Why did Papuans start a long-time campaign?

A band of 200 armed guerrillas of the little known Free Papua Movement kidnapped 24 people in a remote Indonesian village to protest the regime of President Suharto. The 3,000 strong force of Papuans have been waging a bloody, three-decade campaign to win independence for Irian Jaya province, which covers the western half of New Guinea. The rebels later released 10 of the hostages, and negotiations continued for the remaining captive. Indonesian commandos surrounded the area.
