What started the First Seminole War in 1817?

The First Seminole War (1817–18) began over attempts by U.S. authorities to recapture runaway black slaves living among Seminole bands. Under General Andrew Jackson, U.S. military forces invaded the area, scattering the villagers, burning their towns, and seizing Spanish-held Pensacola and St. Marks.

Explanation:

When a government worker stole from a Seminole garden and burned crops, the war started. ... In 1817 in South Georgia, Seminoles became angry because colonists were trespassing on their hunting grounds.

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.
