Cause:
The Muslim Moplah (or Moplah) peasants of Malabar (Kerala) was suppressed and exploited by the Hindu zamindars (Jenmis) and British government. This was the main cause of this revolt.
Malabar conference:
The Moplah peasants got momentum from the Malabar District Conference, held in April 1920. This conference supported the tenants cause, and demanded legislations for regulating landlord-tenant relations.
Rebellion:
In 1921, the Moplah tenants rebelled against the oppressive zamindars. In the initial phase of the rebellion, the Moplah peasants attacked the police stations, public offices, communications and houses of oppressive landlords and moneylenders.
Impacts:
The government ruthlessly suppressed the Moplah rebellion. As a result of government intervention, 2337 Moplah rebels were killed. 1650 were wounded and more than 45,000 captured as prisoners.
