Hollinwood, in pre-industrial times, was a moor or common of Chadderton, but was largely incorporated into neighbouring Oldham following a court case in 1713. In the mid-18th century a village emerged at Hollinwood along the common border of Oldham and Chadderton, and there were further exchanges of land at Hollinwood between Oldham Borough and Chadderton township in 1880. "Chadderton (Detached)" was, as its name implies, a detached area or exclave of Chadderton. Lying under Copster Hill in Oldham and including the area now known as Garden Suburb, its area was absorbed into neighbouring Oldham in 1880.
