Vikramaditya (IAST: Vikramāditya) was a legendary king[1][2][3] as mentioned in ancient Indian literature, featuring in traditional stories including those in Vetala Panchavimshati and Singhasan Battisi. Many describe him as ruler with his capital at Ujjain (Pataliputra or Pratishthana in a few stories). "Vikramaditya" was also a common title adopted by several monarchs in ancient and medieval India, and the Vikramaditya legends may be embellished accounts of different kings (particularly Chandragupta II). According to popular tradition, Vikramaditya began the Vikrama Samvat era in 57 BCE after defeating the Shakas, and those who believe that he is based on a historical figure place him around the first century BCE. However, this era is identified as "Vikrama Samvat" after the ninth century CE.
