From the mid-1200s until the early-1600s, the Galloglass transformed Irish warfare. Presenting the Galloglass Database online would not be possible without the combined efforts of many people. In its formative stages, the data for the project was compiled by Dr Susan Foran at the Centre for Irish-Scottish and Comparative Studies, Trinity College Dublin (TCD), supervised by Professor Seán Duffy. It is most appropriate the Galloglass Database should find its home with the Corpus of Electronic Texts (CELT) at University College, Cork (UCC). Founded by Professor Donnchadh Ó Corráin, the CELT textbase is free and represents Ireland's longest running online resource for Irish history, literature and politics.

This marks a significant intervarsity collaboration between two Humanities Computing projects. Moreover, CELT's digital editions include many of the original texts which serve as the principal sources for Galloglass history. The most prominent examples are, of course, the Irish Annals. In 2005, the Galloglass collaboration between TCD and CELT was copper-fastened by Professor Ó Corráin and Professor Duffy. The subsequent completion of this project owes much to the impetus provided by Dr Hiram Morgan, the current director of CELT, with financial assistance from PRTLI Cycle 4. James Northridge and Mike Cunneen of Abeo Web Solutions have marshalled the data and prepared the webpages. Peter Flynn, Webmaster and Manager of the Electronic Publishing Unit at UCC, has provided essential support at this stage of the process. We are also grateful to Beatrix Färber, CELT Project Manager, and the renowned historian, Kenneth Nicholls, who have been generous and co-operative in their dealings. We wish to thank the following people for their help obtaining permission to use images to illustrate the webpages: Andrew Halpin and Finbarr Connolly of the National Museum of Ireland, Joanne Clarke, Curator at the GAA Museum, Croke Park, and Nollaig Feeney, Heritage Officer at Roscommon County Council.
