What 2 countries showed spheres of influence in Persia since 1907?

The Anglo-Russian Entente was an agreement of 1907, in which Great Britain and the Russian Empire appeased their colonial disputes over Persia, Afghanistan and Tibet. It was signed during the Anglo-Russian Agreement.

It delineated the spheres of influence in Persia, stipulating that no country should interfere in the internal affairs of Tibet and recognizing the control of the British over Afghanistan. This agreement induced the formation of the Triple Entente.

First it is important to understand what a sphere (s) of influence means. It is an outside influence from another country (or more than one) that claims exclusive rights to a region of a different country.

In Persia, Russia and the British Empire established spheres of influence through the Anglo-Russian Convention of 1907. Neither were interested in Persia itself, but where it was strategically located.

The British Empire wanted to protect India from Russian expansion in the area, and Persia was close by.

The Russians were expanding in that area and seizing parts of Persia.

They made an agreement to control different spheres of influence in Persia (Britain the east and Russia the north).
