glimpses of life in the city. He describes Kozhikode as "one of the great ports of the district of Malabar" where "merchants of all parts of the world are found". The king of this place, he says, "shaves his chin just as the Haidari Fakeers of Rome do... The greater part of the Muslim merchants of this place are so wealthy that one of them can purchase the whole freightage of such vessels put here and fit-out others like them". Ma Huan (1403 AD), the Chinese sailor part of the Imperial Chinese fleet under Cheng Ho (Zheng He) states the city as a great emporium of trade frequented by merchants from around the world. He makes note of the 20 or 30 mosques built to cater to the religious needs of the Muslims, the unique system of calculation by the merchants using their fingers and toes (followed to this day), and the matrilineal system of succession.

As the Vijayanagara power diminished over the next fifty years, the Zamorin of Kozhikode again rose to prominence in Kerala. He built a fort at Ponnani in 1498. The Kingdom of Venad Venad was a kingdom in the south west tip of Kerala, which acted as a buffer between Cheras and Pandyas. Until the end of the 11th century, it was a small principality in the Ay Kingdom. The Ays were the earliest ruling dynasty in southern Kerala, who, at their zenith, ruled over a region from Nagercoil in the south to Thiruvananthapuram in the north. Their capital was at Kollam. A series of attacks by the Pandyas between the 7th and 8th centuries caused the decline of Ays although the dynasty remained powerful until the
