Assam silk denotes the three major types of indigenous wild silks produced in Assam—golden muga, white pat and warm eri silk. The Assam silk industry, now centered in Sualkuchi, is a labor-intensive industry. History Assam was well known for the production of high quality silk since ancient times. The craft of weaving goes along with the production of silk. It grew to such sophistication in Assam that it was known all over India and abroad. In the Kishkindha Kanda of Ramayana, it is stated that one travelling towards the east has to first pass through Magadha, Anga, Pundra and then the Kosha-karanam-bhumi ("the country of cocoon rearers"). Kautilya’s Arthashastra, a political literature of the 3rd century BC, makes references to the highly sophisticated silk clothing from Assam. Kautilya mentions the production of Suvarnakudyaka (from Kamrupa) along with Vangika (from Vanga/southern Bengal), Magadhika (from Magadha) and Paundrika (from Pundra/northern Bengal), of which Suvarnakudyaka, Magadhika and Paundrika fabrics were types of Kauseya (Tussar/Muga) and Cina-patta (Mulberry silk). The fact that Kamrupa produced Suvarnakudyaka is confirmed by the 8th-century writer Kumārila Bhaṭṭa who, in his commentary of Arthashatra, said that Kamrupa was Suvarnakudya(Kamarupeschaiva Suvarna Kudyah). As per the Arthashatra, the fibres of Suvarnakudyaka were of 'the colour of butter', 'as red as the sun', and of the best quality. Due to this description of colour, the type of silk can be easily identified as Muga. The text also refers to four trees (Vakula, Likucha, Vata and Naga-vriksa) which the silkworms feed on. Out of these, Vakula and Naga-vriksa<ref>Journal Of Bihar And Orissa Research Society Vol. 3, p.215, "There is some doubt in identifying the Naga tree named in the Arthashastra. Lexicographers take it to denote the tree, Naga-kesara and Punnaga, the flowers of which possess yellow anther..A synonym of Naga-kesara is Champeya, because the flower of Champaka (Michelina champac) is yellow; and it is no less remarkable that the Champa silk once celebrates in Assam was fine white." p. 212, "There is a variety of muga called Champa muga, its worms feeding on leaves of Champa tree (Michelia champaca). Sir George Watt tells us that "the Chpa silk seems almost quite forgotten to-day, but it was the fine white silk worn by the kings and nobles of Assam in former times"."</ref> belong to the genus Ericales and Magnolia which the Muga silkworm Antheraea assamensis is known to feed on; while Likucha (Artocarpus lakucha)
