Page "Kodungallur" Paragraph 5

The glory of Kodungallur, as a global trade centre, is believed to be destroyed by natural calamities.

According to one view it was heavy floods in the river Periyar that destroyed the city in 1341, while others point out to an earth quake in this regard.

The floods further split the left branch of the river into two, just before the city of Aluva.

The flood silted the right branch ( known as River Changala ) and the natural harbour at the mouth of the river to make it poorly navigable for large ships.

The misfortune of Kodungallur helped other major ports of Malabar coast, such as the one at Kochi, to rose to the prominence.
