Borglum was active in the committee that organized the New York Armory Show of 1913, the birthplace of modernism in American art. By the time the show was ready to open, however, Borglum had resigned from the committee, feeling that the emphasis on avant-garde works had co-opted the original premise of the show and made traditional artists like himself look provincial. He moved into an estate in Stamford, Connecticut in 1914 and lived there for 10 years. He sheltered Czechoslovak Legion members on his land at Stamford in 1917.
