According to an estimate approximately eight million Indians are living in countries of the world. Although America, France, England, Australia are their favourite countries, and middle-east and south-east Asia are their other favourite regions, the persons of Indian origin are scattered in all parts of the world. They are in several countries of Africa, the Scandinavian countries, Benelux countries, and the Caribbean island countries. In some countries they have mixed with the locals in such a way that at times it is difficult to differentiate them. In some nations, they have been living now for the last 2-3 generations assimilating local culture, language, habits and customs. Most of the Indians who are either working abroad or have permanently settled abroad have kept their roots intact. They are highly patriotic and love India as much as the resident Indians do. A vast majority of the people who have gone abroad from various parts of India have left their parents and other close relatives like brothers, sisters, uncles, aunts, grandparents, etc. at their native place. Such Diasporas have properties and other assets in India and keep on sending money to their parents/ relatives regularly. They have opened various kinds of Non- Resident Accounts in different banks. Many well-off Non-Residents are participating in the private business ventures directly and indirectly. The current boom in India’s share market, to some extent is due to the bulk share purchase of various listed companies by the NRIs. This is indirect participation in Indian industries. Some listed public sector enterprises are also favourite of these investors. It is also said that many NRIs are buying residential and commercial properties in India. This is one of the factors why the prices of real estate have gone up during the last decade or so. The diaspora is particularly interested in buying offices, chambers and shops in multiplexes in metropolitan cities, state capitals, district centres and other major cities in India. This has given a big boost to real estate sector and helped several people connected with housing, construction, furniture and other equipment business. Leaders are either necessary or history is made by them or leaders are merely the expression of popular needs. The first view is called the “leader principle” or the “great-man theory” of history. It holds that people drift along in aimless confusion until a gifted leader assumes command and tells them what to do. He may accomplish social change for good or bad, but the truth is that he appears to accomplish much more than he actually does. For example, Hitler is said to have killed millions of people, but literally speaking, he himself did not kill them and yet he is credited with such events as killing and conquering. The second view is the sociological view.It says that history makes or selects the man, and not vice versa. Social and cultural developments are thought to follow their own laws, and the presence of a particular person as leader is purely coincidental.Few terms in Organization Behaviour inspire less agreement on definition than leadership. As one expert put it, “there are almost as many definitions of leadership as there are present who have attempted to define the concept of leadership.” While almost everyone seems to agree that leadership involves an influence process, differences tend to center around whether leadership must be non-coercive (as opposed to using authority, rewards and punishments to exert influence over followers) and whether it is distinct from management.
