Editing Scottish Football League (section)

===Split into divisions===

The league proved to be highly successful, and in 1893, a second tier was formed by the inclusion of a number of clubs previously in the [[Scottish Football Alliance]]. Promotion was initially based on a ballot of clubs; automatic promotion was not introduced until 1922.

The onset of [[World War I]] saw Division Two but not Division One being suspended, not restarting again until 1921 when the [[Central Football League]] was absorbed as a new division with automatic promotion.

'''Note:''' in contemporary sources the divisions were often referred to as 'First' and 'Second' rather than 'One' and 'Two'; the latter format has been used throughout the site to avoid confusion with the league's [[Scottish Football League First Division|First]] and [[Scottish Football League Second Division|Second Division]], each one tier lower than their predecessor, introduced in the 1970s (see below).
