Students were very active and struggling against the king Mahendra’s bad temptation towards democracy in 2017 B.S. As a result, there was a necessity of a group of youths who could support the principle of Nepali congress. Considering the philosophy of Nationality, democracy, socialism and student unity, the whole youths of student of country were included under the umbrella of student union  which was called Nepal students Union.

Ideologies:

Nationality: B.P Koirala has said, “Country and Nation is not that geography or territory rather nationality is the word which targets to the spirit of collective people”. Nationality is a feeling which is emerged spontaneously to let out the any kind of crisis. There are three significant factors under that definition.
a) Universality b) The trial to solve it and c) the unification of emotion emerged through the trial.
Nepal Student Union has always been to save the sovereignty and self-existence of people. To solve the critical problems of country, to have saved the essence of Nepali, to protect the self-pride of being Nepali and to develop the feelings of “I am Nepali”. NSU has regarded the nationality, which cannot be strengthened without democracy.
