Pope Gregory XIII

About Pope Gregory XIII

Pope Gregory XIII, born Ugo Boncompagni in 1502, was a pivotal religious figure of the late Renaissance, holding the papacy from 1572 until his death in 1585. His historical importance, reflected by his Pantheon HPI Rank of #477, is primarily secured by the Gregorian Calendar reform. Recognizing the inaccuracies of the Julian calendar, especially its drift relative to the vernal equinox, he introduced the new system, which remains the internationally accepted civil calendar today, marking a profound, long-lasting impact on global timekeeping and religious observance.

Despite this fundamental contribution to global cultural infrastructure, Pope Gregory XIII's modern digital footprint appears relatively modest. In 2025, his Wikipedia page garnered 152K annualized views, placing him in a significant attention gap relative to his historical rank, categorized as receiving approximately -3x the attention expected. For comparison, Ignatius of Loyola, a contemporary religious figure with a slightly lower importance rank of #555, attracted over three times the attention with 485K views in the same year.

Interestingly, while his overall attention is low, the data suggests a slight positive trend in recent interest, with his 2025 pageviews showing an 18.6% year-over-year increase. However, this momentum appears to be fading across the year, as the comparison between Q1 and Q3 pageviews shows a notable -27% drop in sustained interest.
