Territorial
rivalries became more intense as the settlements of both countries
expanded. The British and French could not agree on the boundaries of
Acadia.
Disputes also arose over the Great Lakes region and the land around
lakes George and Champlain. Most important, both countries claimed
the vast area between the Allegheny
Mountains and the Mississippi River. In 1749, the French explorer de
Bienville traveled through the Ohio River
Valley to reinforce
France's claim there. The first Ohio Company sent Christopher Gist to
survey the same area in 1750. In 1753 the French built a
chain of forts along the Allegheny River in
Pennsylvania. Lieutenant Governor Robert Dinwiddie of Virginia sent
George Washington to the commander
of the new forts, protesting
against French occupation of the area. But the French refused to leave.
In 1754, Washington led a small force of colonial
troops to force the French to withdraw. They were
attacked and defeated near Fort Duquesne, now Pittsburgh, in the war's
first battle. Meanwhile,
representatives of seven colonies met
in Albany, New York, to plan military action.
The Marquis de
Montclam took over the leadership of the French forces in 1756. He led
attacks on Fort Oswego and Fort William Henry. The
French troops outfought the British and
seized both these forts. William Pitt became the political leader of
Great Britain in the same year. His
leadership gave new life to the British cause, which
had been waning. In
1759, the British took the city of Quebec after a short but decisive
battle.
This marked the real end of the war,
although the struggle held out until Montreal was taken a year later.
By the terms of the Treaty of Paris, signed in
1763, Great Britain
received Canada and most French
possessions east of the Mississippi River. The Spanish territory of
Florida also went to Great
Britain. Spain received all French land west of the
Mississippi. France's great
American empire was reduced to two islands south of Newfoundland
and
two islands in the Caribbean. Spain was the only
real rival of the British.
