It is believed that around 1000 years ago a man named Nanda or Nandoo, who was a milkman from nearby village Katara, populated this village and the village named after him. It is also believed that during the British Raj, this town couldn't be captured, so people called it "Na Dabi", which means "not captured"; later it become Nadbai.
The town is also known as Asifabad. According to some legends the town was attacked and confiscated by a smaller group of soldiers led by knight of Mohammad Ghori, Asif Khan aka Yusuf Zai Ghaznavi and drove the locals out. The town was granted to Asif Khan and his soldiers as a reward by the Sultan. Asif Khan flourished the town/village and named it Asifabad which is currently documented in the royal decree. Current landscape and architecture including buildings and mosques appears to prove that this land has seen great scholars and high-ranked individuals. This town had High Court and police headquarters for the kingdom and was directly connected to the Royal Court.
The royal messages and documents used to be addressed directly to Qazi Shai and Qazi Yoonus. Later In 1773 the town was captured by Mirza Najaf Khan and ruled till 1782, when the Jat rulars of Bharatpur at that time took control of Nadbai. During the rule of Mirza Najaf Khan, a significant population of Sunni sect muslims were forced to migrate to other cities, as he wanted to convert them into Shia sect for which they refused at any cost.Thereafter, as a result of confiscation of land and properties of sunni muslims and brutalities by Mirza Najaf Khan, majority of Asifians moved to various regions of Rajputana (ie. Kota, Jhalawar, Bundi, Ajmer towns), and various adjacent states of India at that time. Just after partition of the sub continent, in 1947, and afterwards also, hundreds of Asifian (Nadbayyan) families migrated from various regions of Rajputana, voluntarily, to Pakistan side. Majority of them opted to settle in the Sindh province of Pakistan (mostly in Karachi, Hyderabad and Sukkur regions). In Karachi, at present, there is a registered housing society and its office which is located at Block 17 of Federal B Area in Karachi central.In this housing society, which was named as Asifia co-operative Housing Society, at present, a significant population of Asifians are residing. The Asifians are contributing in all walks of life in the Pakistani society as educationists (e.g. Prof. Dr. Hamid Mahmood PhD, and Prof. Dr. Moinuddin Ghori PhD), civil service (e.g.Khwaja Altaf Husain Ghori, Mohammad Masood Ahmed Qureshi and Umar Daraz Khan Ghori), doctors (e.g. Dr. Mughis Sheerani), business (e.g. Syed Sarfaraz Ali Ghori), fine arts (e.g. Saleemuddin Ghori), sports (e.g.test cricketers Alimuddin and Asad Shafiq) etc. Now a days Nadbai is also famous in Rajasthan by the name of Mini Kota as students from various district of Rajasthan come to Nadbai for study up to senior secondary.
