Kalderash

The Kalderash are a subgroup of the Romani people. They were traditionally coppersmiths and metal workers and speak a number of Romani dialects grouped together under the term Kalderash Romani, a sub-group of Vlax Romani. thumb|The three main confederations of Romani people in Europe, Kalderash (yellow), Sinti/Manush (blue), Gitanos (red), as well as the Dom people of the Middle East (green)

The Kalderash of the Balkans and Central Europe, in addition to the Gitanos and Manouche/Sinti, are seen as one of the three main confederations () of Romani people in Europe by certain ethnographers. The Kalderash are recognized as the most numerous confederation of the three. Each main confederation is further split up into two or more subgroups () based on a combination of factors such as occupation, ancestry, or territorial origin. Although originally referring to a specific vitsa of traditional coppersmiths, the name Kalderash is now applied to several Vlax-Speaking Roma groups. Because of this, significant differences in speech and culture can be seen in Western and Eastern Kalderash populations; as evidenced in the differences between the eastern Kalderash of Russia and the western Kalderash of Serbia. Certain scholars have suggested a connection between occupational Romani subgroups and the Caste System of India; with the Kalderash being described as an ancestral stock of the Lohar caste.
