Yadav

The Yadav (or Yadava literally, descended from Yadu), is a caste/community found in India and Nepal As the name of one of the five Aryan clans mentioned in the Rig Veda as Panchjanya, meaning "five people", it is the common name given to the five most ancient vedic kshatriya tribes. People of the Yadav caste generally follow Vaishnav traditions, and share Dharmic religious beliefs. Traditionally Yadavs were classified under the Kshatriya varna in Hinduism and remained in power in India and Nepal until 1200-1300 CE, before the arrival of Muslim invaders. In the 1881 census records of the British Empire it is stated that "the Yadavas, who in their turn are identified with the Gaolis and Ahirs, were the dominant race at that time. 
Subdivisions.
The Yadavs are divided into different subdivisions which have different ritual ranks (Yaduvanshi, Goallavanshi and Nandavanshi). There is nonetheless a strong belief amongst them that all Yadavs belong to.
The Haihayas.
The Haihayas were an ancient confederacy of five "gana"s (clans), who were believed to have descended from a common ancestor, Yadu. These five clans are Vitihotra, Sharyata, Bhoja, Avanti and Tundikera. The five Haihaya clans called themselves the Talajanghas According to the "Puranas", Haihaya was the grandson of Sahasrajit, son of Yadu. Kautilya in his "" mentioned about the Haihayas. In the Puranas, Arjuna Kartavirya conquered Mahishmati from Karkotaka Naga and made it his capital.
Later, the Haihayas were also known by the name of the most dominant clan amongst them — the Vitihotras. According to the "Puranas", Vitihotra was the great-grandson of Arjuna Kartavirya and eldest son of Talajangha. Ripunjaya, the last Vitihotra ruler of Ujjayini was overthrown by his "amatya" (minister) Pulika, who placed his son, Pradyota on the throne. The "Mahagovindasuttanta" of the "Dighanikaya" mentions about an Avanti king Vessabhu (Vishvabhu) and his capital Mahissati (Mahishmati). Probably he was a Vitihotra ruler.
The Shashabindus.
In the Balakanda (70.28) of the Ramayana, the Shashabindus are mentioned along with the Haihayas and the Talajanghas. The Shashabindus or Shashabindavas are believed as the descendants of Shashabindu, a "Chakravartin" (universal ruler) and son of Chitraratha, great-great-grandson of Kroshtu.
The Chedis.
The Chedis or Chaidyas were an ancient Yadava clan, whose territory was conquered by a Kuru king Vasu, who thus obtained his epithet, "Chaidyoparichara" (the overcomer of the Chaidyas) or "Uparichara" (the overcomer). According to the Puranas, the Chedis were descendants of Chidi, son of Kaishika, grandson of Vidarbha, a descendant of Kroshta. And the son of king Chidi was Maharaja DamGoshi(Father of Shishupal in Mahabharata).And then the lineage was called Hindu Ghosis.
The Vidarbhas.
According to the Puranas, the Vidarbhas or Vaidarbhas were descendants of Vidarbha, son of Jyamagha, a descendant of Kroshtu. Most well known Vidarbha king was Bhishmaka, father of Rukmin and Rukmini. In the Matsya Purana and the Vayu Purana, the Vaidarbhas are described as the inhabitants of Deccan ("Dakshinapatha vasinah").
The Satvatas.
According to the Aitareya Brahmana (VIII.14), the Satvatas were a southern people held in subjection by the Bhojas. The Satapatha Brahmana (XIII.5.4.21) mentions that Bharata seized the sacrificial horse of the Satvatas. Panini, in his "Ashtadhyayi" mentions the Satvatas also as being of the "Kshatriya gotra", having a "sangha" (tribal oligarchy) form of government but in the Manusmriti (X.23), the Satvatas are placed in the category of the "Vratya Vaishyas".
According to a tradition, found in the Harivamsa (95.5242-8), Satvata was a descendant of the Yadava king Madhu and Satvata's son Bhima was contemporary with Rama. Bhima recovered the city of Mathura from the Ikshvakus after the death of Rama and his brothers. Andhaka, son of Bhima Satvata was contemporary with Kusha, son of Rama. He succeeded his father to the throne of Mathura.
The Andhakas, the Vrishnis, the Kukuras, the Bhojas and the Surasenas are believed to have descended from Satvata, a descendant of Kroshtu. These clans were also known as the Satvata clans.
The Andhakas.
According to the "Ashtadhyayi" (IV.1.114) of Panini, the Andhakas were of the "Kshatriya gotra", having a "sangha" (tribal oligarchy) form of government In the "Drona Parva" (141.15) of the "Mahabharata", Andhakas were categorized as the "Vratya"s (deviators from orthodoxy). According to the Puranas, the Andhakas were the descendants of Bhajamana, son of Andhaka and grandson of Satvata.
According to the "Mahabharata", the allied army of the Andhakas, the Bhojas, the Kukuras and the Vrishnis in the Kurukshetra War was led by Kritavarma, son of Hridika, an Andhaka. But, in the same text, he was also referred as a Bhoja of Mrittikavati.
The Bhojas.
According to the Aitareya Brahmana (VIII.14), the Bhojas were a southern people, whose princes held the Satvatas in subjection. The Vishnu Purana (IV.13.1-61) mentions the Bhojas as a branch of the Satvatas. According to this text, Bhojas of Mrittikavati were descendants of Mahabhoja, son of Satvata. But, according to a number of other Puranic texts, the Bhojas were descendants of Babhru, grandson of Satvata. In the Adi Parva of the "Mahabharata" (85.3533) and in a passage of the "Matsya Purana" (34.30) the Bhojas are mentioned as the "mleccha"s. But another passage of the "Matsya Purana" (44.69) describes them as pious and the performers of the religious rites.
The Kukuras.
Kautilya in his (XI.1.5), describes the Kukuras as a clan, having "sangha" (tribal oligarchy) form of government, whose leader uses the title of ' ('). According to the Bhagavata Purana, the Kukuras occupied the territory around Dwarka. The Vayu Purana mentions that the Yadava ruler Ugrasena belonged to this clan ("Kukurodbhava"). According to the Puranas, Ahuka, an Kukura, had two sons by a Kashi princess, Ugrasena and Devaka. Ugrasena had nine sons and five daughters, Kamsa being the eldest. Devaka had four sons and seven daughters, Devaki was one of them. Kamsa usurped the throne of Mathura after imprisoning Ugrasena. But later he was killed by Krishna, son of Devaki, who re-installed Ugrasena to the throne.
The Nashik Cave Inscription of Gautami Balashri mentions that her son Gautamiputra Satakarni conquered the Kukuras. The Junagadh Rock Inscription of Rudradaman I includes the Kukuras in the list of the peoples conquered by him.
The Vrishnis.
The Vrishnis are mentioned in a number of Vedic texts, which include the Taittiriya Samhita (III.2.9.3), the Taittiriya Brahmana (III.10.9.15), the Satapatha Brahmana (III.1.1.4) and the Jaiminiya Upanishad Brahmana (I.6.1). The Taittiriya Samhita and the Jaiminiya Upanishad Brahmana mention about a teacher, Gobala belonging to this clan.
Although, Panini, in his "Ashtadhyayi" (IV.1.114) includes the Vrishnis in the list of the clans of the "Kshatriya gotra", having a "sangha" (tribal oligarchy) form of government, but in the "Drona Parva" (141.15) of the "Mahabharata", the Vrishnis, like the Andhakas were categorized as the "Vratya"s (deviators from orthodoxy). In the "Shanti Parva" (81.25) of the "Mahabharata", the Kukuras, the Bhojas, the Andhakas and the Vrishnis are together referred as a "sangha", and Vasudeva Krishna as "Sanghamukhya" (seignor of the "sangha") According to the Puranas, Vrishni was one of the four sons of Satvata. Vrishni had three (or four) sons, Anamitra (or Sumitra), Yudhajit and Devamidhusha. Shura was son of Devamidhusha. His son Vasudeva was father of Balarama and Krishna.
According to the Harivamsa (II.4.37-41), the Vrishnis worshipped goddess Ekanamsha, who, elsewhere in the same text (II.2.12), described as daughter of Nandagopa. The Mora Well Inscription, found from a village near Mathura and dated to the early decades of the Common era records the installation of the images of the five Vrishni "vira"s (heroes) in a stone shrine by a person, named Tosha. These five Vrishni heroes have been identified with Samkarshana, Vasudeva, Pradyumna, Aniruddha and Samba from a passage in the Vayu Purana (97.1-2).
A unique silver coin of the Vrishnis was discovered from Hoshiarpur, Punjab. This coin is presently preserved in the British Museum, London. Later, a number of copper coins, clay seals and sealings issued by the Vrishnis were also discovered from Sunet, near Ludhiana.
The Shaineyas.
The Shaineyas are believed to have descended from Shini, son of Anamitra, son of Vrishni. In the "Mahabharata" and the Puranas, the most notable Shaineya was Yuyudhana, son of Satyaka and grandson of Shini. He was a contemporary of Krishna. According to the Puranas, Asanga and Yugandhara were his son and grandson respectively.
Akrura and the Syamantaka.
A number of Puranas mention Akrura, a Vrishni, as the ruler of Dvaraka. His name is found in the Nirukta (2.2) as the holder of the jewel. In the Puranas, Akrura is mentioned as the son of Shvaphalka, who was great-grandson of Vrishni and Gandini. In the "Mahabharata", the "Bhagavata Purana" and the "Brahma Purana", he was mentioned as the keeper of the Syamantaka, the most well-known jewel of the Yadavas. According to the Puranas Akrura had two sons, Devavant and Upadeva.
The fratricidal war and its aftermath.
According to the "Mausala Parva" (7.185-253) of the "Mahabharata" a few years after the "Kurukshetra War", Andhaka-Vrsni Yadava clans of Dvaraka were destroyed due to a fratricidal war. Both Balarama and Krishna died soon after this war. Later, son of Kritavarma became ruler of Mrittikavati and grandson of Yuyudhana became ruler of the territory near the Sarasvati River. The rest of the surviving Yadavas took refuge in Indraprastha. Vajra, great-grandson of Krishna was installed as their king.
Vajra is mentioned as the great-grandson of Krishna in the Vishnu Purana. According to a section of this text (IV.15.34-42), he was the son of Aniruddha and Subhadra. But according or another section (V.32.6-7), he was the son of Aniruddha and Usha, daughter of Bana and granddaughter of Bali. Bahu (or Pratibahu) was his son and Sucharu was his grandson. Elsewhere in this text (V.38.34), he was mentioned as installed as king in Mathura instead of Indraprastha.
The narrative of the Yadava fratricidal war is also found in two Jataka tales of the Pali Buddhist canon: the "Ghata Jataka" and the "Samkicca Jataka". According to the "Ghata Jataka", Vasudeva, Baladeva and eight other "Andhaka-Venhu" (probably, a corrupt form of "Andhaka-Venhi", Pali equivalent to Sanskrit Andhaka-Vrishni) brothers seized Dvaravati and killed its king Kamsa. Later, these brothers fought amongst themselves and except Vasudeva and Baladeva everybody died. Vasudeva and Baladeva also died soon after. The "Samkicca Jataka" mentions that the "Andhaka-Venhu"s killed each other. Kautilya also in his (I.6.10) mentioned about the destruction of Vrishni clan because of their foolhardiness.
Yadava kinship system.
According to a modern historian, Romila Thapar, the kinship system of the Yadavas shows traces of matrilineal structure, which is found from the mention of their cross-cousin marriages. This is particularly prohibited in the Indo Aryan kinship system. The Vishnu Purana mentions that Krishna married Rukmini, a Vidarbha princess. His son Pradyumna married Kakudvati, daughter of Rukmin, brother of Rukmini. Pradyumna's son Aniruddha married Subhadra, granddaughter of Rukmin.
