Why did the u. s. seek to expand its economic, military, political and cultural influence in
the second half of the 19th century?

As an industrial and economic might rose in the second half of the 19th century, the US developed a powerful navy and a modern army. It increased its exports and multiplied its economic interests abroad, as well as those of US investors. Economic growth came in tandem with technological progress. 1898 is a turning point on the US road to global intervention in world affairs. The war of independence in Cuba, fear of harm to American interests there, and a sense of opportunity led to the US declaring and fighting a brief but successful war with Spain. As a result, the US takes control of Puerto Rico, Cuba, the Philippines and Guam. There were already ambitions to build a canal in the Americas, though the opportunity came only in the 1910s. The US is now a real global power.
