A controversy in the US state of California concerning the portrayal of Hinduism in history textbooks began in 2005. The protest was led by Vedic Foundation (VF) and the American Hindu Education Foundation (HEF) by complaining to the California's Curriculum Commission, saying the coverage in sixth grade history textbooks of Indian history and Hinduism was biased against Hinduism; and points of contention includes a textbook's portrayal of the caste system, the Indo-Aryan migration theory, and the status of women in Indian society as the main features of Hinduism.
