Star of David

The Star of David, also known as the Magen David, is a symbol of Jewish identity and Judaism that originated from a hexagram shape, consisting of two equilateral triangles. Its association as a distinct Jewish symbol dates back to 17th-century Prague, and it was widely adopted by Jewish communities in Eastern Europe in the 19th century, representing Jewish identity and religious beliefs. The symbol was chosen as the central symbol on the Jewish national flag at the First Zionist Congress in 1897, becoming a representative of Zionism and later the State of Israel's national flag, with its use becoming internationally accepted by the end of World War I.learn more on wikipedia
