First American pope elected and will be known as Pope Leo XIV

In his time around the end of the 19th century, Leo XIII was known as the “Social Pope” and “Pope of the Workers”. He wasn’t a radical but opened the door to modern thinking in the church.

Presumably there’s some symbolism to why the new pope wanted to adopt this particular name.

Popes usually go for symbolic names, so the Leo XIII connection seems unavoidable.
