I want to know the answer to the following question:
From where did the Arab traders come in order to trade on the west coast of 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?
