The age of consent laws in the UK trace back to the 13th century when the first age of consent was set at 12 years old. Over time, the age of consent was raised to 16 through various legislative changes. In 1875, the Offences Against the Person Act raised the age to 13, and ten years later, the Criminal Law Amendment Act 1885 further increased it to 16. https://lawforeverything.com/age-of-consent-uk/
