The National Students Federation Pakistan (NSF) is a left-wing students federation in Pakistan. In the late 1960s, NSF adopted the political line of Marxism–Leninism and Mao Zedong Thought. Its predecessor, the DSF (Democratic Students Federation), had links to the Communist Party of Pakistan. It had power base among progressive students from Dow Medical and DJ Science Colleges. It dominated student politics in Karachi, the then Federal Capital of the country. In a convention at the national level of students, held in Khaliqdina Hall, Karachi(1953), the DSF renamed itself to NSF (National Student Federation in the late 1960s), laying claim to being a national movement and hoping to spread the Student Revolution to the whole country. Demonstrations and strikes had already paralysed the federal capital for several days. The government apparently gave in by sacrificing the federal minister of education, Mr Fazlur Rahman, hailing from the eastern wing. He was sacked from his post. It was not much of a victory for the students. APSO was banned and the leaders were thrown in Karachi Central Jail. NSF (The National Students Federation) a small nationalist and right-wing group which had been propped up by the help of Karachi University Vice Chancellor to counter DSF's activities, was invaded practically overnight by the now banned DSF party members, who were still outside. The ex-DSFites had enough muscle and organisational skills to take over the control of NSF in 1956, thus its new "left" leaning profile emerged. Due to its links with communist movement, DSF was infested with the presence of double agents/informers from the secret service. First split NSF saw its first major split in 1965, between the pro-China and pro-Moscow factions, better known as the NSF-Miraj Group and the NSF-Kazmi Group. While the NSF-Mairaj group supported the PPP, the NSF Kazmi group was the student arm of the National Awami Party (NAP), which today is the ANP. Because this particular faction hold most backward views within the progressive movement they soon loose the ground. Mr Ameer Haider Kazmi took position in PPP and his faction was liquidated. NSF remain active in many Pakistani universities and colleges and won the elections of Students Unions. It played a major role in the popular student and labour uprising against the pro-US dictatorship of Field Marshal Ayub Khan in 1967 and 1968. NSF activists were among the first major supporters of future Pakistani Prime Minister Zulfiqar Ali
