Introduction to Ramasimhadeva

King Ramasimhadeva was a powerful king who ruled the Tirhut Kingdom for 45 years, from 1227 A.D. to 1272 A.D. He was the son of King Narasimhadeva and took over the state administration of Simraungadh after the reign of his father Narasimhadeva.

He is known for his military conquests. In fact, he conducted simultaneous attacks on the Kathmandu Valley. The First One took place in 1242 A.D. whereas the second one took place in 1243 A.D.

Life and Reign of King Ramasimhadeva


King Ramasimhadeva was born in 1183 A.D. as the son of Narasimhadeva in the Tirhut Kingdom. He became the King of Tirhut Kingdom at the age of 44 Years and ruled for 45 Years.

At the beginning of his reign in 1242 A.D., he gathered a large army and decided to attack Nepal. Abhay Malla was ruling Nepal at the time. It is said that many disasters were occurring during these times.

Military Attacks On Nepal

King Ramasimhadeva was an ambitious King who wanted to conquer and rule Nepal as a whole. Following the footsteps of his great-grandfather King Nanyadeva, he gathered a large army and traveled North toward Nepal in 1244 A.D.

In the Gopal Raja Bansawali, it has been mentioned that King Ramasimhadeva had traveled together with his army when they were stopped on a hill by the forces of Kathmandu. A vicious war ensued and the Tirhut King lost for the first time.

King Ramasimhadeva attacked Kathmandu for the second time a year after 1245 A.D. In this instance, he arrived fully prepared to attack and defeat Nepal. After his Arrival in Nepal, another fight ensued in the Jungle of Gokarna.

Both armies seemed equally powerful but The Malla Army got the upper hand and surrounded the Army of Tirhut Kingdom.

After being surrounded, most of the armies were viciously slaughtered and only a few remained. The Armies started to run away including King Ramasimhadeva.

Consequently, King Ramasimhadeva was defeated even for the second raid on Kathmandu. Following the loss of King Ramasimhadeva, the Tirhut Kingdom didn’t attack Nepal for 50 More Years.

Contributions of King Ramsimhadeva

Although King Ramasimhadeva failed to defeat Kathmandu Valley twice, he certainly brought some changes in his long reign as the King of the Tirhut Kingdom. He brought land reforms, developed the economic and cultural aspects of the Tirhut Kingdom, and protected the Tirhut Kingdom from External Invasions.

Administration and Literature

He was a patron of the arts, literature, and philosophy. He was provided the Titles “Mithila Mahendra” and “Mithiladhipati”. Ramasimhadeva has been attributed to have ruled the Tirhut Kingdom for 92 Years according to ancient Mithila documents which seems quite false.

Protection of Tirhut

Ramasimhadeva saved the state of Simraungadh by strengthening the relationship with the Muslim powers when the Pal and Ron powers were beginning to disappear due to the Turkish Muslim attack at that time.


King Ramasimhadeva is much known in the Mainstream History of Nepal because he conducted several raids to defeat the Kathmandu Valley and followed the footsteps of Nanyadeva.
