Derived from an ancient Celtic unit and adopted by the Romans as the ''leuga'', the league became a common unit of measurement throughout western Europe. It may have originally represented, roughly, the distance a person could walk in an hour. Since the Middle Ages, many values have been specified in several countries.

, where its exact meaning varies. * ''Legua nautica'' (nautical league): Between 1400 and 1600 the Spanish nautical league was equal to four Roman miles of 4,842 feet, making it 19,368 feet (5,903 metres or 3.1876 modern nautical miles). However, the accepted number of Spanish nautical leagues to a degree varied between 14 1/6 to 16 2/3, so in actual practice the length of a Spanish nautical league was 25,733 feet (4.235 modern nautical miles) to 21,874 feet (3.600 modern nautical miles) respectively. * ''Legua de por grado'' (league of the degree): From the 15th century through the early 17th century, the Spanish league of the degree was based on four Arabic miles. Although most contemporary accounts used an Arabic mile of 6 444 feet (1,964 metres), which gave a Spanish league of the degree of 25,776 feet (7,857 metres or 4.242 modern nautical miles) others defined an Arabic mile as just 6,000 feet making a Spanish league of the degree 24,000 feet (or 7,315 metres, almost exactly 3.95 modern nautical miles).S''pence's Guide to Shipwreck Research'', by Dr. E. Lee Spence, Narwhal Press, Charleston/Miami, © by Edward L. Spence, 1997, p. 32 * ''Legua geographica'' or ''geográfica'' (geographical league): Starting around 1630 the Spanish geographical league was used as the official nautical measurement and continued so through the 1840s. Its use on Spanish charts did not become mandatory until 1718. It was four millias (miles) in length. From 1630 to 1718 a millia was 5,564 feet (1 696 metres), making a geographical league of four millias equal 22,256 feet (6,784 m or 3.663 modern nautical miles). But from 1718 through the 1830s the millia was defined as the equivalent of just over 5,210 feet, giving a shorter geographical league of just over 20,842 feet (6,353 m or 3.430 modern nautical miles). * ''Legua marítima'' (maritime league): From around 1840 through the early 20th century, a Spanish marine league equaled 18,263.52 feet (5,566.72 metres or 3.00579 modern nautical miles).
