Egyptian colonizing nationalism crystallized in the 1870s and peaked around 1899

Evidence

This dualistic nationalism did not begin in 1894 with the slavery trial, nor did it reach its culmination with the untimely death of Kämil in 1908. It was not a static movement but one that changed with people and events in Egyptian history. The outlook of the colonized colonizer began to take shape in the last decade of Muhammad `Alï’s reign and emerged full-blown by the 1870s. Nationalists developed these themes throughout the rest of the nineteenth century but especially from 1898 to 1899, the period of the British reconquest of the Sudan. By 1919 there was a well-established slogan that called for “the unity of the Nile Valley.” — Eve M. Troutt Powell, A Different Shade of Colonialism_…, 62
