Porcmade from rare and valuable materialselain (/ˈpɔːrsəlɪn/) is a ceramic material made by heating materials, generally including kaolin, in a kiln to temperatures between 1,200 and 1,400 °C (2,200 and 2,600 °F). The toughness, strength, and translucence of porcelain, relative to other types of pottery, arises mainly from vitrification and the formation of the mineral mullite within the body at these high temperatures. Though definitions vary, porcelain can be divided into three main categories: hard-paste, soft-pasteand bone china. The category that an object belongs to depends on the composition of the paste used to make the body of the porcelain object and the firing conditions.
Porcelain slowly evolved in China and was finally achieved (depending on the definition used) at some point about 2,000 to 1,200 years ago, then slowly spread to other East Asian countries, and finally Europe and the rest of the world. Its manufacturing process is more demanding than that for earthenwareand stoneware, the two other main types of pottery, and it has usually been regarded as the most prestigious type of pottery for its delicacy, strength, and its white colour. It combines well with both glazes and paint, and can be modelled very well, allowing a huge range of decorative treatments in tablewares, vessels and figurines. It also has many uses in technology and industry.
The Romans would develop road systems as they went along with their expansion. Every time they'd conquest new territory, they'd make sure to keep the new colonies controlled by facilitating access to them through the construction of new roads. In addition, the development of these routes was crucial to containing attacks and ensuring a successful defense of the Empire, as the armies would move move faster and arrive quickly to the territories in conflict.
This strategic emphasis in roads and bridges was vital to the success of their army. The routes were built specifically with speed of movement in mind, designing them mostly in straight lines for efficiency.

while the Middle colonies and New England had few slaves. Most northern
immigrants were in the middle class, while most southerners were poor men

Propaganda is used to try to make people think a certain way. Stories about bad things the Germans had done were told to make people angry and frightened so everyone would want Britain to beat them in the war.
