Here's a short story:

Odisha (; formerly Orissa, ) is one of the 29 states of India, located in eastern India. It is surrounded by the states of West Bengal to the north-east, Jharkhand to the north, Chhattisgarh to the west and north-west, and Andhra Pradesh to the south. Odisha has of coastline along the Bay of Bengal on its east, from Balasore to Ganjam. It is the 9th largest state by area, and the 11th largest by population. It is also the 3rd most populous state of India in terms of tribal population. 

Odia (formerly known as "Oriya") is the official and most widely spoken language, spoken by 33.2 million according to the 2001 Census. 

The ancient kingdom of Kalinga, which was invaded by the Mauryan emperor Ashoka in 261 BCE resulting in the Kalinga War, coincides with the borders of modern-day Odisha. The modern state of Orissa was established on 1 April 1936, as a province in British India, and consisted predominantly of Odia-speaking regions. April 1 is celebrated as Odisha Day. The region is also known as Utkala and is mentioned in India's national anthem, "Jana Gana Mana". Cuttack was made the capital of the region by Anantavarman Chodaganga in c. 1135, after which the city was used as the capital by many rulers, through the British era until 1948. Thereafter, Bhubaneswar became the capital of Odisha. (End of story)
