Throughout the 19th Century, the Great Powers had different aims over the "Eastern Question", the integrity of the Ottoman Empire. Russia wished for access to the "warm waters" of the Mediterranean and followed a pan-Slavic foreign policy, supporting Bulgaria and Serbia. Britain wished to deny Russia access to the "warm waters" and supported the integrity of the Ottoman Empire, though it also supported a limited expansion of Greece as a backup plan in case integrity of the empire was no longer possible. France wished to strengthen her position in the region, especially in the Levant. Austria-Hungary wished for a continuation of the existence of the Ottoman Empire, since both were multinational entities ruled by a small elite and thus the collapse of the one would affect the other as well. Also, in the eyes of the Habsburg Empire, with its large Serbian and Croatian populations, the strengthening of Serbia was highly undesirable. While it has been argued that Italy from that time already wished to recreate the Roman empire, her main aim at the time seems to have been primarily the denial of access to the Adriatic Sea of another major sea power. Germany in turn, under the "Drang nach Osten" policy, aspired to turn the empire into its own de-facto colony, and thus supported its integrity.
