Months after the death of Kaʻiulani's mother, Likelike, political unrest gripped Hawaii. Local businessmen accused Kalākaua's cabinet under Prime Minister Walter Murray Gibson of influence peddling in elections and manipulation of legislative governance. Although the Gibson cabinet was replaced by the Reform Cabinet, the business community remained dissatisfied. The Committee of Thirteen businessmen under the leadership of Lorrin A. Thurston, drafted what became known as the Bayonet Constitution, codifying the legislature as the supreme authority over the monarchy's actions. Thurston is believed to have been the principal author of the new constitution. Presented to Kalākaua for his signature on July 6, 1887, it limited the power of the monarchy and increased the influence of Euro-American interests in the government.
