 While this regiment could have been named after "Pazhi Ili" of the Mutharaiyar clan, the occurrence of the term "Ainnurruvar" is curious.These armies were evidently lent in support of the Chola expeditions.Contrary to the earlier view that the purpose of Rajendra's expedition to South East Asia may have been to plunder, the more recent view which is also supported by available evidence is that the raids were conducted to clear piracy from and to gain control over the sea lanes of the Melakka Straits that served as the gateway to the Far East for the Indian merchant ships.
