what is the song zombie about

"Zombie" is a protest song by the Irish alternative rock band The Cranberries, written by the bands lead singer Dolores ORiordan about The Troubles in Northern Ireland). The song was released on September 19, 1994, as the lead single from their second studio album, No Need to Argue (1994), two weeks ahead of the albums release). The lyrics of the song speak about the Irish fight for independence that seems to last forever. The title of the song and its chorus is likely a reference to mindless troops, just following what the authorities say, killing or harming with no personal thought on the matter. The songs message combined with the singers warbling voice created both a great deal of tension and reason to take action. The song became a worldwide hit, reaching No.1 in several countries and winning the Best Song award at the 1995 MTV Europe Music Awards.
