Although a law on the national anthem did not exist, the anthems of all three South Slavic nations were unified into a single anthem of the Kingdom. It started with the first part of the Serbian anthem "
Bože pravde", continued with the first verse of the Croatian anthem "
Lijepa naša domovino", which were in turn followed by first verse the
de facto Slovenian anthem "
Naprej zastava slave". The anthem finished with the refrain of the first verse of the Serbian anthem again. It was officially used between 1919 and 1941; there was no official document that declared it invalid or void. The Constitution of the Kingdom of Yugoslavia was not in effect after the
April capitulation. ==Lyrics==
