John Brown was a radical abolitionist who believed in the violent overthrow of the slavery system. During the Bleeding Kansas conflicts, Brown and his sons led attacks on pro-slavery residents. Justifying his actions as the will of God, Brown soon became a hero in the eyes of Northern extremists and was quick to capitalize on his growing reputation. By early 1858, he had succeeded in enlisting a small “army” of insurrectionists whose mission was to foment rebellion among the slaves. In 1859, Brown and 21 of his followers attacked and occupied the federal arsenal in Harpers Ferry. Their goal was to capture supplies and use them to arm a slave rebellion. Brown was captured during the raid and later hanged, but not before becoming an anti-slavery icon.
Columbus managed to convince "The Enterprise of the Indies" to (put what he convinced them to do here), but not King John ll of Portugal. You can also switch the order for that sentence (Columbus wasn't able to convince King John ll of Portugal, but he was successful with "The Enterprise of the Indies"). (enter name here)'s wife Felipa dies (either enter cause of death or why it relates to the previous sentence here). Hope this helps

He escaped France because religious tensions grew too high for him to stay there safely.
