user12011: I want to know if Buddhism was practised in Kerala, India around 500CE. When did it lose popularity and why?

user12013: No it was not practiced. In Kerala very minor group of people follow the Buddhism. Buddhism probably flourished for 200 years (650-850) in Kerala. The Paliyam Copper Plate of the Ay King, Varaguna (885-925 AD) shows that the Buddhists benefited from royal patronage in the 10th century.
Hope this helps..
