The story begins in 1219, although the legend itself dates back to the 16th century. According to it, Waldemar II of Denmark (Wald the Victorious) led a campaign in the region now known as Estonia. The stories recorded by Petrus Olai indicate that the battle did not go well. For some time, the Danes were convinced that they would lose the battle. However, the Danish bishop Anders Sunesen was not ready to give up. He stood on top of a hill overlooking the battle and prayed to God. While he prayed, the Danes began to regain their strength. When the bishop raised his hands, the Danes rushed forward and the Estonians retreated. Eventually, Anders Sunesen became so tired that he let his arms drop, and the Danes lost the advantage again. With the help of two soldiers who helped him hold his arms, Anders continued the fight, and Dannebrog must have fallen from the sky in some miraculous moment. King Waldemar picked up the cloth and showed it to his soldiers. Obviously, their hearts were suddenly filled with strength and courage, allowing them to go forward and eventually win the battle.
This story may seem a bit dramatic, but it is something that is very much in the hearts of the Danes. The story of Dannebrog is a source of local pride, and something that other countries have been trying to replicate for years.
There is a story about the Swedish flag that very closely mimics the Danish legend. In this story, the Swedes say that during one of the battles, a golden cross appeared in the sky.
In 2019, the legend of the Danish flag turned 800 years old. The legend was first mentioned by historians in the early 16th century. Since 1913, the flag day (and the legend of its origin) has been celebrated every year on June 15, and the day itself was named "Waldemar's Day" in honor of the late king. On this day, the flag is raised all over the country.
Although King Waldemar's crusade did take place, the legend of the flag's fall is obviously not based on historical facts. However, this does not make it any less significant.
