Kyrill I.
Pope Francis is recognised for his efforts "to further close the nearly 1,000-year estrangement with the Orthodox Churches". His installation was attended by Patriarch Bartholomew I of Constantinople of the Eastern Orthodox Church, the first time since the Great Schism of 1054 that the Eastern Orthodox Ecumenical Patriarch of Constantinople has attended a papal installation. On 12 February 2016, Pope Francis and Patriarch Kirill of Moscow, head of the largest Eastern Orthodox church, met in Havana, Cuba, issuing a joint declaration calling for restored Christian unity between the two churches. This was reported as the first such high-level meeting between the two churches since the Great Schism of 1054.
