The Sweat

The sweating sickness was a mysterious plague like sickness that struck in England beginning in 1485. Lasting until 1551, after which vanished. The symtoms were dramatic and sudden, and you would die within hours. The cause is still unknown to this day.
If you looked at it politicly- The first Sweat was during the reign of Henry VII. Henry VII's own son Arthur died of the Sweat, around age 16.
The Sweat seemed to like children or teenagers, like the two brothers that died within hours of each other. The brothers were Henry and Charles Brandon, the 2nd and 3rd Dukes of Suffolk. They ran to Huntingdon, Huntingdonshire, in an effort to ecscape the epidemic, but instead they both wound up dying. Henry supposedly died first, next his younger brother Charles.
Many people feared the Sweat and tried to run from it, only leading right into it. The sickness hit the English Court many times, no one knowing how or where it had come from. Those who had died from it, didn't know where they got it from, but historians today suppose that the sickness came from the War of The Roses, where all the sewage and unhealthy enviroment meet the first victim of the Sweat.
A similar sickness ocurred in France around 1715, but the symtoms included a rash which was not like the Sweat.
People today have no idea where the Sweat came from or how it left.
