beginning of the 10th century. When Ay power diminished, Venad became the southernmost principality of the Second Chera Kingdom Invasion of Cholas into Venad caused the destruction of Kollam in 1096. However, the Chera capital, Mahodayapuram, fell in the subsequent attack, which compelled the Chera king, Rama varma Kulasekara, to shift his capital to Kollam. Thus, Rama Varma Kulasekara, the last king of Chera dynasty, is probably the founder of the Venad royal house, and the title of Chera kings, Kulasekara, was thenceforth adopted by the rulers of Venad. The end of Second Chera dynasty in the 12th century marks the independence of the Venad. The Venadu King then also was known as Venadu Mooppil Nayar. In the second half of the 12th century, two branches of the Ay Dynasty: Thrippappur and Chirava, merged into the Venad family and established the tradition of designating the ruler of Venad as Chirava Moopan and the heir-apparent as Thrippappur Moopan. While Chrirava Moopan had his residence at Kollam, the Thrippappur Moopan resided at his palace in Thrippappur, north of Thiruvananthapuram, and was vested with the authority over the temples of Venad kingdom, especially the Sri Padmanabhaswamy temple. The Legacy of Venad The most powerful kingdom of Kerala during the era of European influences, Travancore, was developed through the expansion of Venad by Mahahrajah Marthanda Varma, a member of the Thrippappur branch of the Ay Dynasty who ascended to the throne in the early 18th century.

According to the works of Sangam literature, Poozhinadu consisted much of the coastal belt between Mangalore and Kozhikode. Karkanadu consisted of Wayanad-Gudalur hilly region with parts of Kodagu (Coorg). It is said that Nannan, the most renowned ruler of Ezhimala dynasty, took refuge at Wayanad hills in the 5th century CE when he was lost to Cheras, just before his execution in a battle, according to the Sangam works. Ezhimala kingdom was succeeded by Mushika dynasty in the early medieval period, most possibly due to the migration of Tuluva Brahmins from Tulu Nadu. The Mushika-vamsha Mahakavya, written by Athula in the 11th century, throws light on the recorded past of the Mushika Royal Family up until that point.
