Gaddafi also wanted to combat the strict social restrictions that had been imposed on women by the previous regime, establishing the Revolutionary Women's Formation to encourage reform. In 1970, a law was introduced affirming equality of the sexes and insisting on wage parity. In 1971, Gaddafi sponsored the creation of a Libyan General Women's Federation. In 1972, a law was passed criminalizing the marriage of any females under the age of sixteen and ensuring that a woman's consent was a necessary prerequisite for a marriage.
