The economy is inextricably linked with our daily lives. In Ancient India also there was no exception. This economic trend has changed at different times. Like the reshuffle of power, the change in the course of economy was also noticeable. The wheel of the economy was sometimes upward and sometimes downward. Sometimes the wheel of the economy was the cause of power shifting. Because the economically powerful rulers wanted to seize power by invading his neighboring states. That's why the rulers wanted to run the economy of his state smoothly. One of the policy makers of the Ancient India like Maurya, Gupta, or whatever the period was depended on how active the economy of that period was. This book has been written on the basis of reviewing some related literature, articles written on the basis of Ancient India. Although there are many primary sources written on Ancient India, but those sources do not deciphered, so for this research I have to rely more on the secondary sources.Data has been collected from all these sources and after verified those I used them in my present research. Due to the scarcity of information on Ancient India, some limitations had to be met in completing the research. Secondary sources of data have been used in this research which collected from various types of articles, books, thesis paper and so on. All kind of secondary sources have been considered as data collection tools based on economic system of Ancient India. Special attention should be given for making this research more effective, successful and target oriented. First of all collected data has been processed, analyzed and interpreted for research findings.
