Interparliamentary Assembly on Orthodoxy
The Interparliamentary Assembly on Orthodoxy (, ), or I.A.O., is a transnational, inter-parliamentary institution that in 1994 was established as European Interparliamentary Assembly on Orthodoxy (EIAO).

Based in Athens, Greece, the Interparliamentary Assembly on Orthodoxy constitutes a permanent communication structure between parliamentarians of the members' states aiming at unity in diversity of Orthodox Christians on the basis of the principles and values of Christianity and democracy.

History

Inspired by a conference held from 30 June to 4 July 1993 in Chalkidiki on the topic of "Orthodoxy in the New European Reality", the European Interparliamentary Assembly on Orthodoxy was formed on initiative of the Hellenic Parliament. Following the 1993 Manifesto of the Participants, the official Founding Act was passed by the participants of the Founding Synod held in November 1994 in Athens. After in 2001, groups of MPs from Australia, Asia, Africa and the U.S.A. participated in the General Assembly, the organization was then renamed Interparliamentary Assembly on Orthodoxy (I.A.O.).

During the 2004 General Assembly in Kiev, Ukraine, in June 2004, it was decided to seek cooperation with the Parliamentary Union of the Organisation of Islamic Cooperation (P.U.I.C.). A co-operation agreement was drafted at an Athens meeting of the two organizations on March 22, 2005. On 19 May 2010, a cooperation agreement with the Pan-African Parliament was signed by PUIC's President Idriss Ndele Moussa and I.A.O.'s Secretary-General Anastasios Nerantzis

Massive protests broke out during the 2019 General Assembly in Tbilisi, Georgia, after the chairman of the assembly, a Russian communist named Sergei Gavrilov, made a number of public statements that were viewed by the Georgian public as denigrating Georgian sovereignty.
