How did various european countries become involved in the outcome of the american revolution?

The American people vs. the empirilist British but just not the American people but french, Dutch and Spanish too. Without them without a dought the American would have no change, because it's the European who trained, supplied and fight alongside the Americans.
After the American revolution European countries had to deal with revolutionist and rebels.

I hope I was a help.
