I want to know the answer to the following question:
What Muslim endeavors thrived on the coastal areas of south India?
All the background I'm provided with is that "Mahmud of Ghazni in the early 11th century raided mainly the north-western parts of the Indian sub-continent 17 times, but he did not seek to establish "permanent dominion" in those areas.". Is that enough to answer the question?
Answer: no
