Panoramic view of graded structures from Euler and Bourbaki–Krasner to Krasner–Vuković

The paper begins with a note about A. V. Mikhalev and a short introduction to some historic facts about graded structures that are old as well new by M. Krasner. Later, we give a panoramic view of more general Krasner graded groups and introduce Krasner–Vuković's paragraded groups and conclude with some results in the theory of paragraded groups.
