Why in the treaty of Paris in 1763?

France had secretly handed over what they had east of the Mississippi to Spain under the 1762 Treaty of Fontainbleau to avoid such a situation.

However,British Prime Minister Lord Bute wanted a peace that was not so harsh that France would want revenge,and start another war as soon as the opportunity arose - losing the Seven Years War had weakened France,but it was still THE major continental European power.Additionally,Bute thought that the territory Britain took anyway under the treaty might be too much to digest in terms of administration and control - taking even more would make this problem worse.

The treaty of Paris in 1763 ended the French and Indian war which had started in 1754... George Washington was involved in the first battle where Jumonville was killed by the Indian "Half King"

Most fighting ended in 1759 when Gen James Wolfe died but won the battle of Quebec. The French commander, Montcalm also died in battle.

The war was brought to an end in 1763 when Sir Jeffrey Amherst captured Montreal which ended all French rule

There is give and take,by both sides,when negotiating.

win some,lose some.
