Muhammad Ali acquiesced

At this point, the European powers again intervened. On 15 July 1840, the British government, which had negotiated with Austria, Prussia, and Russia to sign the Convention of London, offered Muhammad Ali hereditary rule of Egypt as part of the Ottoman Empire if he withdrew from the Syrian hinterland and the coastal regions of Mount Lebanon. Muhammad Ali hesitated, believing he had support from France. His hesitation proved costly. France eventually backed down as King Louis-Philippe did not want his country to find itself involved and isolated in a war against the other powers, especially at a time when he also had to deal with the Rhine crisis. British naval forces were ordered to sail to Syria and Alexandria. In the face of such displays of European military might, Muhammad Ali acquiesced. Muhammad Ali finally had to accept the convention on 27 November 1840.
