The Ikshavaku dynasty is one of the imperial dynasties which ruled over Earth and were the desecndants of Surya Dev, the originator of energy and light to the whole world.
Shri Ram was the 62nd king who ruled over the Ikshvaku dynasty along with his four brothers whose story is forever embedded in the most illustrated epic of Ramayan, authored by Rishi Valmiki. In this epic, Maharshi Valmiki not only wrote the entire story of Shri Ram along with his brothers and the royal family, but also in detail mentions the ancient places which were bequeathed by Shri Ram to his descendants rule over after his time. These places are still present and popular for the history they carry and are noted as the prominent cities in today‘s times.
Shri Ram’s and his brothers Bharat, Lakshman and Shatrughan all had twin sons. These sons were as just, righteous and great warriors as their fathers and ruled over great cities which were first founded by Shri Ram and his brothers and later on continued to be ruled by their sons.
Luv and Kush were the sons of Shri Ram. Tutelaged under Rishi Valmiki, Luv and Kush were worthy successors of Shri Ram. After Mata Sita left for the heavenly abode through Mother Earth, Shri Ram continued his rule as the king of Ayodhya in adherence to Dharma. After fulfilling his purpose of incarnation of retaining the Dharma, Shri Ram decided to end his incarnation. He then entrusted the kingdom to his two sons.
Kush, the elder one was crowned as the king of Kushavathi (also called as Kasur in today’s times) presently a prominent place near the Vindhya Ranges. Luv was installed as king to Lavpuri, which is recognised as present day Lahore, and both were a part of the Kosala kingdom.
Bharat was the founder of the famed Takshashila city, which flourished near the Indus River and was famous for having one of the first Universities of India. Bharat’s sons Taksh and Pushkal ruled this kingdom, Taksh ruling Takshashila, on his name and Pushkal ruled the kingdom Pushkalavathi, the Gandhara kingdom of the Mahabharat times.
Shri Ram ordered Lakshman to spread the kingdom in other areas too, and thus, Lakshman was the founder of the kingdom of Lakshmanapur, which is noted as the present day Lucknow. Lakshman was entrusted to help his sons Angad and Chitraketu establish their kingdom and Lakshman stayed there for a year till his sons were capable of handling the kingdoms. This is the only time that Lakshman stayed apart from Shri Ram in his whole life. Angad ruled the kingdom of Karupada in Odisha region and Chitraketu owned by Malwa region and both were great rulers under which the kingdoms prospered.
By killing Lavanasur, Shatrughan was already the ruler of Mathura as a righteous ruler and got as much as love as Shri Ram from his subjects, for his worthy rule. Mathura flourished as one of the great kingdoms and this was where Shri Krishna was born again in the Dwapar Yug. One of his twin son Subahu ruled over Mathura and the other Shatrughati was appointed as the king of Vidisha, the neighbouring region.
Thus, Shri Ram saw to that all of his descendants got their right to rule as per their noble characteristics and continued to follow Dharma just as Shri Ram and his brothers, as their perfect successors.
