The Sangam literature (Tamil: சங்க இலக்கியம், caṅka ilakkiyam), historically known as 'the poetry of the noble ones' (Tamil: சான்றோர் செய்யுள், Sāṉdṟōr Seyyuḷ), connotes the early classical Tamil literature and is the earliest known literature of South India. The Tamil tradition links it to legendary literary gatherings around Madurai in the ancient Pandya kingdom. It is generally accepted by most scholars that the historical Sangam literature era, also known as the Sangam period, spanned from c. 100 BCE to 250 CE, on the basis of linguistic, epigraphic, archaeological, numismatic and historical data; though some scholars give a broader range of 300 BCE to 300 CE.
The Eighteen Greater Texts (Patiṉeṇmēlkaṇakku), along with the Tamil grammar work Tolkappiyam, are collectively considered as Sangam literature. These texts are classified into the Ettuttokai (Eight Anthologies) and Pattupattu (Ten Idylls). They encompass both Akam (interior) themes, focusing on personal emotions and love, and Puram (exterior) themes, emphasizing heroism, ethics, and societal values. Notable works include Akananuru (400 love poems), Purananuru (400 heroic poems), Kurunthogai (short love poems), and Natrinai (poems set in five landscapes). The Pattuppāṭṭu highlights specific regions and rulers, with works like Malaipadukadam and Perumpanarrupadai serving as guides to wealth and prosperity.
