paragraph_text: The music and lyrics were written in 1873 by Kārlis Baumanis, a teacher, who was part of the Young Latvian nationalist movement. It has been speculated that Baumanis may have borrowed part of the lyrics from a popular song which was sung to tune of God Save the Queen, modified them and set them to music of his own. Baumanis's lyrics were different from the modern ones: he used the term "Baltics" synonymously and interchangeably with "Latvia" and "Latvians", so "Latvia" was actually mentioned only at the beginning of the first verse. Later the term "Latvia" was removed and replaced with "Baltics" to avoid a ban on the song. This has led to the misapprehension that the term "Latvia" was not part of the song until 1920, when it was chosen as national anthem and the word "Baltics" was replaced with "Latvia".During the annexation of Latvia by the Soviet Union, the singing of "Dievs, svētī Latviju!" was banned. The Soviet republic of Latvia had its own anthem. "Dievs, svētī Latviju!" was restored as the state anthem of Latvia on 15 February 1990, a very short period before Latvian independence was restored.
