The Language Movement gained momentum, and after a long struggle, Bengali gained official status in Pakistan (with Urdu) in 1956. To commemorate the dead, the Shaheed Minar was designed and built by Bangladeshi sculptors Hamidur Rahman in collaboration with Novera Ahmed. Construction was delayed by martial law, but the monument was finally completed in 1963, and stood until the Bangladesh Liberation War in 1971, when it was demolished completely during Operation Searchlight. After Bangladesh gained independence later that year, it was rebuilt. It was expanded in 1983.
