England (of course) !!!!!!!
John Adams was the second president of the U.S.
Well they both fought each other . Thats a similar share.
I would say that Christopher Columbus was influenced by the travels of Marco Polo.
He was greatly inspired by his travels and wanted to become as famous as Polo was as an explorer, and eventually, he did follow in his footsteps. Polo's travels changed the European perception of the Asian world, and as you know, Columbus also wanted to go to Asia, but he ended up in America.
6 million Jews were killed in all and for extra he killed 17 million people overall in the Holocaust.
