Today, President Erdogan of Turkey brought forth a document that makes the claim that the Iraqi city of Mosul is actually Turkish soil.
According to this Kurdish news site:
ISTANBUL, Turkey (Kurdistan24) – Turkey’s President Recep Tayyip Erdogan invoked on Monday an early 20th-century irredentist document that claimed the Iraqi city of Mosul as Turkish soil.
Erdogan’s remarks came amid the commencement of a long-anticipated operation by the Iraqi Army, Kurdistan’s Peshmerga Forces and the US-led Coalition to liberate Mosul from the Islamic State (IS).
In Mosul “a history lies for us. If the gentlemen desire so, let them read the Misak-i Milli (National Oath) and understand what the place means to us,” Erdogan declared.
The Turkish president referred to an Ottoman Parliament-sealed, 1920 pact that designates Kirkuk and Mosul as parts of Turkey.
This may help to explain why the Iraqi government has been making repeated requests for the Turks to leave the area.
