Did some googling, and came across this article about this Basque Pidgin https://core.ac.uk/reader/230764570. It contains many interesting facts. Including the passage:

"Certain surprising similarities among pidgins and creoles spoken in places distant from each other and with different linguistic components in their formation have led some linguistic to formulate a monogenetic theory that would trace many pidgins and creoles to a common ancestor: A Portuguese based pidgin or even to the Lingua Franca or Sabir spoken in the Mediterranean Basin from the Middle Ages (Whinnom, 1977)."

Even after the middle ages Portuguese seems to be an especially common source of pidgins, found in South east Asia, Africa and the Caribbean (curiously, in now Dutch territories) among other places.
