Explanation:

In 1889, oil was discovered at Digboi giving rise to an oil industry. In this period Nagaon witnessed starvation deaths, and there was a decrease in the indigenous population, which was more than adequately compensated by the immigrant labor. Colonialism was well entrenched, and the tea, oil and coal-mining industries were putting increasing pressure on the agricultural sector which was lagging behind. The peasants, burdened under the opium monopoly and the usury by money lenders, rose again in revolt. Numerous raiz mels decided against paying the taxes. The protests culminated in a bayonet charge against the protesters at Patharughat in 1894. At least 15 were left dead and in the violent repression that followed villagers were tortured and their properties were destroyed or looted. In 1903, Assam Association was formed with Manik Chandra Baruah as the first secretary.
