How Far Is a League and Where Did the Unit of Measurement Come From?

Folk tales refer to a league as a specific distance.

There were seven-league boots, and Jules Verne sent Captain Nemo twenty thousand leagues under the sea.

A league is an ancient measurement.

In medieval England it was simply the distance a person or a horse could walk in one hour, which is about three miles, or five kilometres, the same distance as defined by the Romans.

The league is no longer an official unit of measurement in any nation.
