Phoolasar was granted as a Sasan Jagir to Chaturbhuj Singh Siddhap, most likely hailing from the Patodi ka Bas jagir of the Siddhap Rajpurohits by the Pokarna Rathores of Pokhran, a prominent noble branch of the Rathore dynasty. This grant was made as a token of gratitude for Chaturbhuj Singh's courageous and diplomatic intervention in freeing a royal member of the Pokarna Rathore family who had been imprisoned in Jaisalmer jail by the Maharawal of Jaisalmer.

Chaturbhuj Singh paid a large sum of gold mohars (coins) to secure their release, showcasing his bravery, loyalty, and influence. In return, the Pokarna Rathores granted him the fertile and strategically located estate of Phoolasar.

This grant was approved by Rao Lunkaran Pokarna with the consensus of a Sarv Samiti of 42 Rathore Khedas, making Phoolasar the 43rd Kheda—the only Rajpurohit Kheda among 42 Rathore ones. Earlier, whenever any major decision took place in Pokaran, Phoolasar’s presence was mandatory.

Phoolasar is located on the tri-junction of the boundaries of:

• Dantal

• Gadhi Champawatan

• Falsund

This positioning made it not only a vital outpost but also a culturally rich jagir that remained vigilant in defending Rajpurohit honor and Hindu dharma.

Phoolasar is home to several heroic memorials and temples dedicated to warriors (Jhujhars) and satis, symbolizing centuries of courage and sacrifice by the Siddhap clan:

• Kuldevi Temple of Hinglaj Mata – the chief goddess of the Siddhap clan

• Thakurji Mandir (Shri Krishna Temple) – main deity worshipped in the jagir

• Shiv Ji Temple

• Majisa Temple

• Bheruji Temple

• Var Devi (Isht Devi)  – Baan Mata Ji
  
• RamdevJi Temple

Additionally, there are several shrines for family deities and local protectors. Phoolasar also has 1 big and 2 small ponds (talabs) that support water storage and rituals.

चौहाना सूं राड़ छती, भांड़ी गणे मांण ।
सिद्धपां छोडियो सिद्धपुर, दाखल मरू देसांण ।।

Translation: After fierce quarrels with the Chauhans in Siddhpur, the Siddhapas, proud of their heritage, migrated and made a home in the desert lands of Marwar.

चतुरभुज हुओ सिद्धप, सांपड़त जिम सांवत ।
पोकरणो छुडायो पलमें, जैसाणै जांवत ।।

Translation: Chaturbhuj, a true Siddhap, outwitted even powerful lords and freed Pokarna’s prince in moments, daring to confront the rulers of Jaisalmer.

In Phoolasar jagir, many Sindhi Muslims reside who are considered subjects (riaya) of the jagirdars. These include Manganiyars, the traditional bards who sing songs in praise of the Siddhap Rajpurohit family. They actively partake in the Rehan Sabha held during Diwali in the Kotdis of the Siddhap jagirdars.

Phoolasar continued its tradition of valor and leadership into the British and post-independence era. Notable individuals include:

• Gourav Singh Rajpurohit – IPS Officer

• Major Multan Singh Rajpurohit – Veteran of World War II

• Dr. Surya Pratap Singh Rajpurohit – Captain, Indian Army Medical Corps

• Hari Singh Rajpurohit – Income Tax Inspector

• Dalpat Singh Rajpurohit – Session Court Judge, Jodhpur

Many others from Phoolasar have served in police, defense, and civil services.

Even in contemporary times, the Siddhap Rajpurohits of Phoolasar are known for their service in the armed forces, public administration, law, and social reform.
