Lord Mayor Thomas Bloodworth
Many people blamed Bloodworth for the decisions he took for stopping the fire. He waited for three days to take action and to stop the fire because he was worried about how much the cost for reparations were going to be. Many people believe that if he took action before the fire spread then their homes and memories would have been saved from destruction and they would have avoided this crisis.
French and the Dutch
Also, the French and the Dutch were blamed for the fire because of how convenient they entered the city of London as the fire continued to blaze on simultaneously. The two nations had difficulties and past arguments with each other. So, for the city to see them together and friendly with one another, they suspected something odd, especially with the fire going on.
Roman Catholics
The Roman Catholics were being accused of starting the fire because many people already had a negative view towards the Roman Catholics Many people began to draw their own conclusions. People believe that they might have triggered the fire because the religion is strongly linked with Spain and France, two of England's major enemies. There was also speculation about the priest, many people believed that they had cruel ways. The speculation was based off of stereotypes and observations that lead to conclusions.
Protestants
Along with Bloodworth, the French and the Dutch and the Roman Catholics, the protestants were are blamed for starting the fire. Many people were already angry before the fire started. The Bubonic Plague was going around and nothing could stop it from killing the people closest to them. Poverty has always been a problem, so when you mix both of these reasons, along with many more, you get a massive amount of tension. Speculation stirred that the protestants might have caused the fire as a way to seek vengeance.
