Trade and exchange of ideas with neighbouring nations is one of the means by which civilizations advance and evolve. This happened widely among the ancient peoples living in lands bordering the Mediterranean Sea, as well as in India, China and other Southeast Asian nations.
The idea of Freedom and Freedom from Religious persecution may have been cultivated and promoted by Piarates:
Edward Kritzler tells the tale of an unlikely group of swashbuckling Jews who ransacked the high seas in the aftermath of the Spanish Inquisition. At the end of the fifteenth century, many Jews had to flee Spain and Portugal. The most adventurous among them took to the seas as freewheeling outlaws. In ships bearing names such as the Prophet Samuel, Queen Esther, and Shield of Abraham, they attacked and plundered the Spanish fleet while forming alliances with other European powers to ensure the safety of Jews living in hiding. Filled with high-sea adventures–including encounters with Captain Morgan and other legendary pirates–Jewish Pirates of the Caribbean reveals a hidden chapter in Jewish history as well as the cruelty, terror, and greed that flourished during the Age of Discovery.
