They hampered technological development.

They promoted economic growth.

They brought renewed conflict with Britain.

Answer 1

If you are talking about them trying to expand in to present-day Canada, then it brought renewed conflict with Britain (war of 1812)
if it is towards the west, i guess it hampered technological development, because most people were moving west through the trails, instead of staying to help build up the economy

hope this helps
