What obstacles did christopher columbus face in making his dream of exploration a reality

He had nine ships sink and harsh weather and violent

people.Who had many diseases and had a lack of food and water. So many people died on the ship.They ate saw dust from wood boards because they ran out of food.They were always dehydrated. Christopher Columbus faced mutiny.

His crew wanted to kill him and wanted to turn back around in the boat. The boat started to fall apart on his first voyage but it quickly got fixed up.He did not have a map.

Christopher Columbus faced getting thrown

in jail after his second journey cause King Ferdinand and Queen Isabella were ungrateful

even though he had found so many islands. His

crew members wanted to head back to Spain, but

Christopher Columbus didn't want to go back.
