Prior to 500 AD the 24-rune Elder Futhark was used in Sweden. From 500 AD until 800 AD there were many Futharks which were transitions from the 24-rune Futhark to one of the 16-rune Futharks. By the end of this period the 24-rune Futhark was completely out of use , and only 16-runes Futharks were in use. By 900 AD two different types of Shorttwigs-Futharks had been born. One was popularized in Norway and the other was used in the west (the British islands). By 1000 AD the adjustment of the runes to the Latin alphabet had begun, and several versions are found up until the Dalrunes, about 1700-1800 AD.
