The English-language Hürriyet Daily News has an outstanding roundup of recent events in the Arab world today, to which I call to your attention because the perspective they provide is one that you might miss in similar roundups in the American press. Particularly look at the column on "relations with Turkey." Some highlights:
Libya: Ruled by Ottomans from 1551 to 1912 as three separate districts, which were consolidated by Italy. Until the late 1960s, Turkey trained Libyan officers. Former PM Abdesselam Jaloul is a graduate of the Turkish Military Academy.
Bahrain: Bahrain was administered by the Ottoman Empire’s Najd Governor of the Arab peninsula during the 18th century.
Yemen: The first Ottoman rule began in the 16th century and lasted through the 17th century. Its second rule was between 1848 and 1918. Nearly 300,000 Ottoman soldiers were killed during war in Yemeni deserts, which became the host of a gigantic Turkish cemetery.
Oman: Never became a province of the Ottoman Empire, but did pass through a short period in the 16th century as a political dependent.
Algeria: Algeria was under Ottoman rule from 1514 until the French occupied the country in 1830.
Tunisia: Occupied in 1574 by the great Barbaros Hayrettin Paşa, an admiral in the Ottoman Navy who dominated the Mediterranean for decades. The country was known as the “Regency of Tunis” under Ottoman rule until 1881.
Iran: These two neighboring nations have had close relations throughout history, starting from when the Great Seljuk Empire first entered Anatolia from Persia in the 10th century. (My note: This is a considerable simplification.)
Sudan: Ottomans ruled the country in the 19th century.
Jordan: Ruled by the Ottomans from 1516-1917 under the Damascus Governorship. Home to a cemetery for Turkish soldiers.
The maps show the expansion and decline of the Ottoman Empire. The summaries, I think, suggest the extent to which nothing in the contemporary Middle East may be understood without a grasp of Ottoman history. That's one big footprint the Turks left.
