Why did irishmen fight in the spanish civil war?

Irishmen fought in the Spanish Civil War for various reasons, including ideological commitment to anti-fascism, a desire to support the Second Spanish Republic, and personal convictions about social justice. Many were motivated by a sense of solidarity with the Spanish people's struggle against Franco's Nationalist forces, which were seen as a threat to democracy and workers' rights. Additionally, some Irish volunteers were influenced by the broader context of European politics and the rise of fascism during that era, prompting them to take action abroad.
