What is India's caste system? Is it contentious in U.S.?

Caste is an ancient system of social hierarchy based on one’s birth that is tied to concepts of purity and social status. Its history, evolution and current state are complicated.

A move to outlaw caste-based discrimination in Seattle has thrust this complex — and often misunderstood — system into the spotlight. If the Seattle City Council votes Tuesday to approve an ordinance that will include caste in its anti-discrimination laws, Seattle will become the first city in the United States to outlaw such discrimination.

While the definition of caste has evolved over the centuries, under both Muslim and British rule, the suffering of those at the bottom of the caste pyramid – known as Dalits, which in Sanskrit means “broken” — has continued.

The word “caste” has its origins in Latin (castus), which means chaste or pure. Caste made its way into the Indian lexicon with the arrival of the Portuguese in the 1700s who first used the word “casta” with reference to the social hierarchy in the Indian subcontinent.
