Abū ‘Abd Allāh Muḥammad ibn ‘Abd Allāh al-Lawātī al-Ţanjī ibn Baṭūṭah (Arabic: أبو عبد الله محمد بن عبد الله اللواتي الطنجي بن بطوطة‎), or simply Ibn Battuta (ابن بطوطة), also known as Shams ad-Din (February 25, 1304–1368 or 1369), was a Berber Muslim Moroccan explorer, known for his extensive travels, accounts of which were published in the Rihla (lit. "Journey"). Over a period of thirty years, he visited most of the known Islamic world as well as many non-Muslim lands; his journeys including trips to North Africa, the Horn of Africa, West Africa, Southern Europe and Eastern Europe in the West, and to the Middle East, South Asia, Central Asia, Southeast Asia and China in the East, a distance surpassing threefold his near-contemporary Marco Polo. Ibn Battuta is considered one of the greatest travellers of all time. He journeyed more than 75,000 miles (121,000 km), a figure unsurpassed by any individual explorer until the coming of the Steam Age some 450 years later.

All that is known about Ibn Battuta's life comes from the autobiographical information included in the account of his travels. Ibn Battuta was born into a Berber family of Islamic legal scholars in Tangier, Morocco, on 25 February 1304, during the reign of the Marinid dynasty. As a young man he would have studied at a Sunni Maliki madh'hab, (Islamic jurisprudence school), the dominant form of education in North Africa at that time. In June 1325, at the age of twenty-one, Ibn Battuta set off from his hometown on a hajj, or pilgrimage, to Mecca, a journey that would take sixteen months. He would not see Morocco again for twenty-four years.

"The Man" is a slang phrase that may refer to the government or to some other authority in a position of power. In addition to this derogatory connotation, it may also serve as a term of respect and praise.

The phrase "the Man is keeping me down" is commonly used to describe oppression. The phrase "stick it to the Man" encourages resistance to authority, and essentially means "fight back" or "resist", either openly or via sabotage.

The earliest recorded use^{[citation needed]} of the term "the Man" in the American sense dates back to a letter written by a young Alexander Hamilton in September 1772, when he was 15. In a letter to his father James Hamilton, published in the Royal Dutch-American Gazette, he described the response of the Dutch governor of St. Croix to a hurricane that raked that island on August 31, 1772. "Our General has issued several very salutary and humane regulations and both in his publick and private measures, has shewn himself the Man." ^{[dubious – discuss]} In the Southern U.S. states, the phrase came to be applied to any man or any group in a position of authority, or to authority in the abstract. From about the 1950s the phrase was also an underworld code word for police, the warden of a prison or other law enforcement or penal authorities.

Marco Polo (ⁱ/ˈmɑrkoʊ ˈpoʊloʊ/; Italian pronunciation: [ˈmarko ˈpɔːlo]; c. 1254 – January 9, 1324) was a Venetian merchant traveler from the Venetian Republic whose travels are recorded in Il Milione, a book which did much to introduce Europeans to Central Asia and China. He learned about trading whilst his father and uncle, Niccolò and Maffeo, travelled through Asia and apparently met Kublai Khan. In 1269, they returned to Venice to meet Marco for the first time. The three of them embarked on an epic journey to Asia, returning after 24 years to find Venice at war with Genoa; Marco was imprisoned, and dictated his stories to a cellmate. He was released in 1299, became a wealthy merchant, married and had three children. He died in 1324, and was buried in San Lorenzo.

Their pioneering journey inspired Christopher Columbus and others. Marco Polo's other legacies include Venice Marco Polo Airport, the Marco Polo sheep, and several books and films. He also had an influence on European cartography, leading to the introduction of the Fra Mauro map.
