Abdullah, died in 1857 and a series of succession disputes ensued. Unhappy with the abuse and favouritism of various royalties, rival Malay camps took sides with one or the other of the two great Chinese secret societies present in there at the time. Long Jaafar established and developed his administrative centre at Bukit Gantang and made Kuala Sungai Limau at Trong the principal harbour of the Larut Settlement. In 1857 Long Jaafar was succeeded by his son Ngah Ibrahim. Sultan Jaffar Muazzam Shah presented an acknowledgement letter to Ngah Ibrahim on 24 May 1858. This letter was signed by Sultan Jaffar, Raja Muda Ngah Ali and the Raja Bendahara of Perak. In the time of Ngah Ibrahim the Chinese increased in number and by early 1860 two large groups were formed by the Chinese, the "Five Associations" whose members worked in the mines of Klian Pauh and the "Four Associations" whose members worked in the mines of Klian Baharu. Mining rights were given to the Hakka "Five Associations" or Go-Kuan (五館 or 五群) and the Cantonese "Four Associations" or Si-Kuan (四館). Chung Keng Quee (鄭景貴) was leader of the Hakka Go-Kuan and the Hai San (海山) society that they belonged to, and began to operate his tin mines in Larut in 1860. Larut was destined to be plagued by four major wars between members of both the Cantonese Go-Kuan Ghee Hin Society (義興私會黨) and the Hakka Hai San society. Many Hakka had fled China when the Taiping Rebellion broke out there and found work in the mines of Chung Keng Quee establishing his position over the mining area in Larut as leader of the Hai San from 1860 to 1884. The capital of Perak was moved from Bandar Baru (New Town) to Taiping after Datok Maharaja Lela assassinated the first British Resident of Perak Mr. James Wheeler Woodford Birch at Pasir Salak in 1875. In 1937, the capital of Perak was moved from Taiping to Ipoh. The town's mining industry continued to thrive; the country's first railway was built to transport tin from Taiping to Port Weld (now known as Kuala Sepetang) at the coast for export. The first train in Malaysia took its schedule on 1 June 1885. By 1900, an English language school, a newspaper, and the Perak Museum (the oldest in Malaysia) had been established. Although Taiping's economy declined with the dwindling tin deposits, tin mining still
