According to the historical context, what did the British government hope to accomplish securing the support of Arab leaders? What did Sharif Hussein want in return?

Great Britain encouraged Arab revolts against the Ottoman Empire as a way to weaken it during the First World War. It promised them independent kingdoms and was also interested in a trade relationship after the war. Sharif Hussein, who was the Emir of Mecca, was an Ottoman ally.

In his exchanges with the British, he made it clear that he expected to be appointed the ruler of a new, large Arab state after the war.
