Ireland's Military Archives are available online for the first time.
The Archives, which are held in Cathal Brugha Barracks in Rathmines in Dublin, can now be accessed via a new website - militaryarchives.ie.
The site has been launched in conjunction with the National Archives of Ireland, and is designed to appeal to historians, genealogists and members of the public researching their family tree.
By March, it plans to publish the Bureau of Military History Collection 1913 to 1921, online, including 36,000 pages of witness statements, digitised and fully word searchable.
This will be followed by the first release of the Military Service Pensions Project - material which the Defence Forces say "will provide a major and never before seen insight into the 1916 Rising and the War of Independence in particluar".
