International Mother Language Day

The United Nations' (UN) International Mother Language Day annually celebrates language diversity and variety worldwide on February 21. It also remembers events such as the killing of four students on February 21, 1952, because they campaigned to officially use their mother language, Bengali, in Bangladesh.
International Mother Language Day is also known as Shohid Dibôsh, or Shaheed Day.

At the partition of India in 1947, the Bengal province was divided according to the predominant religions of the inhabitants. The western part became part of India and the eastern part became a province of Pakistan known as East Bengal and later East Pakistan. However, there was economic, cultural and lingual friction between East and West Pakistan.

These tensions were apparent in 1948 when Pakistan's government declared that Urdu was the sole national language. This sparked protests amongst the Bengali-speaking majority in East Pakistan. The government outlawed the protests but on February 21, 1952, students at the University of Dhaka and other activists organized a protest. Later that day, the police opened fire at the demonstrators and killed four students. These students' deaths in fighting for the right to use their mother language are now remembered on International Mother Language Day.

The unrest continued as Bengali speakers campaigned for the right to use their mother language. Bengali became an official language in Pakistan on February 29, 1956. Following the Bangladesh Liberation War in 1971, Bangladesh became an independent country with Bengali as its official language.

On November 17, 1999, UNESCO proclaimed February 21 to be International Mother Language Day and it was first observed on February 21, 2000. Each year the celebrations around International Mother Language Day concentrate on a particular theme.
