In 1994, as part of reconstruction to allow the admission of Inverness Caledonian Thistle and Ross County to the league, the SFL was recalibrated to give four divisions of 10 teams.
In 2013, the SFL and SPL merged to form the Scottish Professional Football League (SPFL).
The SPFL named its fourth tier as Scottish League Two, which effectively replaced the Third Division.
From 2005 until 2013, only the champion was automatically promoted to the Second Division at the end of each season.
The clubs that finished 2nd, 3rd and 4th entered a play-off with the 9th placed team of the Second Division.
