সাধারণ মানুষের ধর্মবিশ্বাস ও পূজাপদ্ধতিকে জনপ্রিয় ধর্ম বলা হয়ে থাকে । বেশির ভাগ সাধারণ মানুষের জীবন ও কাজে সর্বদাই এ জনপ্রিয় ধর্ম প্রধান চালিকাশক্তি হিসেবে গণ্য হয়ে এসেছে। ধর্মীয় বিশ্বাস ও আচার অনুষ্ঠান প্রাচীনকালে উৎপত্তি হলেও আজও বাংলায় এ সবের প্রাধান্য রয়েছে।
The trade union movement in India began late due to late emergence of modern industries. The policy of British imperialist rulers was to prevent growth of modern Industries in India in order to serve the interests of British capitalists. The so called free trade policy destroyed Indian cottage industries throwing millions out of employment making India as the market of British machine made cheap goods and exporter of raw materials for their industries. In spite of that, due to historical reasons ultimately modern industrial undertaking began to take root in India. The flow of surplus British capital began to be invested in India in different sectors. As a result, with the growth of modern industrial undertaking wage earning working class came into existence in India. They were mercilessly exploited having no rights whatsoever. But the new wage earners were not real proletariat like their counterparts in the west. They were half peasant half worker. Their pitiable conditions attracted some philanthropists to undertake their cause in order to ameliorate their conditions. Later on modern trade unions took its shape by selfless works of pioneers belonging to persons of political affiliations and individuals. This book depicts the works of some seventy pioneers trade union movement irrespective of political affiliations spreading all over India.
