The caste systems in Sri Lanka are social stratification systems found among the ethnic groups of the island since ancient times. The models are similar to those found in Continental India, but are less extensive and important for various reasons, although the caste systems still play an important and at least symbolic role in religion and politics. Sri Lanka is often considered to be a casteless or caste-blind society by Indians. The caste systems of Sri Lanka were historically not tied to the religious establishment but rather a tool to service the ruling elite - a model more reminiscent of feudalism in Europe. At least three major, parallel caste systems exist in Sri Lankan society: Sinhalese, Sri Lankan Tamil and Indian Tamils. A universal welfare system that focused on providing education for everyone regardless of background has provided people from lower caste groups similar opportunities to enter jobs previously only frequented by those in upper-caste groups, with younger generations mostly rejecting any pressure to conform to caste-related jobs. The Civil War has also broken down caste barriers as they were seen as an obstacle toward ethnolinguistic unity. The caste system of the Sinhalese and Sri Lankan Tamils display some similar traits, where both systems having comparable castes with similar occupations and status. The interior arable land is largely dominated by the Govigama caste under the Sinhalese and by the Vellalar under the Sri Lankan Tamils, who are traditionally involved as husbandmen and form approximately half the population of their respective ethnicities. The peasants under them are the Sinhalese Bathgama and Tamil Pallars. The coastal land is dominated by the Karavas under the Sinhalese and the Karaiyar under the Tamils. Both castes share a common origin with background in seafaring, trade and warfare. The artisans were collectively known as Navandanna by the Sinhalese and as Kammalar by the Tamils. They constituted of respective endogamous castes traditionally involved as blacksmith, goldsmith, coppersmith, carpenters and stonemasons.
