Following four are ibn-e-khaldun's major contributions:

1) Methodology for writing, studying and understanding history
2) Theory of social solidarity i-e al-asabiya
3) classification of society in rural and urban
4) cyclic theory of social change-thus pioneering what came to be known as "conflict perspective" later.
