Butler clan were Thomas Butler, 10th Earl of Ormond (a.k.a. Black Tom) who built the Tudor Manor House extension to Ormonde Castle and James the 12th Earl and 1st Duke of Ormond, who founded the town's woollen industry in 1670. Edmond le Bottiler erected two large, heavily garrisoned castle keeps named the Plantagenet Castle on the north bank of the Suir, just east of what is now Main St. In the 15th century, a four towered castle was erected on the same site, two of which are now incorporated into the Elizabethan Manor House built by Black Tom Butler, c. 1560. The Manor House, where Archbishop Dermot O'Hurley, one of the most celebrated of the 24 Irish Catholic Martyrs, was arrested in 1583, still stands today, having been extensively refurbished by the Irish State in the 1990s and is open to the public. The town was also the inspiration for the 16th-century song, Cailín ó chois na Siúire mé, which is attested to as early as 1595 and mentioned in William Shakespeare's Henry V as Caleno custure me. In 1649, the town was taken by English Parliamentarians during the Cromwellian conquest of Ireland. They captured Carrick by stealth after discovering an undefended gate as part of operations during the Siege of Waterford. Irish troops from Ulster under a Major Geoghegan tried to re-take Carrick but were eventually beaten off with the loss of over 500 killed. In 1670 the Butlers set up a woollen industry in the town. By 1799, the town enjoyed some prosperity from the woollen industry, fishing, basket weaving and other river-related businesses – the population reached around 11,000 by this point. In that year, a barge capsized on the river near the bride, resulting in the deaths of around 91 people. Over the next 120 years however, the town suffered from high taxes and levies imposed by the British on the woollen industry, leading to high unemployment, poverty and emigration. The Great Famine also contributed greatly to the depopulation of the town. 20th century With the coming of Independence and the Civil War, Carrick was initially occupied by the Anti-Treaty IRA until the town fell to the Free State army in 1922. By this stage, industrialisation had reached Carrick with the establishment of cotton factories and a local creamery. Most significant however for the economic development of the town was the arrival of the tanning industry
