    China’s early historical development long predated Japan’s and Korea’s, which is why a chapter on East Asian history logically begins in the second millennium BCE with China’s first dynasty. However, today’s nation of China is much larger than China was in ancient times. In earlier times, the bulk of the Chinese population lived in China proper, by which we mean the historical heartland of ancient China (see Map \(\PageIndex{1}\)). To the east, China proper is bounded by the Yellow Sea, East China Sea, and South China Sea. To the south, it is bordered by the mountainous jungles of Southeast Asia. To the west and north, China is rimmed by a transitional frontier zone where land suited to agriculture gives way to mountains and plateau or vast expanses of steppe grasslands and desert. At times, the dynasties of China became actively involved in all of these neighboring areas, incorporating them directly into their expanding empires or indirectly as subordinate, tribute-paying states. Those areas include parts of the Korean Peninsula, Northeast China, Mongolia, Central Asia, and Vietnam.

    Within China proper, two rivers were particularly important to the formation of agricultural communities that served as the building blocks of Chinese civilization. Those were the Yellow River and Yangzi River. The Yellow River meanders through the northern half of China, where a cool, dry climate is well-suited to wheat and millet farming. Beginning far to the west, this river meanders over dusty plateau, becomes muddied with silt, and then deposits this sediment along its middle and lower reaches. The plains surrounding these reaches are collectively referred to as the North China Plain. Historically, this was the heartland of Chinese civilization. However, the Yangzi River was just as important. Located in south China where the weather is relatively warmer and wetter, its long basin provided fertile soil for rice-paddy agriculture. Over time, the early dynasties expanded into and included the settled agricultural communities in this region.

    Japan is an island country consisting of four main islands and many smaller ones located off the Pacific coast of the Asian continent. At 400,000 square kilometers, Japan is slightly smaller than California, although the terrain is more rugged. Because Japan is covered by mountains and traversed by numerous rivers, only fifteen percent of the land is suited to agriculture. Much of that was concentrated in two plains–the Kinai Plain and Kanto Plain–making them particularly important to Japan’s early history. Japan is also located along the Pacific Ring of Fire, where tectonic plates composing the earth’s crust frequently move and collide. That is why earthquakes and volcanic activity have been a constant threat to populations living on these islands.

    The Korean Peninsula is the location of North and South Korea today. Prior to the twentieth century, however, it saw a long succession of Korean kingdoms. Extending roughly 1100 kilometers southward from the Asian landmass, the peninsula is bounded by seas to the east, west, and south, and defined by the Yalu River to the north. Beyond that lies Northeast China which was only periodically included in the territory of Chinese empires. Consequently, because the peninsula lies between China to the north and west and Japan to the east, Korean dynasties have been deeply impacted by these states’ histories and cultures. Like Japan, Korea is also mountainous, although coastal areas and plains located to the west and south were well-suited to agriculture.

    The countries of East Asia share in the region’s temperate climate and summer monsoon season. During the summer months, warm and moist air originating from the Pacific flows from southeast to northwest, while during the winter months cold and dry air originating from Central Asia moves in the opposite direction. Thus, those areas of East Asia located further to the east and south are generally warmer and wetter, and for longer periods of time. That made them well-suited to rice-paddy agriculture, and rice consequently became the primary cereal crop in southern China, the Korean peninsula, and the islands of Japan. While growing rice is labor intensive, this grain also offers high yields per unit of land, so it has supported population growth in these countries and, therefore, the formation of vibrant civilizations.
