The title track of Steeltown by Big Country is about the loss of jobs in Corby.
By 1939 the population had grown to around 12,000, at which time Corby was thought to be the largest "village" in the country, but it was at that point that Corby was re-designated an urban district (see the Local Government section below).
In 1568 Corby was granted a charter by Elizabeth I that exempted local landowners from tolls (the fee paid by travellers to use the long distance public roads), dues (an early form of income tax) A popular legend is that the Queen was hunting in Rockingham Forest when she (dependent on the legend) either fell from her horse or became trapped in a bog whilst riding.
Upon being rescued by villagers from Corby she granted the charter in gratitude for her rescue.
Mesolithic and Neolithic artefacts have been found in the area surrounding Corby and human remains dating to the Bronze Age were found in 1970 at Cowthick.
The first evidence of permanent settlement comes from the 8th century when Danish invaders arrived and the settlement became known as "Kori's by" – Kori's settlement.
