Explanation: Pabna Agrarian Leagues: During the 1870s and 1880s, large parts of Eastern Bengal witnessed agrarian unrest caused by oppressive practices of the zamindars.

• The zamindars resorted to enhanced rents beyond legal limits and prevented the tenants from acquiring occupancy rights under Act X of 1859.
• To achieve their ends, the zamindars resorted to forcible evictions, seizure of cattle and crops and prolonged, costly litigation in courts where the poor peasant found himself at a disadvantage.
