EXPLANATIONS BELOW
Concept note-1: -Ostensibly on a friendly visit, the Maine had been sent to Cuba to protect the interests of Americans there after a rebellion against Spanish rule broke out in Havana in January. An official U.S. Naval Court of Inquiry ruled in March that the ship was blown up by a mine, without directly placing the blame on Spain.
Concept note-2: -Who was to blame? Spain controlled Cuba at the time. So, was it Cuba, or Spain, or was it an accident? Many people in the United States blamed Spain (Today, however, many historians believe a malfunction in the ship caused the explosion).
Concept note-3: -President William McKinley sends the battleship USS Maine to Havana to protect U.S. interests in Cuba. The Maine explodes in Havana Harbor, killing 266 men. An inquiry conducted by the U.S Navy concludes that the explosion was caused by the detonation of a mine under the ship.
Concept note-4: -The USS Maine was also a ship. The explosion killed 266 American sailors. Today, historians believe the explosion was an accident. In 1898, the U.S. blamed the explosion on Spain.
Concept note-5: -In 1897, newly elected President William McKinley cautioned patience, but the explosion of the Maine shattered U.S. relations with Spain and led to a declaration of war on April 25, 1898. War with Spain caused the U.S. to rethink its long-held principle of anti-colonialism.
