Age of consent within the last 100 years.

In the USA last century, the age of consent was 10 years old. California was the first state to change the age of consent to 14, which it did in 1889. After California, other US states joined in and raised the age of consent too. (Source:http://www.ageofconsent.com/comments/numberone.htm)

As for the reasons why we age of consent just seems to get higher and higher, Essentially, we need more education just to survive in today's society, and this takes much more time. This additional education we need to function in today's society seems to me to be the main cause of the increase in the age of consent in many 20th century societies. The Common Law age of consent was 10. The French penal code raised the age from 11 to 13 only a century ago. In England, it was only in 1929 (70 years ago) that the ancient Christian minimum age for the marriage of females, which was 12, was abandoned. The early rock and roll singer Jerry Lee Lewis was considerably older than his 13 cousin whom he married in all legality in Arkansas. Since then, the age there has been raised to 16. That marriage lasted for about 15 years and there was never any other "scandal" associated with Jerry Lee Lewis. The story is quite different, however, for his cousin Jimmy Swaggart (the well-known and disgraced tele-evangelist) who married a woman his own age but later publicly confessed that he was an adulterer.

In the seventh century, 3 year old girls were burned to death or tortured in Europe for copulating with demons, witches and sorcerers. Strong sexual passions were attributed to the youngest children. Even Jean Bodin, one of the greatest legal authorities of his time, said that the appropriate age of consent for a female was 6. (I do not mean to suggest that 3 year olds did in fact have sexual relations with demons. It is however interesting to see that at that time it was publicly believed that child-adult relations were the fault of seductive children who sought out mature men rather than today's popular belief that it is instead pedophiliac adults who prey on innocent, unsuspecting children.)

In the US (an example of a prominent western country, since the west had the greatest effect on the world in the last couple of centuries.) They considered a seven year old female competent on making decisions regarding sex, though it was raised later on (in 1886, after attempts to raise the age of consent, Delaware was the only state to retain the common law age of seven, while twenty five states set the minimum age at a mere ten.) In older times, children were not perceived in the same sense that we perceive them, but the perception was changed gradually, which is due to a great extent to industrialization, and of course sigmund freud and others came along with their theories and supported these changes in social thinking (the word adolescent itself was introduced as recently as 1904.)
