The buttons all date to between 1902 and 1922. This was a very turbulent era in Dublin involving seminal moments in modern Irish history such as the 1913 Lockout, the Great War of 1914/18, the 1916 Rising, the War of Independence and the Civil War. (Though by the Civil War, these buttons were being replaced by the Póilíni Átha Cliath type insignia).
