In the face of strong opposition from Democrats, Grant and Fish secured a free trade treaty in 1875 with the Kingdom of Hawaii, incorporating the Pacific islands' sugar industry into the United States' economic sphere. The Southern Democrats, wanting to protect American rice and sugar producers, tried to squash a bill to implement the Hawaiian treaty. The Democrats, in opposition, because the treaty was believed to be an island annexation attempt, referred to the Hawaiians as an "inferior" non-white race. Despite opposition, the implementation bill passed Congress.
