Resort to extremism by some sections of an ethnic group usually triggers inter-ethnic conflicts with other groups on the one hand and leads to confrontation with the state on the other. This paper seeks to examine the dynamics of this phenomenon in the context of Bodos, the largest plains tribe of Assam, a State of Northeast India. The paper enquires as to whether extremist politics has met the Bodo aspirations for self-determination or has intensified the conflicts and contradictions within the Bodo society with ramifications for other ethnic groups inhabiting the Bodo-dominated areas. It is also necessary to explore the responses of the Union and State governments to Bodo extremist politics for an understanding of the conflict management process.展开更多

文摘Ethnic assertions worldwide have assumed different forms ranging from moderate methods of articulation of autonomy to extremist means of violent struggle. Resort to extremism by some sections of an ethnic group usually triggers inter-ethnic conflicts with other groups on the one hand and leads to confrontation with the state on the other. This paper seeks to examine the dynamics of this phenomenon in the context of Bodos, the largest plains tribe of Assam, a State of Northeast India. The paper enquires as to whether extremist politics has met the Bodo aspirations for self-determination or has intensified the conflicts and contradictions within the Bodo society with ramifications for other ethnic groups inhabiting the Bodo-dominated areas. It is also necessary to explore the responses of the Union and State governments to Bodo extremist politics for an understanding of the conflict management process.
