What events lead to the establishment of St. Augustine and Ft. Caroline in North America?

I think it was because evry European country was trying to expand.

Spain colonies came to St.Augustine, which is why it is a spanish city and was the first city in the USA. European settlers came to Ft.Caroline for the same purpose basically.

nothing certain is known about what happened, but it seems that the country declined gradually, perhaps due to bad government, or, more likely, due to a series of bad harvests, which resulted in widespread and recurrent famine.
