The characters in Bengali historical novels are often complex and reflect the values and attitudes of the time. They could be freedom fighters, social reformers, or ordinary people trying to make a living in a changing society. The language used in these novels also adds to their charm, as it might use archaic Bengali words or expressions that were common in the historical period being depicted, which gives readers a sense of authenticity and a connection to the past.
They often depict historical events. For example, novels might show the various uprisings against colonial rule in Bengal. This gives the readers a sense of the past struggles.
Religious and cultural traditions are also major themes. Bengali historical fiction often showcases the influence of Hinduism, Islam and other religions on the society. It also shows how cultural practices like festivals, marriage ceremonies etc. have evolved over time and how they were different in the past. For example, descriptions of Durga Puja in different historical periods can be found in many works.
Another great historical Bengali novel is 'Rajmohan's Wife' which was the first Bengali novel to be published. It gives insights into the social and cultural aspects of that era in Bengal.
One well - known Bengali historical novel is 'Anandamath' by Bankim Chandra Chattopadhyay. It is set against the backdrop of the Sannyasi Rebellion and is also known for the song 'Vande Mataram' which was inspired by it.
Since I don't know the specific 'first Bengali detective story', it's hard to say exactly. But generally, it might have a local setting, perhaps in Bengal, with characters that are relatable to the Bengali audience.
