The town of Ammanford is a relatively modern settlement. It was originally known as Cross Inn, named after an inn that was located at a location where a number of roads converged. During the nineteenth century, as a result of the growth of both the tinplate and anthracite coal trades, a village grew around the Cross Inn. As the settlement expanded, prominent residents came to the view that its name should be changed since there were a number of other places named Cross Inn in Carmarthenshire alone. In 1880, a number of public meetings were held, and in November 1880 it was resolved that the name 'Ammanford' be adopted. The meeting was chaired by Watcyn Wyn. It took several years for the new name to be widely adopted, but the decision of the Great Western Railway to change the name of the Cross Inn station to Ammanford in June 1883 was welcomed by residents and tradesmen.
Government
Parliamentary Elections
Ammanford was part of the Carmarthenshire county constituency until it was divided in 1885 whereupon the town was located in the East Carmarthen constituency which was held until its abolition in 1918 by the Liberal Party. The Labour Party captured Llanelli in 1922 and have held it ever since. The MP from 1936 until 1970 was Jim Griffiths, a native of nearby Betws. However, in 1997, Ammanford was transferred to the new Carmarthen East and Dinefwr seat which was captured in 2001 by Adam Price of Plaid Cymru.
Local Government
Ammanford was part of Carmarthenshire County Council from 1889 until 1974 and was usually represented by Labour councillors. It became part of Dyfed County Council from 1974 until 1996. Following the abolition of Dyfed it became, once again, part of Carmarthenshire, now a unitary authority. Ammanford Urban District Council was formed in 1903 in consequence of sharp population growth. It was absorbed into Dinefwr Borough Council upon re-organization in 1974. Dinefwr in turn was absorbed into the Carmarthenshire unitary authority in 1996. Ammanford's Town Council has continued as a community council. The community is bordered by the communities of: Llandybie; Betws; and Llanedi, all being in Carmarthenshire.
Religion
Ammanford is in the ecclesiastical parish of Ammanford and Betws. Ammanford formed part of the ancient parish of Llandybie although the parish church at Betws was much closer to the town. The established church was, however, slow to react to the growth of an urban community. The nonconformist denominations, in contrast, were far more active and Ammanford was an important location as the 1904–1905 Welsh Revival unfolded. Prominent chapels include Ebenezer, Gelliamnwydd and Bethany. There is an active Christadelphian community based in the town centre.
Twentieth century
The Ammanford Anthracite Strike was a riot at Ammanford in 1925 during a strike by anthracite miners who took control of the town by force and violence for 10 days. 200 Glamorgan police were ambushed by strikers at Pontamman Bridge during the so-called 'Battle of Ammanford'. Ammanford hosted the National Eisteddfod in 1922 and 1970.
