Эссекибо
In 1648 Spain signed the Peace of Münster with the Dutch Republic, whereby Spain recognized the Republic's independence and also small Dutch possessions located east of the Essequibo River, which had been founded by the Dutch Republic before it was recognised by Spain. However, few decades after the Peace of Münster, the Dutch began to spread gradually west of the Essequibo River, inside the Spanish Guayana Province. These new settlements were regularly contested and destroyed by the Spanish authorities.
