Woody Guthrie wrote "This Land Is Your Land" in 1940 after arriving in New York from Oklahoma. Over time, he changed the lyrics and performed it different ways. Many artists later performed the song to share Guthrie's message against social injustices. Known as the "people's troubadour," Guthrie used his music to unite people and fight oppression during the Depression era. His legacy continues to inspire artists today through his simple yet politically impactful songs that belong to all people.
