About Spanish Tercera Federación Group 4
Tercera Federación, previously known as Tercera RFEF, is the fifth tier of the Spanish football league system. It is below the La Liga, Segunda División, and its fellow semi-professional divisions Primera Federación and Segunda Federación. It was founded in 1929 as the third tier, and dropped down to the fourth and fifth tiers in 1977 and 2021, respectively.
On 6 May 2020, the RFEF announced the creation of a new, two-group, 40-team third division called Primera División RFEF, which made the former third and fourth divisions, Segunda División B and Tercera División, respectively, to drop down a level and change into Segunda División RFEF and Tercera División RFEF; the changes were made effective for the 2021–22 campaign.
In July 2022, the division was renamed Tercera Federación.
