Shantanu was a king of Hastinapura, father of Bhishma. Shantanu weds Satyavati, a ferryman's daughter.
In the epic Mahabharata, Shantanu was a Kuru king of Hastinapura. He was a descendant of the Bharata race, of the lunar dynasty and great-grandfather of the Pandavas and Kauravas. He was the youngest son of King Pratipa of Hastinapura and had been born in the latter's old age. The eldest son Devapi suffered from leprosy and abdicated his inheritance to become a hermit. The middle son Bahlika(or Vahlika) abandoned his paternal kingdom and started living with his maternal uncle in Balkh and inherited the kingdom from him. Shantanu became the king of Hastinapura by default.
