Koreans are the people who have long history. People say that ancient Korean originated from Mongolia, as the time went on, people from a little villages started to movie down. As they grew bigger they formed a little city and made a leader. From than on they started to expand faster and faster taking territories from different areas. When they reached the bottom of Korea they realized that they are surrounded by water and only way to go was up. That was when they started to grow their power. For a while, they were one united country, until the government became corrupted and split in to three different nations. After many years of battle, one king reunites the whole kingdom but than again they split in to three nations. Then again this nation comes back together. Their main food sources came from hunting and growing crops. They also ate lots of vegetables and chickens. They had their medicine from their own uses of special crops, plants, different kind of animal's parts and insects. Korean architecture was very beautiful. When they were building a kings kingdom or a temple they used no steels but just wood, and they still made it weatherproof and waterproof. Rich people with some stats in the country had a nice building that is only built out of wood too, but for people who don't have money or states, they used different materials. They build the side of the wall with a segment and some wood, floor mad up of segment, but the roof is made up of hay and mud. It was still weatherproof and waterproof but they had to make a new roof every year.
Mayans in the other hand they don't have any record of how they came to where they were but they start their own civilizations
