King Mahanaga
Kingdom of Anuradhapura
573 AC - 575 AC

After King Kittisirimegha, the throne was ascended by a royal scion named Mahanaga. He became the founder of a new royal lineage. A remarkable episode concerning this king is described in the Mahavamsa. According to the Rajavaliya, he was a Maurya descendant and a Senavi. The Mahavamsa describes the story as follows:

During the reign of King Silakala, a Maurya descendant named Bhayaseeva lived in the village of Dvasa Sangilla. He had a son named Agbo. Bhayaseeva’s sister also had a son named Mahanaga. Mahanaga, abandoning farming, became a forest-dweller and lived in the wild. At one point, a villager brought some rice to Bhayaseeva’s wife, and she sent a portion to him. Then Mahanaga captured a slave and sent him to a miller, who also sent some rice. Later, Mahanaga sent a message requesting rice from his cousin, and in return, he received a servant along with the rice.

Through these events, Mahanaga grew in strength at a time when the country was suffering a famine. A Brahmin, who was also suffering due to lack of food, befriended Mahanaga by providing him with sustenance. Pleased by this, Mahanaga resolved that he should ascend the throne. From the riverbank at Gokarna, a naga (serpent magician) was summoned to assist him. Initially, Mahanaga failed to heed the naga’s directions during the first and second attempts, but on the third, he touched the naga with three fingers. The naga then told him that he would fight against three kings, kill the fourth, ascend the throne, and rule for three years. He also instructed that three members of his lineage would also ascend the throne, and he should guide them to serve in the city.

Following this event, Mahanaga went to Anuradhapura and served the king as an official. This occurred during King Silakala’s reign. The king appointed him as the revenue officer of Ruhuna. Acting to please the king, Mahanaga was given the honorary title of commander and was allowed to settle in Ruhuna. This was a strategic move to bind a potentially dangerous person through alliance. Consequently, Mahanaga effectively controlled Ruhuna during Silakala’s reign.

He strengthened his position while Agbo and Banna were taken to Ruhuna, where they created unrest. This happened toward the end of King Silakala’s reign. Thus, Mahanaga gained full control over Ruhuna and then focused on subjugating Malaya, which was then ruled by Prince Dathapabhuti. Perhaps his initial aim was to consolidate Malaya before taking Anuradhapura. However, Mahanaga’s plans were thwarted because he had to retreat in the face of the Moggalana prince, who came to confront him in the east.

After Silakala, Dathapabhuti ascended the throne by force, as previously noted. Legally, the rightful heir, a senior prince, fought Dathapabhuti and was killed, after which the Moggalana prince donned the royal robes. Mahanaga had to remain passive in the presence of the Moggalana prince. Although he attempted to benefit from the conflict between Dathapabhuti and Moggalana, the battle ended quickly, and his efforts were in vain.

Moggalana himself had not yet established firm control over Anuradhapura, so Mahanaga was not in a position to fully oppose him. Mahanaga ruled Ruhuna, and Moggalana did not challenge him thereafter. Though the naga magician had prophesied that he would fight three kings, Mahanaga only fought Dathapabhuti. By instigating unrest in Ruhuna against King Silakala, taking control of the region, and then returning after attempting to attack Prince Dathapabhuti in Malaya, and by killing the infant prince Kittisirimegha to claim the throne, the naga’s prophecy could be considered fulfilled. Historically, however, the magician’s account is not significant. Such tales often circulate about rising rulers, sometimes granting mystical legitimacy to princes without rightful claims.

Mahanaga is described in the Poojawaliya and the Rajavaliya as a Senavi king of Maurya descent.

He spent a long period, reportedly fifty-eight years, quietly preparing the background necessary to achieve his goals. During Kittisirimegha’s reign, the administrative disruption caused by his mother’s interference created instability in the kingdom. Mahanaga, with his army, came from Ruhuna and initially seized power by killing the king and taking control of the throne. This marked a reestablishment of the Maurya lineage, which had been dormant for some time, as noted by Professor Senarat Paranavitana. Nevertheless, the independent region of Ruhuna, after his intervention, was integrated again into Anuradhapura, and peace was restored in the kingdom.

Mahanaga became king at an advanced age. Even so, he faced significant challenges. After ascending the throne, he summoned his cousin Agbo to Ruhuna, as the previous king had died. Agbo, the son of Bhayaseeva, was appointed as crown prince. His mother’s name is not mentioned in primary sources, but he is known as Agbo. The king sent a message for him to come to Anuradhapura, but Agbo encountered obstacles on the way, returned, and died after a few days. Agbo, therefore, was the prince who went to Ruhuna.

After establishing proper governance, Agbo worked to restore the Dhamma, following the example of previous kings. He first repaired the Mahabodhi shrine, renovated the Ratnaghara, and installed a Buddhist image. He oversaw the construction of the Mahasaya, the Vajrachubba, and built walls and paintings. Several villages were dedicated to the Mahavihara and Jetavana. Three hundred cetas were dedicated to Jetavana, and ten thousand to the Mahavihara. Establishing a charitable dana chatta (donation post) was a notable act of his reign. Numerous regional temples were renovated, and the Mahavamsa records that he performed many additional pious works.

During Mahanaga’s reign, the country’s economic development also improved. It appears he accomplished much within a relatively short period. Consequently, peace prevailed throughout the land. His authority was recognized as far south as the farthest regions and in the north as well. According to the naga’s prophecy, Mahanaga ruled for three years in the presence of the Moggalana prince. He became the founder of the third Maurya-descended royal line. Professor Paranavitana notes that this period marked an unstable era in the succession of kings.
