The most popular lyrics to this
Republican song have two variants known as
El Paso del Ebro and
Viva la XV Brigada. The first one is related to the
Battle of the Ebro and the second mentions the
Battle of Jarama, two of the main confrontations of the Civil War. The sentence
Luchamos contra los moros (We fight against the Moors) refers to the
Regulares, the feared Moroccan units fighting as the
shock troops of the Nationalists. A Croatian singer and songwriter
Darko Rundek released a version of the song with
anti-fascist and anti-
oppressor lyrics in his 2000 album
U širokom svijetu. The song enjoyed widespread support among populations in the Serbian capital of
Belgrade, especially during the
2018–2020 Serbian protests. ==Lyrics==
