Gentlemen, I just goggled history of Magar and found lots of things. if there was no history of Magras how come all those things appear in Google? there are books the basic book is "Mechi dekhi Mahakali" it gives some basic idea about different tribes of nepal. and there is also a book written by Yogi Naraharinath. Anyway just by Goggling you will come to know so many things about "Magars" and so is about other cast. So please do research before writing something, it helps The information about different ethnicity may not be available in depth. General information is good enough for ordinary people who want to know in general. If you want to know in depth about different ethnic groups of Nepal (I think there are about 100 different ethnic groups in Nepal) and if there is no books available the best thing I believe is to select that field for you future study, one can do PhD in any ethnic group and if you are already done with study you can finance the study or start PhD programme on it or announce some monitory award whomever write the book about the ethnicity of your concern. Please don’t dictate that the kids in school need to study in depth history. They just need to learn general history; mostly they need to learn is science, mathematics and management so that they can compete with the world. And for those who are not interested in those fields they can choose history (or any other subject) and I believe it must be world history with reference to the ethnic groups. but this have limited job market. If you are a middle age person and have kids and if you are so much interested in ethnic history you may try to pursue your kids to study history, if he/she agrees. History is important; it tells how our forefathers lived. But it is not important than your survival at present. If you don’t know the history of some ethnic group you can survive but if you don’t have basic qualification to survive the present, history won’t save you. And, if you believe in science we all evolved from amoeba (single celled organism) then some sort of monkey (may be one or different species, I don’t remember) we know the history of monkey and amoeba don’t we. If you believe in god, its all because of god we don’t need to worry. For me personally I may be interested in history when I am old I don’t know yet, at present I am competing with different ppl in the field of science I need to know more of modern things rather than history. I don’t want to live by knowing what happened in the past rather I want to live by knowing how I can manage the future. It is getting too lengthy I better stop here. Thanks
