weapons on the crusade
The Mangonel was a king of catapult that could launch projectiles across long distances.Attackers became very creative with what they launches because they could cause a lot of panic inside the castle walls. They might throw stones, sharp wooden pole, burning tar or dead bodies. The idea was to cause fire or disease within the castle walls, forcing the inhabitants outside The advantage of this catapult was that it was very light and its ability to throw rock and fire. The major disadvantage was that it was not that accurate. The range was determined by the weight of the projectile and the strength of the mangonel. In order to get the catapult into effective range of a castle, it would have to come into range of the castle's defenders.

the Battering Ram was used to literally batter, pound, punch and shake down gates, doors and walls of Medieval castles, fortresses and towns. Huge tree trunks were used to construct a battering ram and were often fitter with a metal head and supported by metal bands. The ram was swung back and forth by a team of men. One of the weaknesses of the battering ram was the fact that it had to be brought right up to the castle door or wall which made the attackers vulnerable.

The trebuchet was the largest and most formidable of the siege machines and was, in essence, a huge catapult.
The trebuchet was used to hurl huge missiles to breach the castle walls. Large rocks and stones were the main ammunition used as they were hurled with force against the walls. Although trebuchets have greater power and range than catapults, they also have drawbacks. Trebuchets are more complicated than torsion catapults and therefore are plagued by mechanical breakdowns, require more maintenance, more skill to operate and a larger crew.

The ballista was a giant crossbow that fired long heavy arrows and was one of the most effective Medieval weapons. They were used to demolish the castle walls and kill the defenders. It was also a weapon of defence. The pros of the Ballista was that it was much more easier to carry around, and could be managed by less people. The cons about the Ballista was that it was made more for throwing arrow type missiles, and didnt throw things as far.

The Black Death
The Black Death was a bubonic plague pandemic occurring in Afro-Eurasia from 1346 to 1353. It is the most fatal pandemic recorded in human history, causing the death of 75–200 million people in Eurasia and North Africa, peaking in Europe from 1347 to 1351.
When spring arrived, the Italian merchants fled on their ships, unknowingly carrying the Black Death. Carried by the fleas on rats, the plague initially spread to humans near the Black Sea and then outwards to the rest of Europe as a result of people fleeing from one area to another.
Causes: Yersinia pestis spread by fleas
Bubonic plague: Patients develop sudden onset of fever, headache, chills, and weakness and one or more swollen, tender and painful lymph nodes (called buboes). This form usually results from the bite of an infected flea. The bacteria multiply in the lymph node closest to where the bacteria entered the human body.
Some of the cures they tried included: Rubbing onions, herbs or a chopped up snake (if available) on the boils or cutting up a pigeon and rubbing it over an infected body. Drinking vinegar, eating crushed minerals, arsenic, mercury or even ten-year-old treacle!
The Peasants Revolt
Peasants' Revolt, also called Wat Tyler's Rebellion, (1381), first great popular rebellion in English history. Its immediate cause was the imposition of the unpopular poll tax of 1381, which brought to a head the economic discontent that had been growing since the middle of the century.
