Pope Francis, the 266th pope of the Roman Catholic Church, will be mourned and buried at the Basilica of Saint Mary Major after dying one week ago at 88 years old.

Vatican protocol demands that those attending the papal funeral wear a black suit and a black tie. Trump was seen at the event wearing a blue suit and a blue tie. Biden, Zelenskyy also made protocol missteps.

With delegations from about 130 countries present at Pope Francis' funeral, the seating chart needed to be organized accordingly.
