Taking full advantage of King Yasalalakatissa’s jest, Subha, who was a gatekeeper, killed the king and ascended the throne. Very little information about him is available in the main historical sources. However, certain terms used in these texts help us to understand who he was.
In the Mahavamsa, Subha is described with two words — Dovārika and Balattha. The first term, Dovārika, literally means “gatekeeper,” but it does not necessarily refer to a mere guard. In ancient Anuradhapura, this was a powerful position, similar to that of a Vahalkada Nilame in later times — a royal official with high authority. The second term, Balattha, means “one associated with power” or “a man of influence.”
In fact, when King Dutugemunu was building the Ruwanweliseya, it was a Balattha who was assigned the task of identifying the monk who had secretly laid the first brick. Therefore, the title referred to a trusted royal officer. It seems that Subha, too, had been a close and trusted subordinate of King Yasalalakatissa, and when the opportunity arose, he used it to his advantage.
The only mention of Subha’s ancestry in the Mahavamsa states that he was the son of Daththa the gatekeeper (Dovārika Daththa). Nothing further is known about Daththa from literary sources. However, inscriptions provide valuable evidence.
Several rock inscriptions discovered at Kaduruwewa Vihara in the North Western Province mention a person named Datha (or Daththa), who served under a king named Mahanaka as Amathi (minister) and Mahadovārika (chief gatekeeper). Scholars believe that this King Mahanaka could be either King Mahadatika Mahanaga or King Ilanaga, though that is not crucial here.
From these inscriptions, it becomes clear that Daththa’s family held high-ranking royal offices for at least four generations, indicating a powerful and well-established lineage. The earliest known ancestor, Vahiti, was a chief minister. His son, Tissa, was a nobleman (Radala). His son, Vahitimada, was again a minister, and his son Tissa held the titles of Kanapedi (record keeper) and Amathi (minister). The next in line was Datha (Daththa) himself. The genealogy after Daththa is not recorded.
From these records, it is evident that Daththa’s family was both influential and wealthy. The inscriptions mentioning his donation of tanks and lands also show that he was a man of great wealth. Moreover, the name Vahiti, found at the beginning of the lineage, suggests Brahmin origins. It is well known that many Brahmins in ancient Lanka held high government positions.
Based on the script style of the Kaduruwewa inscriptions, scholars conclude that Daththa the gatekeeper mentioned in the Mahavamsa is likely the same Datha mentioned in these inscriptions, and that Subha was his son. Thus, Subha would have been of Brahmin descent.
Historical and inscriptional evidence indicates that Brahmins had been settled in Sri Lanka long before the arrival of Buddhism. After the introduction of Buddhism, many of them became lay followers (Upāsakas) of the Buddha. However, some Brahmins may not have been supportive of the spread of Buddhism. Historical records show that certain Brahmins even attempted to seize political power in Sri Lanka — as seen in the Brahmana Tissa Rebellion during the reign of King Valagamba.
In this light, it is not implausible to think that Subha, too, may have taken advantage of a situation to kill King Yasalalakatissa and attempted to establish a Brahmin royal dynasty in Lanka.
The Mahavamsa also records that King Subha constructed several monasteries. Among them was the Subharama — a beautiful monastic complex at the Mahavihara — said to have been built by him. He also founded the Valli Vihara near Urulewella. Archaeological and inscriptional evidence suggests that the site known today as Valiwehera in the Ponparippu area of the present Puttalam District corresponds to this Valli Vihara. These inscriptions confirm that Subha’s royal authority was recognized in those regions.
Another monastery attributed to him was the Ekadvarika Vihara (Monastery of the Single Gateway). Inscriptions refer to two such monasteries. One is believed to have been located near the village of Galenbindunuwewa in the North Central Province, known today as Veheragala. An inscription found there records that King Saba (Subha) constructed an Uposathaghara (ordination hall) in the Ekadvarika Monastery and donated a pond named Upaladoni for the use of the monks. Another inscription from Kainattama mentions that the king also offered a reservoir to the monks.
From these inscriptions, historians have confirmed that the “Saba Raja” mentioned is indeed King Subha of the Mahavamsa. The fact that inscriptions corroborate the chronicle’s account greatly enhances the credibility of the Mahavamsa.
Another monastery built by the king was the Nandigama Vihara, located near a river, though its exact site remains unidentified. The Mahavamsa Tika (commentary) mentions that it was situated near the Kacchaka River, which is thought to be a tributary of the Mahaweli Ganga.
The chronicles also state that King Subha had a daughter. Because astrologers predicted that her son would one day become a great ruler, the king placed her in the care of a mason (referred to as Itthakavaddhaki or Uluvaddu for protection). Her name was Mahametta (or Mahamatta). A rock inscription at Wilewewa confirms details concerning this princess.
Although not mentioned in the chronicles, inscriptions reveal that King Subha also had a son named Tissa Maharaja. A rock inscription at Muwangala in the Ampara District records an offering made to the Muwangala Vihara by this prince, identified as the son of King Subha. It seems that after Subha’s death, Tissa temporarily ruled as the Maharaja of Ruhuna, though not for long.
King Subha’s reign lasted six years, and inscriptions indicate that his authority was recognized throughout the island.
As we have seen, if King Subha indeed tried to establish a Brahmin royal lineage, it was short-lived. His successors soon disappeared from history. Nevertheless, King Subha remains remembered as the man who ended the first Mauryan line of rulers in Sri Lanka — a dynasty that began with King Pandukabhaya and ended with the assassination of King Yasalalakatissa.
