Another storm speedily gathered upon the Ottoman Empire excited by Mehmet Ali, the pasha of Egypt. He was born in Cavalla, the Ancient Neapolis, in Roumelia and he was commonly called as Mehmet Ali Pasha of Cavalla. This powerful vassal had held the government of that country through the entire reign, and had hitherto served the Sultan Mahmoud faithfully, rendering him important assistance during the contest with Greeks. His career was remarkable for its almost uniform success, till ambition brought him into collision with his liege lord and the European powers.

French invasion of Egypt led him to the scene of his future distinction. He volunteered to defend Egypt from Napoleon’s invasion and his successful defend led him to be the governor Pasha of the region. He abolished the Kolemen State in Egypt, he established a very powerful army and a navy by the assistance of French he reformed the Egyptian agriculture by opening water channels.

The Pasha, assisted Sultan Mahmoud in the revolt of Morea and he wanted to be the Governor of Morea and Kyrete. Although he repressed the revolt of Morea, he did not send his army during the Ottoman-Russian War. He requested to be the governor of Syria and due to the Sultan’s rejection of his request, he invaded Syria. He passed the Taurus Mountains and defeated the Ottoman Army in Konya and Adana (Mediterranean Region)

After these victories, it was nearly impossible to stop him through Istanbul. Sultan Mahmoud, asked for Russian co-operation, but, Britain and France with the panic of the possibility of an Ottoman-Russian agreement, convinced Mehmet Ali Pasha to sign an agreement with the Ottoman Government. This agreement was signed in Kutahya and Pasha was appointed to be the Governor of Morea, Kyrete and Syria. Beside, his son Ibrahim Pasha became the governor of Cidde and Adana.

A strong ruler in Egypt was out of Britain’s benefits as Mehmet Ali Pasha was hindering British Trade in the region. The British had decided to dismiss the Pasha and provoke Sultan Mahmoud against him. The Ottoman navy had attacted Pasha’s forces but they were defeated and the Ottoman Admiral (Kaptan-ı Derya) gave the navy to the Pasha (1839). By this domestic war, the Ottoman Navy was completely lost, the army was seriously injured. During these events, Sultan Mahmoud had passed away and his son Abdulmejid was crowned.
