Jayakarta became Batavia, then the world’s densest metro
Jakarta, Indonesia’s Special Capital Region, covers about 662 square kilometres on Java’s northwest coast—yet Greater Jakarta (Jabodetabek) exceeds forty million people, among the planet’s largest urban agglomerations. An alpha world city and ASEAN’s secretariat seat, it still floods, sinks, and waits for the legal move of capital functions to Nusantara.
Sunda Kelapa was a principal port of the Sunda Kingdom; Portuguese apothecary Tomé Pires knew it as Calapa. Islamic forces took it in 1527; the Sanskrit-rooted Jayakarta—“victorious deed”—entered European logs as Jacatra and kin. VOC officer Jan Pieterszoon Coen burned the royal seat in May 1619 and rebuilt Batavia, named for the Batavi, as Dutch Asia’s headquarters for more than three centuries. Canal silting and post-1730s disease pushed elites south to Weltevreden; the 1740 massacre of Chinese residents reshaped settlement toward Glodok.
Japan renamed the city Jakarta in 1942. Independence was proclaimed there on 17 August 1945; after revolutionary years with a temporary capital in Yogyakarta, Jakarta regained capital status in 1950. Sukarno’s nation-building—National Monument, Hotel Indonesia, Senayan, the Thamrin–Sudirman axis—prepared the 1962 Asian Games. Suharto’s New Order and later Reformasi decentralisation followed; residents first directly elected a governor in 2007. In 2022 law paved relocation to Nusantara in East Kalimantan, though presidential decree must still transfer functions.
Thirteen rivers, including the Ciliwung, cross a low alluvial plain from below sea level to about fifty metres. Subsidence from groundwater extraction and heavy buildings worsens coastal flood risk beside monsoon rains. No ethnic majority: Javanese, Betawi, Sundanese, Chinese Indonesians, and migrants mingle; Betawi culture itself fused local, Chinese, Indian, Arab, and European strands. Monthly means stay near 26–28°C, while the annual mean warmed about 1.6°C per century between 1866 and 2012.
