Mohajirs had never liked the idea of identifying themselves with Sindhi population on the basis of ethnicity or nationality and were always hostile of "Sindhi nationalism" instead of "ethnic nationalism." But Ethno-nationalist politicians convinced them that circumstances needed them to seek their identity on ethnic lines. The Muhajir sense of isolation came into being through a series of events. The three most important being the 1964 presidential elections, the 1972 language riots, and the post-1985 ethnic clashes between Muhajirs and non-Muhajirs in Karachi. "During the December 1964 presidential elections, the Muhajir population of Karachi experienced a wrath of a Pathan backlash when Gohar Ayub Khan, son of President Ayub Khan, launched a series of attacks on Muhajir communities because of their support for Fatimah Jinnah, the sister of Mohammad Ali Jinnah, against Ayub Khan." Though Gohar Ayub's intentions were to target those who opposed his father, ethno-nationalists portrayed the move as specifically targeting Muhajirs At this time Ayub Khan moved the federal capital from Karachi to Islamabad, causing further anger amongst the elite of the Muhajir community, especially the bureaucracy.
