Spoiler : I bought (I don't remember order) 4 settlers, a scout, a shrine, a worker (toledo, Cordoba's was stolen from morocco). Obviously, not all of the gold was from NWs. GBR city was city #3 but it was where I sent my first settler (I kind of cheated ). I have DoFs with several civs. I'm pretty sure I got my first one after getting reckless expansion, but it was with Gandhi. Then I managed to get a few more, most likely due to mutual friend bonuses.
