Bygone Selangor by Rimba takes readers on a journey through the early history of Selangor during the British colonial era, from the late 19th to the early 20th century. This book vividly portrays the transformation of Selangor—from a land rich in natural resources to a key administrative and economic center in British Malaya. Drawing from colonial records and historical sources, the book explores the development of British administration, the rise of the tin mining industry, the construction of modern infrastructure, and the role of the Sultan and Malay nobility in adapting to changing times.
