Pope 225
Pius V
The 225th pope in the Holy See's list of Supreme Pontiffs, serving as Bishop of Rome from 7, 17.I.1566 to 1.V.1572. His secular name is listed as Antonio (Michele) Ghisleri. The Holy See lists his birthplace as Bosco (Alessandria).
Why this pontificate matters
Pius V belongs to the post-Reformation Catholic response. His importance is not just that he appears in sequence, but that his pontificate sits inside reform, liturgy, discipline, and confessional boundary-making after Trent.
The Reformation era is better explained through context than by adding visual branches to the pope line.
A future layer could connect councils and major reforms around these pontificates.
