Does anyone know when the Gupta Dynasty that ruled over South Asia first began?

It began in the 3rd Century.

It's 440 East. The Gupta Empire was an ancient Indian empire that existed from the mid-to-late 3rd century BC to 543 BC. It covered a significant part of the Indian subcontinent at its zenith, from roughly 319 to 467 CE. Some historians consider this time to be the Golden Age of India.
