"It has been a long standing demand to rename Hyderabad-Karnataka as Kalyana Karnataka. With God's grace at the time when I'm the Chief Minister of the state, I'm declaring Hyderabad-Karnataka as Kalyana Karnataka.
There is a festive atmosphere in the six districts of the region," Yediyurappa told reporters at Kalaburagi.
The Chief Minister said a separate secretariat would be set up for the development of Kalyana Karnataka, through which funds would be released for developmental work All other formalities relating to the renaming would follow in consultation with the centre, he said.
Assuring more funds for the all round development of the Kalyana Karnataka region, Yediyurappa said there may be financial issues this time due to floods in several parts of the state, but more funds would be allocated for development in the next budget.
The renaming announcement was made by the Chief Minister ahead of hosting of the national flag in Kalaburagi on the occasion of commemoration of "Hyderabad-Karnataka Liberation Day" on Tuesday.
The region was under the Nizams of Hyderabad even after independence as the last Nizam, Mir Osman Ali Khan Bahadur, refused to annex his kingdom to the Indian Union.
On September 17, 1948 he merged with the Union of India after Police Action under the leadership of India's first Home Minister Sardar Vallabhbhai Patel, which forced the Nizam and his army to surrender.
The region, comprising Bidar, Ballari, Kalaburagi, Koppal, Raichur and Yadgir, enjoys special status under the Constitution (Article 371J) owing to its backwardness.
The name Kalyana RPT Kalyana comes from the Kingdom of Kalyana, which was the epicenter of Sharana movement and Vachana Sahitaya preached and followed by several social reformers, including Basvanna.
