The South Korean boy band BTS is now the first K-pop group to reach No 1 on the Billboard top 200.
Love Yourself: Tear sold 135,000 units for the week ending May 24, as tallied by Nielsen Music.
According to Billboard, Love Yourself: Tear is also the first primarily foreign-language album to top the charts since Il Divo's Ancora in 2006.
The seven-member group, also known as the Bangtan Boys, has a devoted core of fans known as "the army" and its appeal has been likened to Beatlemania in the 1960s.
BTS is at the heart of a global trend known as "Hallyu," or "Korean Wave."
Their albums include Dark & Wild and 2 Kool 4 Skool.
