EXPLANATIONS BELOW
Concept note-1: -Yellow journalism, the de Lome letter, annexing Hawaii and the explosion of the Maine lead to the Spanish American War. False, annexing Hawaii was not a cause of the Spanish American War.
Concept note-2: -The dramatic style of yellow journalism contributed to creating public support for the Spanish-American War, a war that would ultimately expand the global reach of the United States.
Concept note-3: -Yellow journalism did not, ultimately, start the war on its own; it was the sinking of the USS Maine that provided the trigger, not some fabricated story created by Hearst of Pulitzer.
Concept note-4: -Publication of the letter helped generate public support for a war with Spain over the issue of independence for the Spanish colony of Cuba.
Concept note-5: -The American “yellow press” blame Spain in banner headlines, outraging the public and inciting the rallying cry, “Remember the Maine! To hell with Spain!” Over 260 crew members perish in this event, which was a contributing factor in the outbreak of the Spanish-American War.
