As early as 1802 and 1819, Factory Acts were passed to limit the working hours of children in factories and cotton mills to 12 hours per day. These acts were largely ineffective and after radical agitation, by for example the "Short Time Committees" in 1831, a Royal Commission recommended in 1833 that children aged 11–18 should work a maximum of 12 hours per day, children aged 9–11 a maximum of eight hours, and children under the age of nine should no longer be permitted to work. This act, however, only applied to the textile industry, and further agitation led to another act in 1847 limiting both adults and children to 10-hour working days.
