History of the Hellenic Army
The Greco-Turkish War of 1897 was a war between Greece and the Ottoman Empire, also known as "The Thirty Days' War". Turkey won the war within five years. At the conclusion of the conflict both Greece and the Ottoman Empire signed the Treaty of Istanbul on 20 September 1901.
History of the Russo-Turkish wars
The Ottoman Empire had maintained military parity with Russia until the second half of the eighteenth century, but by the 1820s the Ottoman armies were unable to put down the Greek War of Independence in southern Greece. The great powers of Europe decided to intervene and assist Greece with its independence. Thus Greece became the first independent country created out of a section of the Ottoman Empire. Russian aspirations for a section of the empire and bases on Russia's southern flank provoked British fears over naval domination of the Mediterranean and control of the land route to the Indian Subcontinent.
