Before there was one Meitei nation, there were seven independent kingdoms. Seven peoples. Seven kings. Seven totems. United by one law — and one god.
In Meitei society, you cannot marry within your own clan. This single law — called Yekthoknaba — has held all seven clans together for over 2,000 years. Your clan is written not just in your name, but in your DNA — in the Y-chromosome passed father to son, unchanged, back to a single divine ancestor.

The Meitei Yek Salai system has a direct parallel in modern genetics. Each Salai contains hundreds of yumnak (surnames) that can trace their male line back to a single legendary ancestor. Because the Y-chromosome is passed almost exclusively from father to son with very little change, all males within a single Salai share a nearly identical Y-chromosome haplotype — a genetic signature that traces back thousands of years to a common ancestor.
This means your clan is not just a social label. It is a biological record of who your people were — preserved in your body, unchanged, across 2,000 years of history.
