When was the latvian flag invented?

The Latvian flag, featuring a red field with a white horizontal stripe, is believed to have been created in the early 13th century. It was officially adopted as the national flag in 1921, following Latvia's Declaration of Independence from Russia in 1918. The design symbolizes the blood shed by the Latvian people in their struggle for freedom and the white represents peace and truth. The flag has undergone several iterations throughout history but has remained a symbol of Latvian identity and sovereignty.
