Step 1: Understanding the Concept
The query requires clarification of the term 'dikus' within a historical framework, specifically referencing tribal rebellions in colonial India.
Step 2: Detailed Explanation
The term 'diku' was commonly employed by tribal populations of the Chotanagpur plateau, such as the Mundas and Santhals, to designate outsiders. These individuals were viewed as exploitative forces that disrupted established tribal societal norms.
The term specifically encompassed:
- Moneylenders and traders: These individuals entered tribal regions, ensnared tribals in debt cycles, and appropriated their landholdings.
- Zamindars (landlords) and contractors: Granted land by the British administration, they exploited tribal labor.
In essence, 'dikus' were non-tribal individuals who entered tribal territories with economic objectives and were perceived as instrumental in the tribals' suffering. Consequently, 'Migrant traders and Money lenders' offers the most precise definition.
Step 3: Final Answer
Tribals utilized the term 'dikus' to identify outsiders, predominantly exploitative migrant traders and moneylenders. Therefore, option (3) is identified as the correct response.
