It took seven years to complete.

It was the first world war.

On May 1, 1756, France and Austria signed an alliance that was ostensibly defensive – the First Treaty of Versailles. It was recognized that Austria was to remain neutral regarding France's war against Britain, and France was to accept Austria’s attack on Brandenburg-Prussia. Russia joined this alliance – upsetting its traditional hostility towards France. And the new alliance between Madame Pompadour of France, Maria Theresa of Austria and Elizabeth of Russia became known as the League of the Three Petticoats.

In March 1757, Sweden joined the war against Frederick – despite Frederick’s sister being Queen of Sweden. In early May, Frederick's forces began maneuvering against Austria's forces in Bohemia, and on May 5 the two armies met just outside the city of Prague. The fighting lasted two hours, with Frederick losing 11,740 killed and wounded and 1560 as prisoners – about 21 percent of his army's strength. The Austrians lost about as many and retreated behind Prague's walls.

With Frederick surrounded by advancing enemies – Sweden from the north, Russia advancing across East Prussia, and the Austrians coming at him from the south – Britain in 1758 began giving more aid to Frederick. France was focusing on its ground war in America, where it was hoping to stave off defeat while winning in Europe. Britain was hoping to win in America and just hold on in Europe. Austria became distracted by new threats from the Ottoman Empire.

In 1760, the belligerents were again hurting enough from war that they again wanted peace – except for Great Britain. That year the British were tightening their noose around the French in Canada. In October, while Frederick and his army were under pressure in Saxony, a combined force of Russians and Austrians occupied and looted Berlin. Then, hearing that Fredrick and his army were on their way, they fled. Also in October, George II died. The new king, George III, cared little about Hanover, and British subsidies to Frederick were discontinued.

Then Frederick was blessed by good luck. On January 5, Russia's empress, Elizabeth, died. She was succeeded by Peter III, a 33-year-old grandson of Peter the Great on his mother's side, who saw himself as German, disliked Russia and was a great admirer of Frederick. On February 23 he declared an end to the war against Frederick. In Frederick's Brandenburg-Prussia it was seen as a miracle (to be remembered during World War II – the miracle that Goebbels and Hitler had in mind when Franklin Roosevelt died in 1945).

Maria Theresa's Austria was suffering from the loss of Russia as an ally and receiving little help from France, Also, her military was exhausted and she was without money. She saw no hope of defeating Frederick and sent him representatives to discuss an end to the war.

On February 10, 1763, Britain, Spain and France signed the Treaty of Paris, and on February 15, Austria and Brandenburg-Prussia signed the Peace of Hubertusburg.

Frederick had successfully defended his hold on Silesia. Austria had gained nothing. France lost all of its possessions in the Americas to the British – except for some small islands in the Caribbean and on the St. Lawrence River. It also lost its African colony by the Senegal River to the British, and it agreed to pull out of India. The royal French government was also deeply in debt, which would contribute to a coming revolution. The war also impoverished Britain's treasury, which would impact the British government's policy toward the king's American colonies.
