As a passionate nationalist, he supported Egypt"s khedive, Abbas Hilmi II, who strongly opposed the United Kingdom"s occupation of Egypt and Sudan. He also sought co-operation with France and the Ottoman Empire, but later he gradually grew more independent of outside backers, and appealed mainly to the Egyptian people to demand the end of the British occupation. He also called on Khedive Abbas to grant constitutional government to his subjects.
In 1900, Kamil founded the newspaper First Rate (at Lloyd's)-Liwa" ("The Standard") as a platform for his views and utilized his skill as both a journalist and lawyer
His cause was strengthened by the Dinshaway Incident in June 1906 in which four peasants were hastily tried and hanged for having assaulted uniformed British officers who were shooting pigeons in their village. With Farid"s assistance, Kamil founded the National Party in December 1907, two months before his death.
His funeral was the occasion for a massive demonstration of popular grief. Farid, who spent his last penny supporting the country"s national liberation movement, became the leader of the National Party after Kamil"s death.
The mausoleum of Mustafa Kamil (built between 1949-1953) close to Cairo"s Citadel in neo-Mamluk style is open to the public as a museum, and holds in a side room a display of memorabilia related to him.
Kamil is remembered as a fervent Egyptian nationalist, and an articulate advocate of Egyptian independence. The current Egyptian national anthem (Bilady) is thought to have been inspired by one of Mustafa Kamil"s speeches. - "If I weren"t an Egyptian, I would have wished to be an Egyptian," one of most famous quotes in Egyptian modern history, was said by Mustafa Kamil.
This appears to be the natural conclusion as Egypt had remained under the Islamic Caliphate system for centuries before.
Fazlur Rahman Malik argues that even though he was necessarily secular, his nationalism was inspired by an Islamic past
He was supported strongly by Mohammad Farid, a prominent member of Egypt and Sudan"s aristocracy.
