It is commonplace that the disunity among
the natives inevitably makes a state vulnerable, as it keeps them occupied in
their internal struggles which has the result of drawing their attention from
possible external conquests. A similar event occurred in ancient Sri Lanka, to
be more specific, during the Polonnaruwa
kingdom. Sri Lanka was marked by the Kalinga
Magha invasion in 1215 AD which
led to the fall of the Polonnaruwa
kingdom along with several other factors which were equally undesirable to
the continuity of the kingdom. However, the other reasons aside, the Magha invasion alone can be looked on
as a climax point of Sri Lankan history due to two reasons. Firstly, it
operated as the immediate cause among a number of long term causes for the
collapse of the Polonnaruwa kingdom.
Secondly it marked a striking change of the capital of Sri Lanka which was
transferred from Polonnaruwa to Dambadeniya.
