At the end of the 13th century, Edward I commissioned Roger de Montgomerie to construct a centre for the hamlet of Llanfair-yng-Nghedewain. Situated near a River Severn ford below the Long Bridge and close to the church of St Mary in Bettws Cedewain gave Newtown its original Welsh name. The foundation is connected to the fate of Llywelyn ap Gruffudd, Prince of Wales, whose new administrative centre at Dolforwyn Castle near Abermule so alarmed Edward I that it was besieged. He seized Llywelyn's lands and granted them to the Mortimers. They transferred the administration of the cantref of Cedewain and the commote of Ceri from Dolforwyn Castle to the new settlement at Newtown. The town grew in the 18th and 19th centuries around the textile and flannel industry, stimulated by completion of the Montgomeryshire Canal. In 1838, the town saw Wales's first Chartist demonstration. The Cambrian Mills, opened in 1856, were the first steam-driven mills in Newtown. The mills stood beside the canal terminus on the east bank of the Severn. They expanded to become the largest of the Welsh woollen mills. However, by the end of the 19th century the Newtown mills were no longer competitive with those in the north of England. There was a disastrous fire in 1910 and another in 1912, after which the Cambrian Mills were not rebuilt. Thereafter Newtown was no longer an important centre of the woollen industry and many workers moved elsewhere. Newtown hosted the National Eisteddfod in 1965. In 1967, the town was designated a new town. It saw a large population growth as firms and people settled, changing its rural market town character.

Government
Newtown was governed at local level by Newtown Urban District Council, until this was replaced by Newtown and Llanllwchaiarn Town Council under the Local Government Act 1972. The local government community is Newtown and Llanllwchaiarn, though commonly known as Newtown. Today's Town Council has 16 elected members serving five-year terms, and employs a staff of about ten. It deals mainly with green spaces and public facilities, and as a representative voice for Newtown. The Council Chair or Mayor, elected by the councillors, has been Councillor Sue Newham since 2017. The community is represented on Powys County Council by five county councillors, each representing a ward: Newtown Central, Newtown East, Newtown Llanllwchaiarn West, Newtown Llanllwchaiarn West and Newtown South.
Built by Pryce Pryce-Jones, the Pryce Jones Royal Welsh Warehouse remains the tallest building in Newtown. The two towering structures housed the world's first mail order service depot. Bear Lanes, the town's main shopping centre, has a Tudor-style entrance. The building was once a hotel, The Bear, which contributes to the centre's appearance today. The Robert Owen Museum is on the ground floor of the council offices in Brisco House, Broad Street. A statue of Robert Owen was erected in 1956 in a park off Shortbridge Street and Gas Street. A replica of this was later erected in Manchester. The Free Library building designed by the architect Frank Shayler of Shrewsbury was built in 1902. The Baptist Chapel, dating from 1881, is a fine example of nonconformist architecture from that period. The Back Lane drill hall was completed in 1897.

Schools
The Newtown schools are Ysgol Cedewain, Ladywell Green, Hafren Junior, Ysgol Dafydd Llwyd, St Mary's, Penygloddfa, Maesyrhandir, Treowen, and Newtown High School and Sixth Form. The last recently received an outstanding Estyn inspection report in October 2015, praising many features, including teacher/sixth-form pupil relations and school support for a wide range of post-16 vocational and academic subjects. As of 2011, it was proposed that Newtown High School, along with several other schools in Powys, should merge with another county high school, as part of Powys County Council's secondary school and post-16 modernisation programme.
