The Spread of Factories The War of 1812 provided a boost to American industries. The British blockade cut Americans off from their supply of foreign goods.

To profit from the efficiency provided by manufacturing, they built more factories. As American investors took advantage of new technologies and built more factories, the American economy grew.
