A small number of Italian and German states introduced an age of consent in the 16th century, setting it at 12 years. Towards the end of the 18th century, other European countries also began to enact age of consent laws. The first French Constitution established an age of consent of 11 years in 1791, which was raised to 13 in 1863. Portugal, Spain, Denmark and the Swiss cantons, initially set the age of consent at 10–12 years and then raised it to between 13 and 16 years in the second half of the 19th century.[5] Historically, the English common law set the age of consent to range from 10 to 12.[6]

In the United States, by the 1880s, most states set the age of consent at 10–12, and in one state, Delaware, the age of consent was only 7. A New York Times article states that it was still aged 7 in Delaware in 1895.[7] Female reformers and advocates of social purity initiated a campaign in 1885 to petition legislators to raise the legal age of consent to at least 16, with the ultimate goal to raise the age to 18. The campaign was successful, with almost all states raised the age of consent to 16–18 by 1920.[8][9]
