Since the Second Indonesian Youth Congress (held on 28 October 1928), the song “Indonesia Raya” (Great Indonesia) has been the most important song for the Indonesian people. The song, written by Wage Rudolph Supratman, was born at a time when Indonesia’s nationalist movement reached its peak. After a gradual 3-century long process of political and economic expansion, the Dutch colonizers had created a king-sized colony (containing roughly 17,000 islands) by 1928 that had taken the territorial boundaries of present-day Indonesia.
Due to its sheer vastness Indonesia contains a rich variety of cultures. Jakarta, Indonesia's capital city and the center of national politics and economics, is the melting pot of many such cultures. Starting from the colonial era - when the city was known as Batavia - people came from all corners of the archipelago to this developing megacity in search of a livelihood. As a consequence Jakarta currently has a population of almost ten million people (official figure). The distance from the area of cultural origin, however, has resulted in a fading of some cultural features (especially for those families that have been living in Jakarta for multiple generations), but it has been 'enriched' by a distinct urban culture.
