Today is flag day, which got me thinking about the history of flags. I went to wikipedia.com and found some interesting facts about flags.
- Flags were used in the middle ages to identify a knight.
- Ships began using flags in the 17th century to show their country of origin and to communicate.
- The flag of Denmark was designed in 1478, and is the oldest national flag still in use.
- Flags are also used for religious purposes, such as the Buddhist prayer flags.
