With his capital as Mahodayapuram in present day Kodungallur, Kulashekhara Alwar established the second Chera dynasty. Kulashekhara is also credited with writing Perumal Thirumozhi, one of the most celebrated devotional works of the Tamil Bhakti cult.
Rama Varma Kulashekhara was the last Chera King of the second Chera dynasty who ruled from AD 1090 to 1102. He fought a war with his contemporary Chola ruler Kulothunga Choladeva, but the prolonged wars weakened the Chera power. Some Naduvazhis (chiefs) took advantage of this chaotic situation to assert their power.
The Chera kingdom was known for its foreign trade relations; many Arab travellers described the economic boom achieved by the state from its foreign trade. Mahodayapuram fell into the hands of the kingdom of Perumpadappu after the Chera rule.
