Angell advocated peace, pacifism and international understanding. He had written "The Great Illusion" (1910), in which he claimed that it was an illusion that war could be profitable to a nation, and he maintained that this illusion was going to lead Europe into a state of war. Angell also wrote "America and The New World-State"(1912), "The World's Highway" (1916) and several other works. "The Unseen Assassins" (1932) described nationalism as the greatest threat to world peace.
The nomination of Angell received verwhelming support, especially in the USA.
Some of his political companions had initiated a campaign in favour of his candidacy, led by F.S. Cocks and Lord Snowden (members of the British parliament). A man called Mr. Wrench sent circulars (motivation based on the book "Unseen Assassins") around the world.
In 1934 Angell received the reserved Nobel Peace Prize for 1933.
