In Britain it is the law that every male between the ages of 10 and 18 years old must meet on a Sunday morning at the village green to perform archery?

Answer 1

There was a law requiring people to practice archery

But 3 H.8.c.3 was repealed by the Statute Law Revision Act (26 & 27 Vict.c.125) [this was a law to tidy up and remove a whole range of obsolete laws].

I presume, but am not certain, that this also repealed sections 1 to 4 and 7 to 10 of 33 H.8.c.9. The whole of the latter was repealed by the Betting and Gaming Act (1960 c.60). So: The law requires all Englishmen to practice archery.

It did so once upon a time. It stopped doing so in 1863.

It definitely stopped doing so in 1960.

Answer 2

It WAS the law in the later Middle Ages. If the law is still in force, it certainly has not been enforced for many centuries.
