Lohar (caste) in the context of Ramgarhia

The Maratha caste is composed of 96 clans, originally formed in the earlier centuries from the amalgamation of families from the peasant (Kunbi), shepherd (Dhangar), blacksmith (Lohar), pastoral (Gavli), carpenter (Sutar), Bhandari, Thakar and Koli castes in Maharashtra. Many of them took to military service in the 16th century for the Deccan sultanates or the Mughals. Later in the 17th and 18th centuries, they served in the armies of the Maratha Kingdom, founded by Shivaji, a Maratha Kunbi by caste. Many Marathas were granted hereditary fiefs by the Sultanates, and Mughals for their service.

According to the Maharashtrian historian B. R. Sunthankar, and scholars such as Rajendra Vora, the "Marathas" are a "middle-peasantry" caste which formed the bulk of the Maharashtrian society together with the other Kunbi peasant caste. Vora adds that the Marathas account for around 30 per cent of the total population of the state and dominate the power structure in Maharashtra because of their numerical strength, especially in the rural society.

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.

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 (Romani: natsiya) 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 (Romani: vitsa) 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.
