1972 Language violence in Sindh
1972 Language violence in Sindh occurred starting on 7 July, 1972 when the Sindh Assembly passed 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, Pakistan. 
The proclamation of Sindhi as the official language of Sindh resulted in the Daily Jang, a Urdu from Karachi, publishing a full-page story on their front page surrounded by a banner with the statement "Urdu ka janaza hai zara dhoom se nikle" (It is the funeral of Urdu thus should be a flaunting one) by Rais Amrohvi. 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.
In 1988 thousands of Sindhi killed by Mahajir qaomi Movement (MQM) Led by Mr Altaf Hussain.
In 2018 Chief of the Army staff start operation against this organization and arrested terrorists.
