> From the time they first arrived seeking a haven from persecution, Curaçao's small, Jewish community has had an extraordinary impact on the island's economy, politics and culture. The first permanent Jewish settlers, seventy
> Sephardim of Portuguese descent, arrived in 1659. Relations with the local Dutch Protestant elite were good, and no laws limited Jews in their work or residences. They became highly successful in trade and shipping.
>
> In the 20th century, other Ashkenazi Jewish immigrants worked their way up the economic ladder after having started out as peddlers and small-scale merchants.

> The Amerindian Arawaks were the 1st inhabitants of Curaçao, before the Spanish lieutenant Alonso de Ojeda visited our island in 1499.
>
> In 1634, long after the Spanish had abandoned Curaçao, the Dutch West Indies Company claimed the island. In 1642, Peter Stuyvesant was installed as governor. Curaçao soon became a Dutch commercial center and developed
> extensive slave trade activities. During this period, the local language Papiamentu-a mixture of Portuguese, Spanish, Dutch, and African dialects, developed
> by the slaves-became the main means of communication. Peter Stuyvesant left Curaçao in
> 1647 to become Governor of New Amsterdam, later to become New York City.
>
> Soon after, Jewish families from Holland, other parts of Europe, and Asia settled in Curaçao-with the total population reaching 2,000 by the early 1700s.
> In 1732, the community created the Mikve Israel-Emanuel Synagogue in Willemstad, the oldest still functioning synagogue in the Western Hemisphere.
>
> With the discovery of oil in 1914, at Lake Maracaibo in Venezuela, the Caribbean Petroleum Company decided to build a refinery on Curaçao. It became operative in May 1918. The 440 ha. refinery at Schottegat was later
> acquired in the 1960s in hands by Shell Curaçao N.V. and at one time employed 25,000 people from all over the world.
