Mithila After Janaks
It is said that the last King of Janak Dynasty – Kirti Janak was atrocious ruler who lost control over his subjects. He was dethroned by public under leadership of Acharyas (Learned Men). During this period of fall of Mithila empire, the famous republic of Lichavis was rising in Vaishali and Mithila region came under control of Lichavis in around seventh century BC. In 6th century BC, Lichavis were defeated by Ajatshatru of Magadha and thus Mithila region came under control of Magadhan empire. Thereafter several dynasties such as Shaishunag, Nand, Maurya, Shung, Kant, Gupta, Vardhan etc. ruled there from time to time. There was no significant ruler in Mithila after Janaks till 5th-6th century when Jaywardhan Raja Salhesh became King. He made his capital at Mahisautha-Sirha (presently in Nepal). He defended the region against attacks by Tibetans several times. Hence, he was called Shailesh (king of Mountains) from Jaywardhan which in local dialect was called Salhesh.
