The Danube is the second longest river in Europe. It flows through nine countries. The name of the Danube comes from a story. According to legend, there was a hero named Ivan Donault in ancient times. He married the heroine Tasha and boasted of his invincible martial arts at the wedding banquet. The bride laughed at him for being too arrogant, so she forced her to compete with him in archery. As a result, he lost, and the angry Ivan Donauer shot his wife with an arrow. Later, he repented and committed suicide in shame. His blood became a long river, the Danube. Therefore, the Danube is named.
