As a result, Ottoman holdings in Europe declined sharply; Bulgaria was established as an independent principality inside the Ottoman Empire, but was not allowed to keep all its previous territory. Bulgaria lost Eastern Rumelia, which was restored to the Turks under a special administration; and Macedonia, which was returned outright to the Turks, who promised reform. Romania achieved full independence, but had to turn over part of Bessarabia to Russia. Serbia and Montenegro finally gained complete independence, but with smaller territories.
