List of Sri Lankan Monarchs - Note On Chronology

Note On Chronology

It should be borne in mind that there is controversy about the base date of the Buddhist Era, with 543 BC and 483 BC being advanced as the date of the parinibbana of the Buddha. As Wilhelm Geiger pointed out, the Dipawamsa and Mahawamsa are the primary sources for ancient South Asian chronology; they date the consecration (abhisheka) of Asoka to 218 years after the parinibbana. Chandragupta Maurya ascended the throne 56 years prior to this, or 162 years after the parinibbana. The approximate date of Chandragupta's ascension is known to be within two years of 321 BC (from Megasthenes). Hence the approximate date of the parinibbana is between 485 and 481 BC - which accords well with the Mahayana dating of 483 BC.

According to Geiger, the difference between the two reckonings seems to have occurred at sometime between the reigns of Udaya III (946–954 or 1007–1015) and Pârakkama Pandya (c. 1046–1048), when there was considerable unrest in the country. However, mention is made of an embassy sent to China by Cha-cha Mo-ho-nan in 428. The name may correspond to 'Raja (King) Mahanama', who (by the traditional chronology) reigned about this time.

Furthermore, the traveller-monk Xuanzang, who attempted to visit Sri Lanka about 642, was told by Sri Lankan monks (possibly at Kanchipuram that there was trouble in the kingdom, so he desisted; this accords with the period of struggle for the throne between Aggabodhi III Sirisanghabo, Jettha Tissa III and Dathopa Tissa I Hatthadpath in 632–643.

Recent indological research has indicated that the Parinibbana of the Buddha may be even later than previously supposed. A majority of the scholars at a symposium held in 1988 in Göttingen regarding the problem were inclined towards a date of 440–360 BCE. However, their calculations were based on the chronology of Tibetan Buddhism, preferred over that of the Dipavamsa/Mahavamasa; the modified chronology, in order to work, needs to identify the Indian ruler Kalasoka, son of Susunaga, with the Emperor Asoka, son of Bindusara. It should be noted that the Sri Lankan chronicles are based on even earlier works and that the Buddhist canon was first put into writing in Sri Lanka. The chronology of the following list is based on the traditional Therevada/Sri Lankan system which is based on 543 BC, or 60 years earlier than the Mahayana calendar. The dates after c. 1048 are synchronous.
