West Sumatra

The Minang lived in three valleys, each valley being ruled by a different leader. Their power reached as far as Batak regions and Rajang. The central Minang government lasted until the end of 18th century when the wealth of the gold mines was exhausted and the miners had to find other work. This work was found in the direction of coffee, salt, textiles and gambir (a superior vegetable tannin which proved to be an improvement on the original Chinese product). Islamic traders from the beginning of the Islamic reformation controlled the trade. Kings, Queens and other secular leaders who refused to follow the Paderi (religious leaders) were conquered during this troubled period in what became known as the Paderi wars. The Islamic university is still called Paderi.
In 1821, the Dutch secured their trade by making agreements with King Alam of Pagaruyung. The King gave them the Tanahdatar Valley in which they built Fort de Cock at Bukittingi. From there, they extended their power over the highlands.

The Paderi wars continued until 1837 at Bonjol, named after the most powerful Paderi leader, Imam Bonjol, where their power was broken.
From the beginning of the 20th century West Sumatra played an important role in modernizing Islam, especially in improving education for women. In the twenties many a well-educated student was frustrated by the lack of work. In 1926 the students, with the aid of the Communists, started a rebellion; many rebels were put into Dutch jails in New Guinea, Irian Jajah.

After the Second World War, during the independence struggle, Bukittingi briefly became the capital city of Indonesia; after the Dutch captured Sukarno it was the temporary refuge of the Government. On 1st. January 1950 Sumatra became a province of the newly independent Republic of Indonesia.
