In 1948, there was rising agitation in East Bengal against the omission of Bengali script from coins, stamps and government exams. Thousands of students, mainly from the University of Dhaka, protested in Dhaka and clashed with security forces. Prominent student leaders including Shamsul Huq, Khaleque Nawaz khan, Shawkat Ali, Kazi Golam Mahboob, Oli Ahad, and Abdul Wahed were arrested and the police were accused of repression while charging protesters. In March, senior Bengali political leaders were attacked whilst leading protests demanding that Bengali be declared an official language in Pakistan. The leaders included A. K. Fazlul Huq, the former Prime Minister of undivided Bengal. Amidst the rising discontent in East Bengal, Jinnah visited Dhaka and announced that Urdu would be sole state language of Pakistan given its significance to Islamic nationalism in South Asia. The announcement caused an emotional uproar in East Bengal, where the native Bengali population resented Jinnah for his attempts to impose a language they hardly understood on the basis of upholding unity. The resentment was further fuelled by rising discrimination against Bengalis in government, industry, bureaucracy and the armed forces and the dominance of the Muslim League. The Bengalis argued that they constituted the ethnic majority of Pakistan's population and Urdu was unknown to the majority in East Bengal. Moreover, the rich literary heritage of the Bengali language and the deep rooted secular culture of Bengali society led to a strong sense of linguistic and cultural nationalism amongst the people of East Bengal. The only significant language in Pakistan not written in the Persian-Arabic script was Bengali. Against this backdrop, Bengali nationalism began to take root within the Muslim League and the party's Bengali members began to take a stand for recognition.
