Kollam Azhintha Andu

Kollam Azhintha Andu (Tamil: கொல்லம் அழிந்த ஆண்டு; Malayalam: കൊല്ലം അഴിഞ്ഞ ആണ്ട്), literally translating to "The Year Kollam Was Destroyed," refers to a significant chronological and historical marker in South Indian history. It identifies the year 1002–1003 CE (approximately 199 of the Kollam Era), marking the conquest and subsequent destruction of the port city of Kollam by the Chola Empire under Rajaraja Chola I.^[1] This thrust was probably led by the Chola general Naralokavira Kalinga Rayan. A new era, known as "Kollam Azhintha Andu", perhaps commemorating this victory, was inaugurated by the Pandyas in 1097 AD.^[2]

During the late 10th and early 11th centuries, the Chola-Chera Wars were a series of conflicts between the Chola Dynasty of Tanjore and the Chera Perumals of Mahodayapuram (present-day Kerala). Kollam was a vital strategic asset—a flourishing international trade hub and the capital of the Venad kingdom (a southern feudatory of the Cheras). To secure a monopoly over the Arabian Sea trade routes and punish the Cheras for their alliance with the Pandyas, Rajaraja Chola I launched a massive military expedition toward the west coast.^{[3] [4]}

The phrase is rooted in Chola panegyrics (Meikeerthis) and inscriptions, most notably the Senur Inscription. Historical records indicate that the Chola navy and army successfully breached the defenses of Kollam. The term "Azhintha" (destroyed/sacked) suggests a scorched-earth policy where the city’s fortifications or commercial centers were razed to diminish its power. This victory gave Rajaraja the title Kandalur Salai Kalamarutta, signifying his triumph over the Chera navy at Kandalur and the subsequent fall of Kollam and Kodungallur. In ancient Tamil and Malayalam astronomical and administrative records, "Kollam Azhintha Andu" was occasionally used as a reference point for dating events. It is often contrasted with the Kollam Andu (the Kollam Era, which started in 825 CE).^[5]
