Golla (caste)

The Gollas are a Telugu-speaking pastoral community, who are populated in the states of Andhra Pradesh, Telangana, Karnataka and Tamil Nadu. They represent 13.4% of the total population of Andhra Pradesh state. Gollas are traditionally cowherds, but they engage in both sheep/goat and cattle pastoralism, in that they either herd exclusively sheep, or a mixed herd of sheep and goats, or cattle. 
Etymology.
The Gollas are called Gawalis. One etymology for their name comes from the Sanskrit "Gopala" which in North India passed through Prakrit "Goala", other variants also occur in South India, in such forms as Gollavaru, Godlavaru etc. There are many synonyms by which they are referred to within their community, namely, Kadugolla, Oorugolla, Adivigolla, Handigolla and Gopala. Others refer to them only as Golla or Gollaru.
The Gollas also call themselves Yadava. In the early 1920s, castes such as Ahir, Gavli, Golla, Gopa and Goala, which were traditionally engaged in cattle-related occupations, started referring to themselves as Yadav/Yadava. They claimed that they are related to the Abhiras and Yadavas of the Puranas, which were held to be synonymous and associated with Lord Krishna, a cowherd.
Sub-castes.
The community, due to its size, has a great number of sub-castes namely: Yerra, Mushti, Karine, Pakinati, Puja, Modateetta, Nallasadana, Gujarathi, Gampa, Peyya, Veyya and Sidda. In the early 20th century, the Yerra Gollas dominated the Golla community in Hyderabad state. A small population of the community lived in Karnataka who spoke Kannada. Widow Remarriage is allowed in certain subdivisions of the caste.
Assimilation into Yadav community.
In 1923, leaders from North Indian Ahir and Maharashtraian Gavli community formed All India Yadav Mahasabha (AIYM) to promote Yadava identity amongst regional castes whose occupation was associated with cattle, i.e, cowherds, herdsmen, milksellers. They claimed that they are related to the Yadu dynasty of the Puranas, hence the term "Yadav", through the Abhira tribe. Lord Krishna, a cowherd, was the hero-god of Abhiras. The AIYM insisted that all these regional castes known by different names, call themselves Yadav/Yadava and that each person have Yadav as his last name, and this was enthusiastically followed by various communities who were traditionally involved in cattle related occupations. The Gollas of Hyderabad state, under the leadership of their regional association, the Hyderabad Rashtra Yadava Mahajana Samajam, requested to the Census Commissioner for a change in their caste names Golla, Gawli, Gollawar and Ahir to Yadava. Similarly, in 1930, the government of Madras state directed the adoption of the term "Yadava", in place of Golla, Idaiyan, Gopa, Gopi or Gowla, in all official documents. This was in response to an appeal made by the Yadukula Maha Sangham of east Godavari District.
Religion.
Gollas are both Vaishnavites and Saivites. They put on a vertical yellow or red streak on their forehead, indicating Vaishnavism, and worship a deity Mallanna, who is a form of Shiva. The Yerra or Kilari Gollas regard themselves superior to other Gollas and put on a sacred thread during marriages.
Social status.
The social status of Gollas was fairly high and they were treated equally with the agricultural peasants like Kapu, Kamma, and Balija castes and also they were allowed to mix freely among them. 
Some sources suggest that they might have immigrated from North India.
The Gollas are classified as Other Backward Class in the Indian system of reservation.
