Though there is no evidence to suggest that Sharif Hussein bin Ali was inclined to Arab nationalism before 1916. The rise of Turkish nationalism under the Ottoman Empire, culminating in the 1908 Young Turk Revolution, nevertheless displeased the Hashemites and resulted in a rift between them and the Ottoman revolutionaries. During World War I, Hussein initially remained allied with the Ottomans but began secret negotiations with the British on the advice of his son, Abdullah, who had served in the Ottoman parliament up to 1914 and was convinced that it was necessary to separate from the increasingly nationalistic Ottoman administration.
