Given the question: Information: - World War I (WWI or WW1), also known as the First World War, or the Great War, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918. More than 70million military personnel, including 60 million Europeans, were mobilised in one of the largest wars in history. Over nine million combatants and seven million civilians died as a result of the war (including the victims of a number of genocides), a casualty rate exacerbated by the belligerents' technological and industrial sophistication, and the tactical stalemate caused by gruelling trench warfare. It was one of the deadliest conflicts in history, and paved the way for major political changes, including revolutions in many of the nations involved. - World WarII (often abbreviated to WWII or WW2), also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the world's nationsincluding all of the great powerseventually forming two opposing military alliances: the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. In a state of "total war", the major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, erasing the distinction between civilian and military resources. Marked by mass deaths of civilians, including the Holocaust (in which approximately 11 million people were killed) and the strategic bombing of industrial and population centres (in which approximately one million were killed, and which included the atomic bombings of Hiroshima and Nagasaki), it resulted in an estimated 50 million to 85 million fatalities. These made World WarII the deadliest conflict in human history. - The flag of the United States, often referred to as the American flag, is the national flag of the United States. It consists of thirteen equal horizontal stripes of red (top and bottom) alternating with white, with a blue rectangle in the canton (referred to specifically as the "union") bearing fifty small, white, five-pointed stars arranged in nine offset horizontal rows, where rows of six stars (top and bottom) alternate with rows of five stars. The 50 stars on the flag represent the 50 states of the United States of America, and the 13 stripes represent the thirteen British colonies that declared independence from the Kingdom of Great Britain, and became the first states in the U.S. Nicknames for the flag include The Stars and Stripes, Old Glory, and The Star-Spangled Banner. - The Battle of Baltimore was a sea/land battle fought between British invaders and American defenders in the War of 1812. American forces repulsed sea and land invasions off the busy port city of Baltimore, Maryland, and killed the commander of the invading British forces. The British and Americans first met at North Point. Though the Americans retreated, the battle was a successful delaying action that inflicted heavy casualties on the British, halted their advance and allowed the defenders at Baltimore to properly prepare for an attack. The resistance of Baltimores Fort McHenry during bombardment by the Royal Navy inspired Francis Scott Key to compose the poem "Defence of Fort McHenry", which later became the lyrics for "The Star-Spangled Banner", the national anthem of the United States of America. - Fort McHenry, in Baltimore, Maryland, is a historical American coastal star-shaped fort best known for its role in the War of 1812, when it successfully defended Baltimore Harbor from an attack by the British navy from the Chesapeake Bay September 1314, 1814. It was first built in 1798 and was used continuously by U.S. armed forces through World War I and by the Coast Guard in World War II. It was designated a national park in 1925, and in 1939 was redesignated a "National Monument and Historic Shrine," - George Henry Preble ( February 25 , 1816 -- March 1 , 1885 ) was an American naval officer and writer , notable for his history of the flag of the United States and for taking the first photograph of the Fort McHenry flag that inspired The Star - Spangled Banner . - "The Star-Spangled Banner" is the national anthem of the United States of America. The lyrics come from "Defence of Fort M'Henry", a poem written on September 14, 1814, by the 35-year-old lawyer and amateur poet Francis Scott Key after witnessing the bombardment of Fort McHenry by British ships of the Royal Navy in Baltimore Harbor during the Battle of Baltimore in the War of 1812. Key was inspired by the large American flag, the Star-Spangled Banner, flying triumphantly above the fort during the American victory. - The War of 1812 was a military conflict that lasted from June 1812 to February 1815, fought between the United States of America and the United Kingdom, its North American colonies, and its Native American allies. Historians in the United States and Canada see it as a war in its own right, but the British often see it as a minor theatre of the Napoleonic Wars. By the war's end in early 1815, the key issues had been resolved and peace returned with no boundary changes. - Old Glory is a nickname for the flag of the United States. The original "Old Glory" was a flag owned by the 19th-century American sea captain William Driver (March 17, 1803March 3, 1886), who flew the flag during his career at sea and later brought it to Nashville, Tennessee, where he settled. Driver greatly prized the flag and ensured its safety from the Confederates, who attempted to seize the flag during the American Civil War. After the war, Driver's daughter and niece feuded over which of them owned the original Old Glory.
