Aizawl: Mizoram on Tuesday celebrated 32nd statehood day, the anniversary of its being upgraded to full-fledged statehood from Union Territory status, after signing the historic Mizo Accord in 1986.

Though no official functions were organised by the state government, all the government offices and educational institutions remained closed as the state government declared a public holiday to mark the occasion.

Prime Minister Narendra Modi greeted the people of Mizoram on the occasion in a tweet. He shared an image with the message, "On the occasion of their statehood day I convey my greetings to the wonderful people of Mizoram."

"My best wishes for the development journey of Mizoram," he tweeted.

Former Prime Minister Rajiv Gandhi marked the first state statehood day on February 20, 1987, at Lammual (AR ground) here after his government successfully signed the Mizo Accord with the erstwhile underground Mizo National Front (MNF) on June 30, 1986, ending the 20-year insurgency in the hilly northeastern state.

After this, the bill to make Mizoram a full-fledged state was introduced in the Lok Sabha on August 7 the same year.

The bill was passed by the Lok Sabha with 308 votes out of 310 and the Rajya Sabha passed the bill with 160 out of 171 members voting in favour of it.

Mizoram became the 23rd state of the Indian Union after the President gave his assent on August 14, 1986.

The then Lieutenant Governor of Mizoram Hiteswar Saikia was sworn in as the first governor by the Chief Justice of Gauhati High Court at the Raj Niwas in Aizawl.

The late legendary MNF leader Laldenga, who was chosen as the chief minister in the interim MNF-Congress coalition government, became the first chief minister of the state.

About 95 per cent of the current population is of diverse tribal origins. According to the 2011 general census, the total population of the state was 10,91,014, of which about 87 per cent are Christians. It is the second least populous state in the country.
