all regions of Greece and throughout Greek communities abroad, the membership numbered in thousands. Among its members were tradesmen, clergy, Russian consuls, Ottoman officials from Phanar and revolutionary Serbs, most notably, the leader of the Serbian Revolution, father of the modern Serbia and founder of the Karadjordjevic dynasty Karageorge Petrovic. Members included primary instigators of the Greek revolution, notably Theodoros Kolokotronis, Odysseas Androutsos, Dimitris Plapoutas, Papaflessas and the metropolitan bishop Germanos of Patras. Hierarchy and initiation Filiki Eteria was strongly influenced by Carbonarism and Freemasonry. The team of leaders made and spread its decisions, saying that they transmitted the commands of an "Invisible Authority" (Αόρατος Αρχή), who was thought to be one or more strong persons, so that from the start it was shrouded in mystery, secrecy and glamour.

Commands were carried out unquestioningly and members did not have the right to make decisions. Members of the society came together in what was called a "Temple" with four levels of initiation: a) Brothers (Αδελφοποίητοι) or Vlamides (Βλάμηδες), b) the Recommended (Συστημένοι), c) the Priests (Ιερείς) and d) the Shepherds (Ποιμένες). The Priests were charged with the duty of initiation. When the Priest approached a new member, it was first to make sure of his patriotism and catechize him in the aims of the society; the last stage was to put him under the lengthy principal oath, called the Great Oath (Μέγας Όρκος). Much of the essence of it was contained in its conclusion: When the above was administered the Priest then uttered the words of acceptance of the novice as a new member: Afterwards the initiated were considered neophyte members of the society, with all the rights and obligations of this rank. The Priest immediately had the obligation to
