It is consider that both the sinking if the USS Maine and The Lusitania were factors in US entering two different wars (the war between US and Spain and the First World War).
The USS Maine was sunk in 1898 in Cuba. The battleship was near the Cuban coast while there was a conflict between Spain and Cuban nationalists fighters. It is believed that a mine was the cause of the explosion of the USS Maine resulting in the death of hundreds of men on board. There was already support in the US for the Cuban nationalist cause and the USS Maine incident galvanized the public opinion against Spain.
The Lusitania was sunk by a German submarine in 1915 near Ireland. The Lusitania was a civilian ship (although it was also carrying military supplies to England) and its sinking had a profound impact on public opinion. It helped the US goverment obtain popular support to declare war on Germany.
These countries were at war with each other, people of the U.S were very fearful during this time because of the threat of war and bombs planted in Cuba. World War 11 had ended years before So our country knew war as a way of life and they didn t want to have to endure that fight once again. The cold war was a time when all of these countries, especially the U.S and World War 2 was in a fight to be the biggest world power.
<span>American people benefited from industrial growth while also experiencing its adverse effects. Cheap labor and assembly-line manufacturing made mass production possible. Railroad networks carried the mass-produced goods, of new technologies, around the country. retailers expanded their operations and laid the foundation for the consumer-driven society that evolved later in the century. Materially, city dwellers' standards of living improved steadily, not only in food, shelter, housing, and other material goods, but also in health care and education. Inexpensive books, magazines, newspapers, and improved public libraries, funded in part through the benevolence of Andrew Carnegie, contributed to their intellectual lives. Sexual fulfillment in marital relationships continued to gain importance, and family life increasingly reflected the ideals of companionship. Silent films and amateur and professional sports helped fill leisure time. The Boy Scouts and Girl Scouts, founded in 1908 and 1910, provided recreational and educational opportunities for children.</span>
