Following the Easter rising in 1916 there was a civil war until 1921
when the southern part of the island was granted dominion status with
Britain as the Irish Free State. Six northern counties continued to be
united with Britain as Ulster. The first stamps issued by the Free
State included a map stamp showing the island of Ireland under the
word "Eire," which in Gaelic means "Ireland, one and undivided." The
government of the Free State denied any political motivation, and said
intended to show the whole of the island of Ireland.
