Guy Fawkes and the Gunpowder Plot

Every year in Britain, we have fireworks and a bonfire. It's all about a man called Guy Fawkes also known as Guido.

How the Plot started

The plan was that they should blow up Parliament and the king.They dug a hole but they found a cellar so they put 36 barrels of gunpowder .  

Why was a letter sent to lord Monteagle?

Francis Tresham sent a letter to lord Monteagle that was a warning that he should not go to parliament so he won't get blown up!
