The document discusses the introduction and expansion of indigo cultivation in Bengal in the late 18th and early 19th centuries by the British East India Company. It notes that indigo plantations grew rapidly in Bengal to meet the rising demand for indigo in Europe. The Company and colonial officials invested in indigo production and many took up indigo cultivation as planters. There were two main systems - nij cultivation where planters directly controlled land and ryoti cultivation where peasants were forced through debt to cultivate a portion of their land with indigo. Peasants found the ryoti system harsh as loan cycles never ended and prices received for indigo were very low.
