KALIDASA is one of the greatest poets in the world. He became famous because of his apt similes and imageries in his seven works. He was a playwright and poet. His age is still an unsolved mystery. He is dated between second century BCE and 4th century CE, that means any date in a range of 600 years! Foreigners placed him in Gupta period around 4th century CE. But great Indian scholars dated him around first or second century BCE. I wrote a thesis to get Ph.D.in this matter. But the Sanskrit University asked me to put it in Sanskrit and I am yet to do it. After reading all the 18 books of Sangam Tamil literature and all the seven dramas and poems of Kalidasa, I came to conclusion that Kalidasa lived in Pre-Sangam period. Indian tradition also links him with the greatest of the Indian Emperors, Vikramaditya. After the original Vikramaditya of first century BCE died, hundreds of Hindu Kings called themselves Vikrama or Aditya or Vikramaditya. The proof for my thesis lies in the Kalidasa’s 200++ similes found in Sangam Tamil literature. Sangam poets even used the same epithet to the Himalayas (Kaanchana Srnga- Por Kotu) ‘Golden Peaked’. The first ten slokas of Kumara Sambhava of Kalidasa are used by Sangam poets to describe Himalayas and sages.

The knowledge and general range of interest in Indian history is restricted to Indus Valley Civilization, Mughal Dynasty (that too up to Aurangzeb's reign), Sher Shah Suri (for his building Grand Trunk Road, though it was built long before him), Mohammad-ibn Tughlak (due to the wrong and whimsical actions shown during his reign) and British era (restricted to Battle of Plassey and Lord Clive). Moreover, the major focus of history is oriented mainly around political history. Social and natural history is mostly ignored from general historical information. The 12,000-year-old Indian historical timeline is vast, and it may take years to acquire reasonable knowledge of the history of India. This book makes an effort to catch this vast spectrum of Indian history as a snippet in limited space. Efforts are made to capture social, natural, scientific, art, and human history alongside political history. Indian history, for the general readers, focuses mostly on North Indian (?ry?varta) History. Not many are aware of the rich history of the south of Vindhya Range and also the history of India that exists east of Patna. This book attempts to capture the contemporary history of South India and Eastern India along with North Indian History. The study of history is not complete unless one gets an overall global perspective of a particular period. This book tries to capture contemporary Global History alongside Indian History in that particular age.
