Sindhi Language Bill, 1972 was introduced by the Chief Minister Mumtaz Bhutto on July 3, 1972 in the Sindh Assembly, Pakistan. The 1972 Language violence in Sindh occurred starting on July 7, 1972 when the Sindh Assembly passed the The Sind Teaching, Promotion and Use of Sindhi Language Bill, 1972 which established Sindhi language as the sole official language of the province resulting in language violence in Sindh. Due to the clashes, Prime Minister Zulfikar Ali Bhutto compromised and announced that Urdu and Sindhi will both be official languages of Sindh. The making of Sindhi as an equal language to Urdu for official purposes frustrated the Urdu-speaking people as they did not speak the Sindhi language.
It provided inter alia that:
Subject to the provisions of the Constitution, Government may make arrangements for progressive use of Sindhi language in offices and departments of Government including Courts and Assembly.
