Who were the main people of "feudal" life?

The main people of "feudal" life as ruling would be the king/monarch to knights/vassals. If you mean normally. It would be nobles or serfs. Mainly serfs, servants and villeins.

Hope this helps.

president jefferson protested this interference in american trade. he sent james monroe to london to negotiate a treaty. jefferson wanted britain to stop taking sailors from american ships, and to stop interfering in the trade of neutral nations. monroe tried many times to discuss such an agreement. but the british foreign minister was always too busy to see him.

explanation:

map scale refers to the relationship (or ratio) between distance on a map and the corresponding distance on the ground. for example, on a 1: 100000 scale map, 1cm on the map equals 1km on the ground.
