The Ottoman Empire was manipulated into WWI by the Germans on the side of the Central Powers when the German navy sent one of its naval vessels into the Bosphorus.
While visiting Ephesus my tour guide said that Germany commandeered a naval vessel; fired on a Russian naval ship and was thus entered into the war.
The Ottomans grew economically weak, due to the economic boom of European Industrialization. Their workers lost their jobs due to cheaper products marketted by their European rivals. The Ottoman government, to save their state from this decline wanted educational, cultural and Militarial reforms which would cost so much that their treasury couldn't bare. So they borrowed, from the European Money lenders hence went severely under Debt.
As we can see the pattern repeating itself in a number of occasions during history, Debt can be used as a very powerful tool in political dealing and decision making, proved to be the case. Europeans were going to war amongst each other and wanted as much manpower at their side as possible. So they demanded their pound of flesh from the ottomans by joining the great war, with whichever side they take, promising to help them pay their Debt, if successful.
As the Allied forces sought the help of Russia, an arch enemy of the Ottomans, the Ottomans decided to side Germany.
This may come to a surprise to some, as how can the ottomans go against their European Money lenders, it is suggested that one reads the financing of the Banking elite of both sides of the conflicts of the Nepoleonic wars and their manipulation of the London Stock Exchange, buying up almost all of the shares of the English industries.
Their is another interesting link, regarding the financiers of the war and the possible resultant decision of the Ottomans. The Balfour Declaration of 1917 was issued.
November 2nd, 1917.
Dear Lord Rothschild,
I have much pleasure in conveying to you, on behalf of His Majesty's Government, the following declaration of sympathy with Jewish Zionist aspirations which has been submitted to, and approved by, the Cabinet:
"His Majesty's Government view with favour the establishment in Palestine of a national home for the Jewish people, and will use their best endeavours to facilitate the achievement of this object, it being clearly understood that nothing shall be done which may prejudice the civil and religious rights of existing non-Jewish communities in Palestine, or the rights and political status enjoyed by Jews in any other country".
I should be grateful if you would bring this declaration to the knowledge of the Zionist Federation.
Arthur James Balfour
It wanted to increase its territory and help its allies.
