Smetana married Kateřina and they had four daughters, but three of them died. He still had very little money, so he went to Sweden where he was very successful as a piano teacher and conductor. He composed the first of his symphonic poems: "Richard III". After three years in Sweden he decided to return to his homeland because of his Kateřina’s health, but she died on the way. Smetana spent two more years in Sweden. He married again. After the Austrian defeat by Napoleon III in 1859, it became clear that there were going to be big changes in his native country. The Czechs were going to be allowed to have a national opera and put on plays in the Czech language instead of having to perform everything in German. Smetana realized that this was an exciting chance for him. After a big farewell concert in Stockholm to which the Swedish royal family came, Smetana returned to Prague.
