On August 28, 1918, the Persian Embassy in Istanbul on behalf of Persia presented a letter expressing a note of protest against the creation of a state called “Azerbaijan”.
The letter said:
“The Embassy of Persia, Istanbul.
Dear Foreign Ministry,
As a result of the Russian-Ottoman peace treaty, a state called ‘Azerbaijan’ is being implemented in the Caucasus.
Given the fact that a region with such a name with a center in Tabriz exists within the borders of the state of Persia and that no state with such a name has ever existed, Persia is dazed and sees the need to revise this decision.
August 28, 1918.“
