He was chief recorder at the Constitutional Convention in 1787 and supported ratification in the Federalist Papers, written with Alexander Hamilton and John Jay. In 1789, Madison was elected to the House of Representatives, where he helped frame the Bill of Rights and fought against passage of the Alien and Sedition Acts. In the 1790s, he helped found the Democratic-Republican Party, which ultimately became the Democratic Party. He became Jefferson’s secretary of state in 1801. Madison was elected president in 1808. His first term was marked by tensions with Great Britain, and his conduct of foreign policy was criticized by the Federalists and by his own party. Nevertheless, he was reelected in 1812, the year war was declared on Great Britain. The war that many considered a second American Revolution ended with a treaty that settled none of the issues. Madison’s most important action after the war was demilitarizing the U.S.-Canadian border. In 1817, Madison retired to his estate, Montpelier, where he served as an elder statesman, "the last of the fathers." He edited his famous papers on the Constitutional Convention and helped found the University of Virginia, of which he became rector in 1826. He died June 28, 1836.

During the Spanish-American War, in the battle of Manila Bay (May 1, 1898), an American squadron under Commodore George Dewey destroyed the Spanish fleet off Cavite within a few hours. The Manila Bay area was the focus, during the early phase of World War II, of a desperate attempt to save the Philippines from Japanese conquest. In the Allied recovery of the Philippines, many Japanese ships were sunk in the bay. The large U.S. naval base on Sangley Point was closed down in the early 1980s.

Probably the greatest English dramatist before Shakespeare, Marlowe was educated at Cambridge and he went to London in 1587, where he became an actor and dramatist for the Lord Admiral's Company. His most important plays are the two parts of Tamburlaine the Great (c.1587), Dr. Faustus (c.1588), The Jew of Malta (c.1589), and Edward II (c.1592). Marlowe's dramas have heroic themes, usually centering on a great personality who is destroyed by his own passion and ambition. Although filled with violence, brutality, passion, and bloodshed, Marlowe's plays are never merely sensational. The poetic beauty and dignity of his language raise them to the level of high art. Most authorities detect influences of his work in the Shakespeare canon, notably in Titus Andronicus and King Henry VI. Of his non-dramatic pieces, the best-known are the long poem Hero and Leander (1598), which was finished by George Chapman and the beautiful lyric that begins "Come live with me and be my love." In 1593, Marlowe was stabbed in a barroom brawl by a drinking companion. Although a coroner's jury certified that the assailant acted in self-defense, the murder may have resulted from a definite plot, due, as some scholars believe, to Marlowe's activities as a government agent.

Massachusetts entered the Union on February 6, 1788, as the sixth of the 13 original states. It early became an important intellectual center, known for Harvard University and the cultural institutions of Boston. In the 19th century, it developed into a major manufacturing state, noted for textiles and footwear; in the mid-20th century, electronic components and other high-technology items became leading manufactures. Massachusetts is famous for its summer resorts, such as the sand beaches of Cape Cod. Presidents John Adams, John Quincy Adams, and John F. Kennedy were born in the state and President Calvin Coolidge spent most of his life here. The name of the state is probably derived from an Algonquian Indian village and may mean "place of big hills." Massachusetts is called the Bay State.

Mercury Lane - Mercury, in the solar system is the planet closest to the sun. Its mean distance from the sun is approximately 58 million km (about 36 million mi); its diameter is 4875 km (3030 mi); its volume and mass are about 1/18 that of the earth; and its mean density is approximately equal to that of the earth. Mercury revolves about the sun in a period of 88 days. Radar observations of the planet show that its period of rotation is 58.7 days, or two-thirds of its period of revolution. The planet, therefore, rotates one and a half times during each revolution. Because its surface consists of rough, porous, dark-colored rock, Mercury is a poor reflector of sunlight.

Miami Street
- The Miami area was long inhabited by Indians. The first permanent non-Indian settlement was established in the 1870s near the site of U.S. Fort Dallas, which had been built (1835) during the Seminole Wars. Expansion began after the railroad magnate Henry M. Flagler (1830-1913) extended a railroad to the site in 1896 and promoted the city as a resort area. The Florida land boom of the mid-1920s led to rapid development, and during World War II several federal administrative and military agencies were established here. Large numbers of refugees from Cuba and other persons of Hispanic background settled in Miami beginning in the 1960s. Occasional hurricanes, notably in 1926, 1935, and 1992, caused considerable damage to the city and surrounding area. The name of the city may have been derived from a Tequesta Indian term for "big water," perhaps referring to Lake Okeechobee.

Middle Dunstable Road - This road was named after Dunstable which used to encompass the area in which Nashua is located.

The Mohawk were the easternmost member of the Iroquois confederacy.

Mohegan Drive - Mohegan Drive was named after the Mohegan Indians who lived on the Hudson River Valley in New York in the 1500s. After the settlers colonized the area and wiped out much of the tribe, they were put on a small reservation and later given rights to run casinos. These native North Americans spoke a language that belongs to the Algonquian branch of the Algonquian-Wakashan linguistic stock. Also called the Mohican, they were the eastern branch of the Mahican. In the early 17th cent. the Mohegan occupied most of SE Connecticut, their chief village being on the site of the present village of Mohegan on the Thames River. When European settlers arrived in this region, the Mohegan and the Pequot were one tribe, living under the rule of Sassacus. Later Uncas, a subordinate chief, rebelled against Sassacus and assumed the leadership of a small group on the Thames River near Norwich. This group was known as the Mohegan. After the fall of Sassacus the greater part of the Pequot joined the Mohegan, who in 1643 numbered some 2,300. The Mohegan, supported by the British, became one of the most powerful tribes in S New England. As white settlements were extended, the Mohegan sold most of their land and accepted a reservation on the Thames; others joined with neighboring tribes. By the early 19th cent. the Mohegans were practically extinct, although they became known to the world with the publication in 1826 of James Fenimore Cooper's novel The Last of the Mohicans. In 1990 there were about 1,000 Mohegan in the United States; they gained federal recognition as a tribe in 1994. In 1996 the tribe opened a casino and resort on its reservation in Montville, Ct.

Monica Street - Monica Street was named after Saint Monica, born of Christian parents at Tagaste, North Africa, in 333. She died at Ostia, near Rome, in 387 and became a saint because of her acts of loyalty to God during times of suffering.

Monroe Street/Drive - Monroe Street was named for President Monroe, elected in 1816 and 1820. The street was named shortly after his term in office. He earned respect throughout many of the states during his presidency. As a youthful politician, he joined the anti-Federalists in the Virginia Convention, which ratified the Constitution, and in 1790, he was elected United States Senator. He was the Minister to France from 1794-1796 and displayed strong sympathies for the French cause. Later, he helped negotiate the Louisiana Purchase with Robert R. Livingston. His ambition and energy, together with the backing of President Madison, made him the Republican choice for the Presidency in 1816. With little Federalist opposition, he easily won re-election in 1820. Monroe made unusually strong Cabinet choices, naming a Southerner, John C. Calhoun, as Secretary of War, and a northerner, John Quincy Adams, as Secretary of State. Only Henry Clay's refusal kept Monroe from adding an outstanding Westerner. Early in his administration, Monroe undertook a goodwill tour. At Boston, his visit was hailed as the beginning of an "Era of Good Feelings." Unfortunately these "good feelings" did not endure, although Monroe, his popularity undiminished, followed nationalist policies. Across the facade of nationalism, ugly sectional cracks appeared. A painful economic depression undoubtedly increased the dismay of the people of the Missouri Territory in 1819 when their application for admission to the Union as a slave state failed. An amended bill for gradually eliminating slavery in Missouri precipitated two years of bitter debate in Congress. The Missouri Compromise bill resolved the struggle, pairing Missouri as a slave state with Maine, a free state, and barring slavery north and west of Missouri forever. In foreign affairs Monroe proclaimed the fundamental policy that bears his name, responding to the threat that the more conservative governments in Europe might try to aid Spain in winning back her former Latin American colonies. Monroe did not begin formally to recognize the young sister republics until 1822, after ascertaining that Congress would vote appropriations for diplomatic missions. He and Secretary of State John Quincy Adams wished to avoid trouble with Spain until it had ceded the Floridas, as was done in 1821. Great Britain, with its powerful navy, also opposed reconquest of Latin America and suggested that the United States join in proclaiming "hands off." Ex-Presidents Jefferson and Madison counseled Monroe to accept the offer, but Secretary Adams advised, "It would be more candid ... to avow our principles explicitly to Russia and France, than to come in as a cock-boat in the wake of the British man-of-war." Monroe accepted Adams's advice. Not only must Latin America be left alone, he warned, but also Russia must not encroach southward on the Pacific coast. ". . . the American continents," he stated, "by the free and independent condition which they have assumed and maintain, are henceforth not to be considered as subjects for future colonization by any European Power." Some 20 years after Monroe died in 1831, this became known as the Monroe Doctrine.

Monterey Avenue - A monastery in California during the Great Depression provided the inspiration for the name Monterey Avenue.

The city (1991 pop. 120,651), is located in Lombardy, N Italy. Manufactures of this highly diversified industrial center include felt hats, carpets, textiles, glass, plastics, and machinery. The history of Monza is closely related to that of Milan. The cathedral, founded (6th cent.) by the Lombard queen Theodolinda, contains the iron crown of Lombardy, which was made, according to tradition, from a nail of Christ's cross and which was used to crown Charlemagne, Charles V, Napoleon I, and other emperors as kings of Lombardy or of Italy.

Mount Vernon Street
- Mount Vernon Street was named after Mont Vernon, located in New Hampshire near Nashua, New Hampshire. Mont Vernon is a town located in Hillsborough County, New Hampshire. As of the 2000 census, it had a population of 2,034. It is not entirely clear why it is spelled differently than the many other towns in the United States named after Mount Vernon, the home of George Washington. Some say the "u" in "Mount" was accidentally dropped by a town clerk filling out official papers, and others say the change was made deliberately to distinguish the town as a tourist destination. As late as the early 1900s, there was some dispute about how to spell the name.

Mulberry Street
- Mulberry Street is the common name for the Moraceae, a family of deciduous or evergreen trees and shrubs, often climbing, mostly of pantropical distribution, and characterized by milky sap.

Musket Drive - Musket Drive was named for muskets, which revolutionized fighting style and warfare, taking away hand to hand combat and changing it to something most view as a horrid destructive and counter productive. A musket is a muzzle-loaded, smooth-bore long gun. Its user fires from the shoulder, except in the case of the rare wall guns. The date of the origin of muskets remains unknown, but they are mentioned as early as the late 14th century. Muskets became obsolete by the middle of the 19th century, as rifles superseded them. Typical musket calibers ranged from .50 to .75 inches. A soldier primarily armed with a musket had the designation of a musketman or of a musketeer. As bullets, muskets used spherical lead balls packed in a paper cartridge which also held the black powder (gunpowder) propellant. The balls, slightly smaller than the bore, came wrapped in a loosely-fitting paper patch which formed the upper part of the cartridge.

Myrtle Street - Myrtle Street was named Myrtle, whose common name is Myrtaceae, a family of shrubs and trees almost entirely of tropical regions, especially in America and Australia. The family is characterized by leaves (usually evergreen) containing aromatic volatile oils. Many have showy blossoms. Although of lesser importance in the United States, the family is of considerable economic value throughout the world for timber, gums and resins, oils, spices, and edible fruits. The true myrtle genus (Myrtus) is predominantly of the American tropics, but the classical myrtle (M. communis) is native to the Mediterranean area. It is a strongly scented bush whose glossy leaves and blue-black berries were made into wreaths for victors in the ancient Olympic games. (In America several unrelated plants are also called myrtles, e.g., the sand myrtle of the heath family, the periwinkles of the dogbane family, and several species of the bayberry family.) Among the many trees of the myrtle family yielding edible fruit, only the guava (genus Psidium), native to tropical America, is grown commercially in the United States. The most important spice plants of the family are the clove tree (Syzygium aromaticum or Eugenia caryophyllata), native to the Moluccas and the Spice Islands, and the tropical American Pimenta genus that includes the pimento or allspice (P. officinalis or dioica) and the bay rum tree (P. racemosa), source of an oil used as an ingredient of bay rum. Eucalyptus, a large genus of evergreen shrubs and trees, is a characteristic component of the flora in its native Australia, where it is the leafy haunt and sole food source of the koala, often associated with it in story. Among its many common names are ironbark, bloodwood, and gum tree (a name also applied to many unrelated trees). Numerous species, especially the Tasmanian blue gum (E. globulus), are now naturalized in the W United States and have become the distinctive vegetation of many California areas that were previously treeless. In Australia several species are among the tallest trees known, e.g., E. regnans, which reaches a height of over 300 ft (91 m). Eucalyptus trees are a valuable source of timber, of kinos (a resinous substance used in medicines and tanning), and of eucalyptol and other essential and medicinal oils. Some hardwood members of the myrtle family are among the many trees known as ironwood, e.g., Eugenia confusa, of Florida and tropical America. The myrtle family is classified in the division Magnoliophyta, class Magnoliopsida, order Myrtales.
