Well done Walrus on 17th and 20th Centuries ... notes:

1600-1700 - FALSE - The Stationers Company were incorporated in 1557, though the guild had achieved an effective monopoly of printing by 1556 (except for books specifically licensed by the crown). The first Copyright Act of 1710 removed their monopoly but continued to allow them to charge for registering copyrights.

1900-2000 - TRUE - In 1944, Helen Duncan, a medium, was found guilty in a seven-day trial at the Old Bailey of offences under the Witchcraft Act of 1735 and jailed for nine months for "pretending to raise spirits of the dead". The Act had not been used for more than a century. The Act was repealed in 1951, and replaced by the Fraudulent Mediums Act. Under this act, it is still illegal to purport to use clairvoyant or telepathic powers or to purport to act as a spiritualistic medium, especially if money is taken as a reward or payment.

Also Sibelius for 11th Century exposition ...

1000-1100 - FALSE - There were several further successful invasions (though not by foreign powers), including those by Henry VII and William III. It is true that the official language of English courts was French until 1362 ("The Statute of Pleading", 1362 allowed pleas in English). Acts of parliament continued to receive the assent in French into the 19th Century.

and Raedwulf for 12th Century ...

1100-1200 - TRUE - A form of the game was recorded circa 1100 (West Ham beat Newcastle 2-0, I think, so some things do change). In subsequent centuries football became so popular that various English monarchs, including Edward III and Henry VI, forbade the game because it took interest away from the military sport of archery.

Does anyone have any further comments on 1300-1400 and 1400-1500?

The only other outstanding item is 1700-1800. Any takers?

:-)
