History is the science whose object of study is the past of human societies. It's considered to be one of the most important humanistic sciences. It taught human beings to know the cultural heritage of different civilizations, but also to build each one's own identity. By searching and understanding information from the past, it's easier for you to develop your own idiosyncrasies.Yeah homeland past is a great thing to know because it is where you are from and you have felt the present and will want to know why the present is the way it is.
Currently in my country, I noticed a kind a hatred towards my ethnic group by other groups in the country, after looking into the past I noticed that my ethnic group once fought a war for an independent country and lost so it made others see them as stupid and refuse to give us political power so we don't try something stupid.
I would not have known that if I haven't gone through the past archive of my country.
