The last-placed team in the competition is relegated at the end of the season to the División de Honor B, Spain`s second level of men's rugby union.
The División de Honor season takes place between September and May, with every team playing each other home and away for a total of 22 matches.
There were various attempts to relaunch it, but none bore fruit until the 1969-70 season, when the National Rugby League was created.
The following scrollable table shows the teams' final league positions in each season.
The playoff champions - not necessarily the team finishing first in the league - are highlighted in gold, except in 1979 when the championship was shared.
