Its name is not found in the ancient or medieval history of our lands. There have once been dense, impenetrable and uninhabitable forests. To the west, in the valley of the White River, there was the old Chounigrad, from which there is no trace. For the resistance, the Turks took off the city, but its proud and stubborn defenders remained unruly. A group of 40 heroes, headed by the Kalifer Voivode, had long wandered around the area, defending their fellows, and horror among the Ottomans. The Turks were powerless to handle, so the Sultan allowed the voivode to settle with his boys in the woods, giving them privileges to a Dervender village. The Haiduts stole Sopot girls, who were famous for their beautiful ones, and so Kalofer originated..
 
It is no coincidence that the history of the town during the long foreign domination is full of names of famous haramies, haidoutes and rebels, beginning with Kalifer voivoda, Grandpa Mlichko, Chono Chorbadji, Dobri Voyvoda, Galab voivoda and finished with the genius poet and revolutionary Hristo Botev. Twice the town was burned down by the Kurdjali - in 1799 and 1804, but it quickly recovered and froze. In the first half of the 19th century, Kalofer, as well as all of our sub-Balkan cities, has reached its peak. Travelers noted that there were more than 1,000 guillotine bugs, many mopples and paintbrushes. Kalofer's craftsmen and merchants traded with Constantinople, Vienna, Odessa, Braila. It was not accidental that they called it "Altan Kalofer" (Golden Kalofer). In 1845 a new big school was built, and in 1871 a school for girls. Billy founded various educational societies.
 
The children of Kalofer are a number of prominent writers and public figures from the Revival period - Ekzarh Iosif I, Dimitar Mutev, Elena Muteva (the first Bulgarian poet), Hristo Tapchileshtov, Ivan Shopov (folklorist and first Bulgarian bibliographer) and others. Many Kalofers took part in the cheti of Panayot Hitov, Philip Totyu, Hadji Dimitar and Stefan Karadja, Bacho Kiro. Towards the end of the Ottoman rule, in the vicinity of Kalofer, there were 15 haidouk cheti. Over 500 Khalifa have participated in haidouk cheti and bands. During the Liberation War and Kalofer had the fate of Karlovo and Sopot - burned and plundered by the bashi-boss. There is almost nothing left of Kalofer's pre-liberation.
