Competition
The Terceira Divisão was established in 1948 and in its last season had 7 Sections with the Championship of each being divided into two phases. The 6 Sections (A, B, C, D, E, F) within Mainland Portugal each had 12 teams and played 22 matches in the first phase. This was followed by the second phase where the top 6 teams in each section competed in the Promotion Group and played 10 matches to determine the champion teams from each Group that would be promoted to the Segunda Divisão. The last 6 teams in each Section competed in the Relegation Group and played 10 matches to determine the last 3 teams to be relegated to the District Leagues. In the Azores Section there were 10 teams that played 18 matches in the first phase. This was followed by the second phase where the top 4 teams in the Section competed in the Promotion Group and played 6 matches to determine the champion team that would be promoted to Segunda Divisão. However, limitations were placed on promotion to the Segunda Divisão dependent upon the position of the 6 teams from Azores competing in the Second Division Championship. If no teams from Azores finished in a relegation position in Second Division then the lowest-placed team played a two-leg play-off with the winners of the Third Division Azores Section to determine the remaining team from Azores that would compete in the Second Division. The last 6 teams in the Section competed in the Relegation Group and played 10 matches to determine the last 3 teams to be relegated to the District Leagues.Seasons - League Tables
