Kajang and its surrounding areas is a sub-district located within the Hulu Langat District in the state of Selangor. It is situated approximately 14 miles southeast of Kuala Lumpur. From Kuala Lumpur, Kajang can be reached by roads and rails. Kajang is also linked with Putrajaya, the National Administrative Centre and Cyberjaya, the National Multimedia City. On its west is situated Puchong town, Batu 3 and Klang. Basically Kajang consists of a number of Malay, Chinese and Indian settlements.
The village areas largely are populated by Malays. The Chinese settlement pattern is scattered around Kajang town. While rubber plantation areas are inhabited by settlers of Indian descents. If viewed from its topographical perspective, Kajang sub-District is located on a highland area which is approximately 76,250 cm from the sea level. Most of its landscape is hilly filled with mountains. Its flatlands can be found at river-basins such as Sungai Langat, Sungai Bangi, Sungai Semenyih and Sungai Chua. These areas are the early settlements explored in the Sub-district of Kajang.
The traditional Malay communities were known to open up settlements at river valleys or river basins especially in the valleys of Sungai Bernam, Sungai Selangor, Sungai Klang, Sungai Langat and Sungai Lukut. The definition of Selangor actually refers to the five river basins of these rivers. At the time the river was regarded as the connecting route for settlements. These river valleys were very fertile for farming and suitable for the farmers who were dependant on the land. They also carried out fishing activities.
The existence of Kajang also predicates upon these factors. There are a number of oral stories regarding the early explorations of Kajang Town and its surrounding areas. According to the elders, before the coming of outside settlers, Kajang and its surrounding areas were once the residence of the Orang Asli community from the Temuan sub-tribe. According to a local historian En. Shahabudin Ahmad, Kajang was explored in 1709 by the Orang Asli who were based in Klang. During that time, Klang was ruled by Orang Asli with their leader called Batin Seri Alam. This leader administered in Klang as at the time the forests were the administration centres for the Orang Asli community. Klang had its own territories administered by the 3 sons of Batin Seri Alam.
