The Caspian Sea.
The Middle East is not only bordered by the Caspian Sea, but the Mediterranean, Black, Red, Aegean and Arabian seas, and the Sea of Marmara.
There are several definitions of the Middle East region. The most common one follows the borders of Middle Eastern countries, like the edges of Egypt, Turkey, and Iran. This edge also runs through the Mediterranean Sea, the Red Sea, the Gulf of Aden, the Arabian Sea, and the Caspian Sea.

Pretty much all of the conflicts in the Middle East changed borders except the Iran-Iraq War and the Arab-Israeli War of 1973. The conflict that altered the borders of the Middle East most strongly in the 20th century was World War I and the creation of British and French Mandates.
The British and French drew most of the borders in the Middle East in the Sykes-Picot Agreement. Turkey and Israel also helped to draw the borders in the Middle East after successful military campaigns (which neither started).
