First and oldest Flag in this World

Flag of Denmark

This is the first and oldest flag in the world. According to Danish legend, the flag fell from the sky on June 15, 1219, to the Danish King Valdemar II, who on that day defeated Estonia in battle (this would make it the oldest national flag in Europe still in use). The first recorded use of this flag was in the 1300s.
