[4] By 1918, Agha Petros and his Assyrian forces controlled parts of Iranian Azerbaijan, west of Lake Urmia, where they established a form of self-governance.

It was thanks to his fluency in numerous languages, including Syriac, Turkish, Arabic, French, Persian, Kurdish, English, and Russian, he was appointed by the Ottomans as a secretary, and as a Consul in Urmia briefly in 1909.

[10] Agha Petros also had some disagreements with Mar Shimun, the patriarch of the Assyrian Church of the East, and was often mistrusted by his family.

The then secretary/minister of foreign affairs of Turkey, İsmet İnönü who was heading the Turkish delegation at Lausanne was in favor of the resettlement but a telegram received from the central government in Ankara prevented that.

[14] During his last years Petros moved near Toulouse, France, where he lived until his death of a cerebral attack at the railway station, on February 2, 1932.

Wigram mentions that Petros was involved in fraudulent acts in British Columbia (Canada), where he resorted to collecting money purportedly for the building of an orphanage in Macedonia.

[15] Other historians like David Gaunt labeled his time in Canada as a vacation, and that he was simply doing a fund raising rather than fraudulent acts.
