La Liga title race over 95 years: From open competition to one-club dominance to a two-horse race
Inspired by this post stating the total number of titles and this video showing the evolution of the cumulative number of titles, I decided to just put the data as an easy to digest graph.
Looking at the graph I can identify three phases. From its start to the late 50s it was quite a competitive league. Then between the early 60s to the end of the 80s it was mostly Real Madrid's own competition. Last, from the 90s onwards, Barcelona showed up and outpaced Real Madrid to narrow a gap in tiles that reached a 15 in 1989 (7 now).
