The delegates to the Constitutional Convention finally agreed the Three Fifths Compromise, that slaves should be counted at three fifths of their real number.
The first Continental Congress had gathered to discuss the Coercive Acts, but the Americans had called them the Intolerable Acts. It was British's way to punish Boston after the Boston Tea Party where men dressed as Native Americans dumped British tea into Boston harbor because of its tax.
The countries that attended the conference were: Austria-Hungary, Belgium, Denmark, France, the German Empire, Italy, Netherlands, the Ottoman Empire, Portugal, the Russian Empire, Spain, Sweden-Norway, the United Kingdom, and the United States of America who had a special right to accept or decline the terms of the deal and the participation in the deal.
The effects of the conference were mostly in regards to the African Continent. They wanted to find a way to spread their empires and gain strength while not fighting each other, so they decided to cut Africa up into smaller pieces and divide it among themselves. The result was that 90% of African territory was taken by various European powers.
