Pierre François Joseph Benoit Rosalvo Bobo(1874–1929), known as Rosalvo Bobo, was a Haitian politician, and a leader of the rebel faction known as the Cacos. In March of 1915 he started and led a rebellion against the government of President Jean Vilbrun Guillaume Sam. With the rebellion going against him Guillaume Sam ordered the arrest and murder of his political opponents, and was himself killed by a mob in retaliation on 27 July 1915. This led to a breakdown of order and widespread violence in the capitol of Port-au-Prince. In response the United States landed U.S. Marines at Port-au-Prince on 28 July 1915, beginning the 1915 occupation of Haiti.
