Flags are an integral factor in the understanding of a nation's culture as they can often reveal facts about its ideals or population. Colors for instance have, often several, distinct meanings. Red might mean solidarity and connections through blood to some countries whilst to others it might represent power and the blood shed in battle. Aside from their meaning, flags are also very interesting as a piece of art in themselves. The interplay of colors and symbols across their surfaces is considered aesthetically pleasing to some people, and often heart-warming to the residents of that nation. All in all, flags are an aspect of any timeline that should never be ignored.
