MAP

18th century to the present

A reformation of cartography that evolved during the 18th century was characterized by scientific trends and more accurate detail. Monsters, lions, and swash lines disappeared and were replaced by more factual content. Soon the only decorative features were in the cartouche and around the borders. The map interiors contained all the increasing information available, often with explanatory notes and attempts to show the respective reliabilities of some portions.

Where mapmakers formerly had sought quick, profitable output based on information obtained from other maps and reports of travelers and explorers, the new French cartographers were scientists, often men of rank and independent means. For expensive ventures, such as the triangulation of two degrees of a meridian to determine the Earth’s size more accurately, they were subsidized by the king or the French Academy. Similar trends were developing across Europe.

the first historical instance of china engaging in internationalism was during the han dynasty.[1] at the start of the han dynasty, the huns in the north were attacking the frontiers of han and trying to obtain riches. emperor wu of han wanted to gain an alliance with a country called dayuezhi so the two countries could join together and fight against the huns.[2] to obtain this alliance, emperor wu sent zhang qian to the west to establish economic and cultural connections.[2] history records that during the han dynasty there were four primary avenues of contact between china and europe. they included the northern land route, the central land route, the southern sea route, and the far southern sea route.[1] the most famous of these routes is the central land route, or the classical silk road, comprising a network of roads stretching from northwest china to the ports of syria and the black sea, which passed through the oasis of the turkestans and northern persia.[1] the silk road was significant for chinese emperors because it provided dominance over central asia by developing resources and provided new markets for the export of china's most valuable resources.[1]
