The flag of Iceland (Icelandic: íslenski fáninn)[1] was officially described in Law No. 34, set out on 17 June 1944, the day Iceland became a republic. The law is entitled "The Law of the National Flag of Icelanders and the State Arms" and describes the Icelandic flag as follows:
Iceland's first national flag was a white cross on a deep blue background. It was first shown in parade in 1897. The modern flag dates from 1915, when a red cross was inserted into the white cross of the original flag. This cross represents Christianity.[2][3] It was adopted and became the national flag when Iceland gained independence from Denmark in 1918. For the Icelandic people the flag's colouring represents a vision of their country's landscape. The colours stand for 3 of the elements that make up the island. Red is the fire produced by the island's volcanoes, white recalls the ice and snow that covers Iceland, and blue is for mountains in the distance.
