In the 11th century, Kosmas, a famous historian, wrote about the legends that surrounded the foundation of Prague. In his chronicles, Princess Libuše who ruled the Czechs somewhere in the 5th century, sent out a legation to find the place she saw in her dreams: “I see a great castle whose glory shall touch the Heavens …”
After this prophecy, the bases of today’s Prague Castle were built and Czech rulers have lived there ever since. In fact, the Slavic tribes did invade Middle-Europe in the fifth century. The first state in the Czech area was Samo’s Empire. Samo was a Franc merchant who formed a community with the Slavic people and decided to settle down on their land. Along came a period of prosperity and political independence, but all ended after his death and we have very little information about Samo himself.
