Mohali, formally Sahibzada Ajit Singh Nagar, was made a district in 2006 and is named for the eldest son of Guru Gobind Singh Ji, who died at Chamkaur in 1704.
It is Punjab's newest urban district, effectively a planned extension of Chandigarh, and it holds the state's information technology parks, the international airport, the cricket stadium, IISER, the Indian School of Business campus and the National Institute of Pharmaceutical Education and Research.
It also holds Chappar Chiri, where Banda Singh Bahadur Ji defeated Wazir Khan in 1710, now on the edge of the built-up area.
Its urban expansion has taken agricultural land at a rate faster than anywhere else in Punjab, and its land prices are the highest in the state.
Kharar, Banur, Zirakpur and Dera Bassi are absorbing the growth.
What is not recorded: the villages this expansion has absorbed, whose names survive as sector names and whose histories do not.
The district was created in 2006 and named for the elder Sahibzada. Mohali itself was laid out as a planned extension of Chandigarh from 1975.
Land acquisition for all of this has been contested continuously. Compensation and the developed plot given in exchange have made some village families very wealthy and left others with nothing, depending on when their land was taken and under which scheme, and that split runs through every village in the district and is written down nowhere.
It is the only district in Punjab whose population is growing through people arriving rather than through births, and its land prices are the highest in the state.
