What were the interests of Great Britain, France and Russia in the Eastern Question?

The Eastern question arose even during the reign of Alexander 1. At this time, the prerequisites for the destruction of a single state began to appear in the Ottoman Empire. European countries, namely Great Britain and France, were interested in obtaining territories in order to expand their sales markets and spheres of influence in the east. Russia initially sought to provide assistance to the Christian peoples that were part of Turkey, but territorial interests were also defended in the course of numerous wars with the Ottoman Empire.
