The Sarvaiyas come from a branch of the Chudasamas, who are themselves a branch of the Samma Rajputs. They consider themselves to be brethren and such do not intermarry. As with the Chudasamas, they worship Khodiyar as their Kuldevi.
Their name derives from the estate of Sarva, which they once ruled. Among other estates that they ruled were Amreli, Hathasnsi, Jesar, Vasavad, Santhli, Chital, Kundla, Gohilwad, Chhatrasa, Chiroda, Chok, Pan, Ranigam, and other estates in Kathiawar.
Sarvaiyas, like the Chudasamas, lost most of their kingdoms when Muslims invaded Gujarat. In 1476 Sultan Mahmud Begada also attacked Sarvaiya kingdoms of Amreli, Kundla and others in which they were defeated. When Mahmud Begada, attacked Amreli, after taking over Junagadh from Chudasama, the Sarvaiya rulers of Amreli, two brothers Jaso (Jesaji) and Vejo (Vejaji) became outlaws, in order to re conquer Amreli. Many bardic verses are said of their exploits. After remaining in outlawry for twelve years, they gave up Amreli and settled in Hathasni. Later, the brothers divided the new estate between them, Jesoji receiving Hathasni and Vejoji estate of Jesar.
The fort of Vejalkotha also known as Vejalkot is named after its founder Sarvaiya Vejo (Vejoji), which is located in Girnar on eastern bank of Raval river and is now an archeological site of interest.
They were thus reduced to small estate and village chiefs after they lost Amreli and their old glory. However, till the time of independence, the princely state of Jesar, Hathsani and nearby estates were ruled by Sarvaiya Rajputs. The Jesar along with other Princely States was merged into Union of India to form the United State of Kathiawar.
- Ra Navghan, the ruler of Junagadh is a common ancestor of Sarvaiya, Raijada and Chudasama Rajput clans. Ra' Navghan was the ruler of Wamansthali of Junagadh in 1025–1044 CE and leader against Solanki Rajput king of Gujarat. He was the son of Ra' Dayaji and had escaped capture by King Solanki with his mother, then was raised by an Ahir family in strict secrecy. The Ahirs, former supporters of the Chudasama rulers, sacrificed their own son in place of young Ra' Navghan. In adulthood, Ra Navghan led a group of supporters to recapture Wamansthali from the Solanki ruler.
