There are some objective factors whose presence has been helpful in evolving the nation. It is at the same time asserted that the presence of each or any of them is not absolutely indispensable. The more important of such factors are: the community of language, geographical and common economic ties and common history and traditions. But there is no unanimity even in respect of them. According to Professor Maclver there are scarcely any two nations which find their positive support in the same objective factors.
I. Race and Kinship: While it is true that unity of race and kinship helps in cementing people together, to argue that such unity is an indispensable objective factor is unacceptable.F.Schuman points out if pure races ever existed they have long since disappeared as a result of migrations, wars, conquests, travels over thousands of years. All modern nations have been formed out of peoples of diverse racial and tribal groups.
II Community of religion: Unity of religion has been and can be a great cementing force and has played a significant role in the past in consolidating nations. The modern nation is a territorial community. It includes and embraces all persons of ethnic stock and religious faith residing on a permanent basis on the same territory and therefore also participants in the history and traditions of the land. In this age of democracy and secularism to advance religion as an objective factor indispensable for the formation of a nation is to encourage religious bigotry and persecution and thereby to undermine the very foundations of secular democracy.
III Common history or traditions: The possession of a common language, geographical contiguity and common economic ties are bonds which make the people living together share same experiences and develop a certain amount of common outlook and also have common aspirations. This creates among them a common psychological make-up or character. The character of people is a reflection of the conditions of life they have lived and led together. The reference to national character does not negate the existence of individual variations.
IV Community of economic ties: This point was emphasized by Karl Marx. Since then its significance has been realized. When it was conceded that the nation was a historical and a sociological phenomenon, attention began to be paid to the conditions under which nations arise. A nation as a territorial community could not exist in the ancient period or in the ages of slavery and feudalism. The nation arises out of the fusion of clans, tribes and ethnic groups. It is the growth of exchange between regions and the creation of a home market which leads to the creation of nationalities.
Nationality is a psychological disposition or sentiment. According to Zimmern nationality like religion is subjective psychological, a condition of mind, a spiritual possession, a way of feeling, thinking and living. Nationality is an instinct. It is a cultural concept. It springs from a heritage of memories whether of great achievement and glory of disaster and suffering.Maclver defined nationality as a type of community sentiment created by historical circumstances and supported by common psychological factors to such an extent and so strong that those who feel it desire to have a common government peculiarly or exclusively their own.
