Seiks (pron. Seeks).
A religious sect in Hindustan, founded in 1500. They profess the purest Deism, and are distinguished from the Hindus by worshipping one invisible god. The word means lion, and was applied to them on account of their heroic resistance to the Moslem. Ultimately they subdued Lahore, and established a military commonwealth in the Punjab, etc.
In 1849 the Punjab was annexed to the British empire.
