What caused the conflict in the Middle East?

The Middle East is a transcontinental region in Afro-Eurasia which generally includes Western Asia, all of Egypt, and Turkey. The term has come into wider usage as a replacement of the term Near East beginning in the early 20th century. The broader concept of the "Greater Middle East" also includes the Maghreb, Sudan, Djibouti, Somalia, the Comoros, Afghanistan, Pakistan, and sometimes Transcaucasia and Central Asia into the region. The term "Middle East" has led to some confusion over its changing definitions.
