Klein-Venedig or Welserland was the most significant territory of the German colonization of the Americas, from 1528 to 1546, in which the Welser banking and patrician family of the Free Imperial Cities of Augsburg and Nuremberg obtained colonial rights in the Province of Venezuela in return for debts owed by the Holy Roman Emperor Charles V, who was also King of Spain. In 1528, Charles V issued a charter by which the House of Welser possessed the rights to explore, rule and colonize the area, also with the motivation of searching for the legendary golden city of El Dorado. The venture was led at first by Ambrosius Ehinger, who founded Maracaibo in 1529. After the deaths of Ehinger (1533) and then his successor Georg von Speyer (1540), Philipp von Hutten continued exploration in the interior, and in his absence from the capital of the province, the crown of Spain claimed the right to appoint the governor. On Hutten's return to the capital, Santa Ana de Coro, in 1546, the Spanish governor Juan de Carvajal had von Hutten and Bartholomeus VI. Welser executed. King Charles V revoked Welser's charter.
