Which development lead to World War I spreading to the middle east

The Ottoman Empire called for a jihad (holy war) against its enemies.

Explanation:

The Ottoman Empire had great influence in the Middle East before the outbreak of World War I. Much of the area was under Ottoman rule. The Ottoman Empire welcomed the beginning of the war on the side of Germany and Austria-Hungary. The Ottomans called for a holy war against the enemy. The English knew that the Ottomans could be a powerful ally to Germany. That is why they started deploying their troops in Basra, an area not far from the Euphrates and Tigris' mouth. The Ottomans tried to thwart British actions with attacks but without success. The British tried to transfer the fight to the sea, but that attempt was unsuccessful. When we talk about the front in the Middle East, it is necessary to mention the Gallipoli campaign and the Ottoman troops' great success.

The Indians were at war with British troops. They were concerned that the Ottoman call for holy war could have a strong repercussion in Pakistan and could threaten the entire country. As the war progressed, the Ottoman Empire fell more and more into the abyss. The fight with the British was in vain. Even with Germany's help, the Ottoman Empire could not have enough resources to continue the struggle. The British, on the other hand, had enormous capacities. The end of the war meant the elimination of Ottoman influence from the Middle East. It also meant the creation of some new states that gained independence. There was also a strengthening of British influence in that part of the world.
