Existing at a time when powerful empires controlled the world, the Han
Empire is one of the most powerful and influential empires this world has
ever know. With its relatively quick expansion, and other essential factors,
such as the great wall and the Silk Road, Han was able to advance militarily,
economically, and technologically with little threat of invasion by foreign
invaders. The Han has also made major contributions to the way we live
today, being responsible for the development of paper, the wheelbarrow,
and the simplest form of modern seismography.
