When talking corsetry, the most interesting period of fashion is the period from 1820 to about 1910. But the corset is much older than that.

The corset has at all times been used for shaping the body, most often for compressing the waist, but sometimes for raising the bust. The most widespread use of corsets was in the 19th century. Contrary to common belief, almost all women of every class wore corsets in those times.
