Explain how the yellow press affected relations between the united states and spain

The Spanish-American relations was affected by the yellow press because of the Spanish-American war - that is considered the first "media war".

The Spanish-American war was fought in 1898 between the US and Spain. It started because of the explosion of USS Maine that was in Havana Harbor and the main issue of the war was Cuba independence.

When the USS Maine exploded "New York Journal" published a story blaming the Spanish for what occurred. The newspaper used eye-catching headlines, sensational stories with the feature of yellow.

This influenced the public's opinion who demanded intervention and pushed the US to enter the conflict with Spain over Cuba.
