Long before it named an airport or a neighborhood, "Tân Bình" named nearly the entire future city of Saigon — a scale of naming this small district has never come close to matching since.
Under Lord Nguyễn, Tân Bình huyện (district) becomes the sole district of Phiên Trấn dinh, an administrative unit covering most of what is now Ho Chi Minh City — the first and by far the largest use of a name that today labels one district among many.
Tân Bình is elevated to a phủ (prefecture); the name persists through the 19th century even as the territory it describes keeps shrinking with each administrative reform.
French colonial authorities build an airstrip on the elevated, well-drained land of Tân Sơn Nhứt village — chosen precisely because it sat higher and drier than most of the surrounding area, ideal ground for an early airfield.
The first direct Hanoi–Saigon flight departs, taking eight and a half hours.
The airfield receives its first flight from Paris — a journey that takes 18 days.
Following the Geneva Accords, waves of mostly Catholic migrants from northern Vietnam resettle on what was then rice paddy and rubber plantation land near a three-way intersection — the beginning of the Ông Tạ neighborhood; see Anecdotes, below.
With American support, the airport's runway is rebuilt in concrete and extended past 3,000 meters, replacing the original 1,500-meter dirt strip laid down by the French.
Tân Bình district is formally established by the Republic of Vietnam government, carved from Gò Vấp district's Dương Hòa Thượng canton. Its seat is placed in Phú Nhuận commune.
The old district is dissolved after reunification, then re-established in 1976 through the merger of two short-lived districts, Tân Sơn Hòa and Tân Sơn Nhì, becoming for a time the largest district in the city by area.
Tân Phú district splits off from Tân Bình's western portion, reducing it to its current boundaries.
A citywide ward reform redraws Tân Bình's internal boundaries once more — its fifteenth reorganization since the name first appeared on this land in 1698.
