Santanu

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 latters old age. The eldest son Devapi had leprosy and gave up 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 his kingdom. Shantanu thus became the king of Hastinapura kingdom.Meaning of name shantanu or santanu or śāntanu can be explained by nirukti available in Adi Parva, through which Sri Nityānanda Miśra elaborates its meaning as the one who amplifies sukha (happines) for others. He is best known for being the father of Bhishma, one of the mightiest warriors of all time.
