Most Nairs have the name of his maternal Tharavadu affixed to his name. Along with that, surnames are added to the names for further identification of the lineage. Several surnames are found among Nairs. Some surnames were conferred by the Kings for deeds of valour and services. Rajas of Cochin conferred on the Nairs the titles of nobility such as Achan, Kartha, Kaimal and Mannadiar. The title,Menon is used by the Nairs of Malabar and Cochin areas. The southern kingdoms of Venad (later extended as Travancore), Kayamkulam, Thekkumkur and Vadakkumkur conferred the titles such asPillai, Thampi, Unnithan, and Valiathan on distinguished Nair families. Panikkar and Kurup were the titles of Nairs who maintained martial schools known as Kalaries. Surnames like Nambiar, Nayanar,Kitavu, and Menokki are seen only in North Kerala, where as “Nair” is a surname which is ubiquitous through out Kerala.
Middle age South Indian history, historians, and foreign travelers referred to the Nairs as a dignified martial nobility. The earliest reference to Nairs comes from the Greekambassador Megasthenes. In his accounts of ancient India, he refers to the “Nayars of Malabar” and the “Kingdom of Chera”. Irrespective of the different theories that seek to explain the origin of Nairs, it is clear that till the early 20th century, Nairs exerted their influence in medieval Kerala society as feudal lords and owned large estates. The position in society of the Nairs as that of a martial nobility in medieval Kerala has been likened to the position in society of the Samurai in medieval Japan. Nairs dominated the civil, administrative and military elite of the pre-British era in Kerala.
The decline of Nair dominance came about in multiple stages. During colonial times, the British perceived that Nairs were an inherent threat to their hegemony in the region and therefore outlawed their right to bear weapons and by banning the Kerala martial art ofKalaripayattu. Weapons were integral to the Nair psyche and power, and combined with repressive legislation led to a loss of social standing for Nairs, though some of the social legislation was in part inspired by the Nairs themselves, such as changes in inheritance law permitting the Karanavan to pass on some (and later all) of the fruits of his stewardship of the taravad to his own children. During post-colonial years, the Land Reforms Ordinance of 1950’s led to massive loss of land-ownership by Nair feudal lords and some Nair landed gentry were relegated to poverty overnight.
The Nair Brigade was the army of the erstwhile kingdom of Travancore in India. Nairs were a warrior community in the region which was responsible for the security of Travancore and other local kingdoms. King Marthanda Varma’s (1706–1758) personal bodyguard was called ‘Thiruvithamkoor Nair Pattalam’ (Travancore Nair Army). The Travancore army was officially referred as the Travancore Nair Brigade in 1818. Since independence, Malabar has been the most important recruitment ground for theMadras Regiment and Nairs constitute a huge proportion of the recruits from this area. Although not as famous as Malabar Nayars, Nayars from Travancore and Cochin also constitute a significant portion of the Madras Regiment. Two former Travancore state army divisions, the 1st Travancore Nayar Infantry and the 2nd Travancore Nayar Infantry were converted in to 9th and 16th Battalions of Madras Regiment respectively after the independence. The Nayar army from Cochin was refurbished in to the 17th Battalion.
