Answer:
British mathematician William Bourne made some of the earliest known plans for a submarine around 1578, but the world’s first working prototype was built in the 17th century by Cornelius Drebbel, a Dutch polymath and inventor in the employ of the British King James I. Drebbel’s sub was probably a modified rowboat coated in greased leather and manned by a team of oarsmen. Sometime around 1620, he used it to dive 15 feet beneath the River Thames during a demonstration witnessed by King James and thousands of astonished Londoners. Unfortunately, none of Drebbel’s plans or engineering drawings has survived to today, so historians can only guess about how his “diving boat” actually operated. Some accounts say it submerged via a collection of bladders or wooden ballast tanks, while others suggest that a sloping bow and a system of weights were used to propel the boat underwater when it was rowed at full speed.

Panese Feudal System
Just like England in Medieval times, Japan also had a feudal system. It was structured very similarly to the English setup with a few changes of names and positions. The most powerful positions in society were the Emperor, Shogun, Daimyo and Samurai. Although these 4 positions were the most powerful in Japan at the time, they made up only roughly 10% of the total population, while roughly 90% were peasants and below.
Picture
The Emperor was looked up to by all of his people as the supreme ruler but held little political power and was seen as more of a 'puppet figure'.
The Shogun was probably the most important figure in Japanese society. He was seen as 'second in line' but did the most work. He was a military leader, so he was in charge of many of decisions to do with their armies, battles etc..
The Daimyo was a very powerful figure who served the shogun. His job control a large area of land. He was also in charge of their samurai, whom he paid to work and protect him.
The Samurai were Japanese warriors (similar to the European knight). They served and protected their Daimyo with respect. They also fought for their people and protected them, bringing justice and order to the community. Their followed a code of conduct called Bushido, meaning 'Way of the warrior' which told them how to live their lives.
Ronins were samurai warriors who had either been 'expelled' from their allegiance or their daimyo had died.
Peasants were farmers and fishermen. They were actually considered a higher class in Medieval Japan than in Medieval England because the Japanese believed that the peasants produced food, which was depended on by all classes, therefore, they worked harder.
Artisans were workers skilled in a particular trade. These included: sword-maker, dressmaker, woodblock print making etc.
Merchants were considered the lowest class in Medieval Japan unlike Medieval England. Their job was to trade/sell goods and shop-keep.
