NORTH AT THE TOP OF MAPS - POLITICS OR FACTS

Most modern day maps typically show an orientation with the north at the top of two dimensional depiction. In order eras, different directions at the top were more prevalent  and all directions have been used by different societies and culture to depict our world. The biggest factors that contribute to north being commonly placed at the top of a map include the invention of the compass and the understanding of magnetic north and the egocentricity of society, mainly in Europe.

THE COMPASS AND MAGNETIC NORTH

The discovery and use of the compass in Europe in the 1200-1500s may have greatly influenced many modern- day maps with north at the top. A compass points to magnetic north, and Europeans, like other cultures long before, noticed that the earth spins on an axis that is relatively pointed at the north star. That idea combined with the concept that when we look up we stars, contributed to the north being placed at the top of maps, with words and symbols being placed relative to that viewpoints.

EGOCENTRICITY OF SOCIETIES.
Egocentricity is having a view or perceptive that revolves round you or your situation at the center  Thus, in cartography or geography, an egocentric society is one that places itself in either the center of a depiction of the world, or at the top. Information at the top of a map is commonly viewed as being both more visible and more significant.
Since Europe was powerhouse in the world, producing both heavy exploration and printing press - it was instinctual for European mapmakers to put Europe (and Northern Hemisphere) as the focus at the top of maps. Today Europe and North America remain dominant cultural and economic forces, producing and influencing many maps - showing the Northern Hemisphere at the top of the maps.

DIFFERENT ORIENTATIONS.
Most early maps, before the wide-spread use of the compass, placed east at the top. This is generally thought to be due to the fact that the sun rises in the east. It was the most consistent directional maker.

Many cartographers show that they want to be the focus at the top of the map, and therefore, influence the orientation of the map. Many early Arab and Egyptian cartographers placed south at the top of the map because, having most of the world they knew to be the north of them, it drew the most attention to their area. Many early settlers of North America created maps with west-east orientation that resulted from the direction that they primarily traveled and explored. Their own viewpoint greatly altered the orientation of their maps.

in the history of map making, the general rule of the thumb is whoever made the map is probably at the center or the top of it. This rings most true for centuries map making  but has been greatly influenced as well with European cartographer's discovery of compasses and magnetic north
