A month after the Spanish Civil War began in 1936, several players from Barcelona enlisted in the ranks of those who fought against the military uprising, along with players from Athletic Bilbao. On 6 August, Falangist soldiers near Guadarrama murdered club president Josep Sunyol, a representative of the pro-independence political party. He was dubbed the martyr of barcelonisme, and his murder was a defining moment in the history of FC Barcelona and Catalan identity. In the summer of 1937, the squad was on tour in Mexico and the United States, where it was received as an ambassador of the Second Spanish Republic. The tour led to the financial security of the club, but also resulted in half of the team seeking asylum in Mexico and France, making it harder for the remaining team to contest for trophies.
