Manifest Destiny.
It's the same reason the United States spread from wherever the hell Columbus landed to the other side of the country.

Columbus found the Americas, but had nothing to do with the United States.
The British sent colonists here, Puritans that were in search of religious freedom. After so long the colonists rebelled, and a war with the might of the British war machine ensued.
The colonists used tactics that were not gentlemanly for the time, because the British slapped them in 60yd stacked line formation musket fights.
After so long the French came and trained many of the colonists up to fight in a more gentlemanly manner (brutal 60 yard musket vollies)
I think the British just got sick of it and left. The colonists were getting better at stacked line formation musket battles, but they continued the other tactics as well.
I think Columbus sailed for Spain, and they laid claim to South America.
