Dear Aspirants,

India is one of the few countries in the World to have a great cultural past. We can trace the elements of our culture to more than 5,000 years. The uniqueness of Indian culture is that it absorbed all the elements of foreign culture which tried to interfere in India in the past and yet maintained its originality without much change.

We are what we are today due to our cultural past. So understanding ourself would be incomplete without studying our cultural past. It is because of this that the UPSC has made culture as a integral part in its syllabus. In the recent years more questions are being asked in this area in both Preliminary and mains exams.

Preparing the culture topic is a bit difficult, because of lack of comprehensive and holistic material. We try to simplify your preparation by giving this material. This material covers all the topics needed for UPSC, which has been supplemented with appropriate figures and photos. This material will help your UPSC preparation in a great way.

We wish you all the best for your success in UPSC & happiness in life.
