Why were the “Tolpuddle Martyrs” so called?
lana66690 [7]

Answer:

Their name does come from the Dorsetshire village of Tolpuddle, the place where the six farm workers were reported by a landowner of maintaining a secret connection with the union called Friendly Society of Agricultural Labourers. They are also called martyrs because their imprisonment made them popular heroes believed to have suffered by a just cause. They spent two years in an Australian jail before being released in 1837.

Explanation:

A martyr is someone who dies for a cause, and even though these men didn´t die, they did suffer greatly and became a symbol of the workers´ struggles.
