India celebrates 26 January as its Republic day, Poorna Swaraj Day and making Hindi as its official language. That means 3 in 1 celebrations.
But there was a time when this day was celebrated as Independence day.
Way back in 1930, Indian young leaders decided to attain complete independence or ‘Poorna Swaraj’. A resolution was passed, fixing the last Sunday of January, 1930, to be celebrated as our Independence Day, which incidentally fell on the 26th. On that day, Jawahar Lal Nehru hoisted the tricolour on the banks of Ravi in Lahore.
Although we actually got independence on 15th August, 1947. Later, it marked our Independence Day.
Our Constituent Assembly was formed in 1946 which made our Constitution under the chairmanship of Dr. B R Ambedkar. The constitution was ready by the 26th of November, 1949. It was then that the leaders, in honour of the first Independence Day celebrations of 26th January, 1930, decided to wait for 2 more months to officially enforce it. Hence, Republic day is celebrated in this honour every year.
The Indian constitution, on 26 January 1950, declared Hindi in Devanagari script to be the official language of the union. Soon after this declaration non-Hindi speaking states were given a 15-year grace period, till 1965, to make the complete switch over to Hindi. It was believed that Hindi would become the sole working language of the Central Government and the State governments were expected to communicate with the Centre only in Hindi.
Note : Hindi is till date our official language and not national language.
