The period between the 4th century and 6th century CE is known as the Golden Age of india because of the large achievements Indians made in the fields of mathematics, astronomy, science, religion and philosophy during the Gupta Empire. The decimal numeral system, including the concept of zero, was invented in India during this period. The peace and prosperity created under leadership of Guptas made remarkable scientific and artistic activities in India possible. The Golden Age in India came to an end when the Hunas invaded the Gupta Empire in the 6th century CE.
