Titus, Vespasian's successor, quickly proved his merit, although his short reign was marked by disaster, including the eruption of Mount Vesuvius in Pompeii. He held the opening ceremonies in the still unfinished Colosseum but died in 81.

Napoleon ignored repeated advice against an invasion of the Russian heartland and prepared for an offensive campaign; on 24 June 1812 the invasion commenced.

The Porte felt strong enough to renew the struggle, and war broke out once more. Ibrahim won his last victory for his father at Nezib on June 24, 1839.

The Battle of Nezib was fought on 24 June 1839 between Egypt and the Ottoman Empire. The Egyptians were led by Ibrahim Pasha, while the Ottomans were led by Hafiz Osman Pasha.

When Mahmud II ordered his forces to advance on the Syrian frontier, Ibrahim attacked and destroyed them at the Battle of Nezib (24 June 1839) near Urfa. In an echo of the Battle of Konya, Constantinople was again left vulnerable to Ali's forces. A further blow to the Ottomans was the defection of their fleet to Muhammad Ali. Mahmud II died almost immediately after the battle took place and was succeeded by sixteen-year-old Abdülmecid. At this point, Ali and Ibrahim began to argue about which course to follow; Ibrahim favored conquering the Ottoman capital and demanding the imperial seat while Muhammad Ali was inclined simply to demand numerous concessions of territory and political autonomy for himself and his family.
