After the formation of the party, the party leaders reached out to Henry George, who was sympathetic enough to labor to run under a labor banner but also educated enough to be a viable candidate, who eventually agreed to run for the United Labor Party after seeing 36,000 signatures in support of him.[1][3] The party ran for the New York City mayoral position in 1886 with the candidate Henry George, who ended in second, ahead of Republican Candidate Theodore Roosevelt and behind the Democratic Candidate Abram Hewitt.
After the two elections, there was heavy conflict between the Georgist faction of the party and the Socialist faction of the party, eventually ending in a Georgist-Socialist split in 1887, which effectively ended the alliance.[1][5]
