On March 2, 1811, the Balubur Limbangan Regency was defeated by Governor General Herman W. Daendels (of the Dutch Colonial Army), and Regent Tumenggung Wangsakusumah II resigned. Balubur Limbangan Regency comprised 6 sub-districts: Balubur, Malangbong, Wanaraja, Wanakerta, Cibeureum and Papandak.
On February 16, 1813, a new Limbangan Regency was founded by Lt. Governor Thomas S. Raffles which became Garut Regency. RAA. Adiwijaya was the first Regent of Garut Regency. He governed from 1813 until 1821. He was well-known for his call of Dalem Cipeujeuh.
Administratively, Garut regency consists of 42 sub-districts and 419 rural districts with 2,173,623 people (51% male, 49% female). Garut constitutes the buffer land and hinterland for the development of Bandung Raja's territory. It has a strategic position and acts as the supplier for the needs of Bandung municipality and regency's populations.
Based on topology, Garut Regency is divided into two territories:
- Northern Garut consists of highlands which constitute the largest rice fields in Garut
- Southern Garut mostly consists of sloping land and twelve rivers which flow south, emptying into the Indian Ocean
Tourist resorts are present in Garut Regency, popular not only for coastal panorama and the sea but also because of craters and waterfalls. Lakes and a hot springs, supported by fresh, cool air, are much enjoyed by local tourist and foreign tourists. No wonder the Garut Regency was called "Swiss Van Java" in the Dutch Colonial Period.
Land fertility varies greatly because of influence by mountains, rivers and coastal lowlands. As a result, agricultural businesses are primarily plantation-based, as well as subsistence farming and animal husbandry, followed by forest resources.
