The Triple Entente, also known as the Allied Powers, was an alliance formed during World War I. The three countries that made up the Triple Entente were:
Russia: The Russian Empire, led by Tsar Nicholas II, was one of the founding members of the Triple Entente. Russia joined the alliance to counter the growing influence of Germany and Austria-Hungary in Europe.
France: The French Third Republic was another key member of the Triple Entente. France had a longstanding rivalry with Germany and sought alliances to protect itself from potential German aggression.
United Kingdom: The United Kingdom, specifically England and Wales, along with its dominions and colonies, was the third member of the Triple Entente. The British Empire, under the leadership of King George V, joined the alliance to preserve the balance of power in Europe and protect its interests.
It's worth noting that the Triple Entente expanded during the war, with additional countries such as Italy, Japan, and the United States joining the alliance at various points.
