How does political science affect history?

Relation between political science and history:-

the relation between political science and history is very close.It has been put by sir,John Seeley in this couplet.

'History without political science has no fruit'

'Political science without history has no root'

1)History essential for political science:-

History is a record of past events.It provides raw material to political science.political science tells us not only what the state is but also what it has been.The study of the state as it has been can be done only with the help of history.Historical study is essential for understanding political thoughts,movements and institutions history is a vast store house of facts and information as from which political science abtains data for its generalisation.

2)Political science essential for history:-

history has also much to borrow from political science. our knowledge of history is meaningless if the political bearings of events and movements are adequately appreciated.e.g.The history of the nineteenth century Europe cannot be fully understood withoutbringing out the significance of movement like nationalism,Imperialism,individualism and socialism.

3)Difference between the two:-

all this does not mean that history and political science are one and the same.There are fundamental difference between the two. History is a record of past events and movements which embraces wars,revolution,military compaign,economic,political,social and religious upheavals.All this matirial is not required for purposes of political science. The main concern of the student of political science is to study the evolution of political institutions and other facts which bear directly or indirectly on the state.Political science thus selects facts out of history.

Conclusion:-Our conclusion is that political science and history,though they are different subjects yet they touch each other on many points.
