About Pope Leo XIII

Pope Leo XIII, born Vincenzo Gioacchino Raffaele Luigi Pecci, reigned as the 256th Pope from 1878 until his death in 1903. His historical importance, reflected in his Pantheon HPI Rank of #173, stems from his extensive efforts to address the modern world's challenges from a Catholic perspective. He was a significant figure in modernizing the Church's social doctrine, notably through his 1891 encyclical Rerum Novarum, which addressed the condition of the working classes and laid groundwork for Catholic social teaching on labor and capital.

Despite this profound historical weight, Pope Leo XIII's contemporary internet attention appears disproportionate. With 2.4 million Wikipedia views in 2025, he is receiving what this analysis terms an "overattention" gap of +5x relative to his historical ranking. This suggests he is significantly more prominent online than his comparable historical influence might predict. For context, figures like Robin Williams (#966 importance) garnered 5.5 million views, though Leo XIII's 2.4 million views are still substantial for a 19th/20th-century religious leader.

Furthermore, his online presence is currently surging, evidenced by a remarkable 646.1% year-over-year increase in views and positive Q1-to-Q3 momentum of +10%, indicating a recent spike in public or academic interest driving current search traffic.
