The question of nationalism has been debated widely by scholars especially in the 20th century. Some of the questions that were under scrutiny concerned the definition of the terms nationalism and nation and also on the probable time frames within which nations first appeared.
Among the widely accepted theories asserts that nations have been there for a long time and that they take different shapes as time progresses. There are those that argue that the nation phenomenon is timeless and that mankind has been in the process of developing nations since his appearance in the universe.
Whether nations occurred naturally or were constructed by man’s efforts as some have suggested, there seems to be a unique attitude among members of a nation that causes them to show pride or care on their nationhood (Calvert & Calvert, 2007). There have also been determined efforts by members of a nation to seek self determination in the past which implies that there is a force that evidently joins people belonging to one nation together. This force or forces are the causes that are assumed to cause nationalism.
