History and population Železnik village was founded in the 17th century. Construction of the modern settlement began in 1947, as a worker's settlement for the employees of the newly constructed Ivo Lola Ribar factory. Soon, plans were made for a completely new settlement, a major and heavily industrialized suburb of Belgrade (Železnik, Serbian for Iron City), with a population of 80.000, but that goal is not achieved. Some 15,600 of youth workers participated in the construction of the new town through the Youth work actions. Until the 20th century, Železnik was separated from Žarkovo, and further to the north from Belgrade, by lush forests.

The 1960s General urban plan of Belgrade envisioned the urban joining of Kneževac-Kijevo and Železnik, along the Kružni put road, creating a secondary center of Belgrade.

The city was to have numerous business buildings, department stores, hotels, educational facilities, scientific venues and medical institutes. The project wasn't carried through and the two neighborhoods remained disconnected, though they both independently formed one urban unit with Belgrade in time and in 1972 were abolished as separate settlements and annexed to Belgrade as its neighborhoods. Formerly a separate municipality, it was a separate town until 1972, when was administratively annexed to the Belgrade City proper.
