks (now Kereta Api Indonesia), a postal system (now Pos Indonesia), defence-military headquarters, and more were constructed and headquartered in Bandung. Some are still here to this day, such as Gedung Sate, which was planned as the government administrative centre of the Dutch East Indies. The plan, however, failed due to the Great Depression and the outbreak of World War II.
