Simuka (Brahmi:π²πΊπ«πΌπ, Si-mu-ka) was an ancient Indian king belonging to the Satavahana dynasty, which ruled the Deccan region. He is mentioned as the first king in a list of royals in a Satavahana inscription at Nanaghat. In the Puranas, the name of the first (Satavahana) king is variously spelt as Shivmukha, Sishuka, Sindhuka, Chhismaka, Shipraka, Srimukha, etc. These are believed to be corrupted spellings of "Simuka", resulting from copying and re-copying of manuscripts.
Based on available evidence, Simuka cannot be dated with certainty. According to one theory, he lived in 3rd century BCE; but he is generally thought to have lived in the 1st century BCE. Epigraphical evidence strongly suggests a 1st-century BCE date for Simuka: Simuka seems to be mentioned as the father the acting king Satakarni in the Naneghat inscription dated to 70-60 BCE, itself considered on palaeographical grounds to be posterior to the Nasik Caves inscription of Kanha (probably Simuka's brother) in Cave 19, dated to 100-70 BCE. Recent analysis of sources puts Simuka's reign possibly around 120 - 96 BCE.
